Relations among Involuntary Stress Responses, Social Support, and Cortisol Output during Acute Social Stress among Adolescent Girls: This investigation utilized data from a previous laboratory-based study to examine the interactive contributions of trait involuntary stress responses (ISRs, e.g., rumination) and perceived familial social support (SS) on the hypothalamic-pituitary-adrenal axis (HPA; as indexed via salivary cortisol) response to acute stress in a sample of 128 adolescent girls ages 12 to 16. Participants completed a modified Trier Social Stress Test (TSST), and physiologic stress response was indexed via six salivary cortisol samples. Dimensions of ISRs and familial social support were entered into regression models to predict total cortisol circulation defined by area under the curve with respect to ground (AUCG; Pruessner et al., 2003) following the TSST. Neither ISRs or SS were associated with cortisol AUCG, nor was there an interactive effect of SS on relationships between ISRs and AUCG. Implications of present results and methodological recommendations for future investigations are discussed. This may be the first investigation to consider the interactive effects of ISRs and social support on adolescent girls' HPA responses. Greater understanding of these factors in this understudied demographic will improve translational science as well as inform risk assessment and intervention development.
Self-Compassion, Body Satisfaction, and Eating Disorders in Male Collegiate Athletes: A Longitudinal Analysis: Research identifies male athletes as a subpopulation at risk for developing eating disorders and disordered eating (ED/DE). Petrie and Greenleaf's sociocultural model proposes that various correlates contribute to the etiology of ED/DE in athletes. Among the correlates, body satisfaction has been identified as a direct precursor to ED/DE symptomatology in male and female athletes. Recent research has noted self-compassion's utility in alleviating the outcomes of poor body image and ED/DE through several pathways. However, researchers have yet to examine self-compassion in relation to body satisfaction and ED/DE in male athletes or the temporal relationship between these variables. This study longitudinally examined the direct and indirect effects of self-compassion on body satisfaction and ED/DE symptomatology in a mixed-sport sample of 452 male collegiate athletes by testing the cross-lagged, temporal relationships among self-compassion, body satisfaction, and ED/DE symptomatology across a four-month time frame. Time 1 self-compassion was neither directly related to Time 2 body satisfaction (β = 0.02, p = .755), nor indirectly to Time 2 ED/DE (β = -0.002, 95% BCaCI [-0.028, 0.014]) when controlling for Time 1 scores. Recent research supports my finding and suggests that the effects of self-compassion on body satisfaction and ED/DE symptomatology may be dependent on gender. In contrast, Time 2 body satisfaction was directly related to Time 2 ED/DE (β = -0.12, p < 0.05), which adds to a substantial body of research in that body satisfaction is a primary antecedent to ED/DE.
Examining the Links between Narcissism Domains and Self-Concept Clarity, Self-Esteem, Attachment, Emotion Regulation, and Aggression: Narcissism is currently being redefined as a multidimensional construct. While some researchers hold that narcissism remains a unidimensional phenomenon, others have suggested that bi- and tridimensional conceptualizations may better represent the construct as well as align more succinctly with the experiences of individuals with varying levels of narcissistic traits. Also, since the latter conceptualizations offer a broader assessment of narcissistic tendencies, they may provide greater accuracy in identifying differing narcissistic phenotypes (e.g., malignant vs vulnerable). Given the variety in conceptualizations of narcissism, it remains an open area as to how their respective domains are associated with various risk factors and behavioral outcomes, particularly within antagonistic forms of narcissism. This thesis explored the multidimensional approaches to defining narcissism and examined the associations between narcissistic traits and attachment style, self-concept, self-esteem, emotion regulation, and aggression. Also, the current study explored how differences in college degree (business vs. psychology) and gender may influence the expression of narcissism and associations with attachment style. Overall, the study provides results relevant for a tridimensional view of narcissism and adds to the literature on narcissism's link with factors involved in personality pathology, gender, and choice of college degree.
Interplay of Race, Gender, Competition Level, Athletic Identity, and Psychological Distress: The Moderating Roles of Social Support and Self-Compassion: The current study consisted of 4,116 student-athletes (Mage = 19.84; women = 66.9%; White = 78.2%) to achieve two purposes when considering the disrupting effects of the COVID-19 pandemic and the cancellation of collegiate sports. First, I examined the relationship between gender, race/ethnicity, competition level, and athletic identity. Though there were no significant differences across NCAA Divisional levels, I found a significant gender by race interaction with Black male athletes reporting stronger athletic identities compared to White male and female athletes as revealed by post-hoc analyses. Second, I examined the relationship between athletic identity and psychological distress and found that when social support and self-compassion are both low, there is a moderate, positive relationship between athletic identity and psychological distress for the White female athletes. Additionally, there were main effects for self-compassion and social support where higher levels were related to lower psychological distress among the White female athletes and Latino/a athletes. For the Black male athletes, there was a main effect for only self-compassion. There was a significant self-compassion by social support interaction for the Black female athletes and White male athletes, suggesting that when self-compassion is low, or high, there are higher levels of psychological distress experienced when social support is low. Implications of the findings, limitations, and future directions are discussed.
Moderating Variables on the Relationship between Parent-Child Bonds and Mature Decentering: Developmental psychology aims to elucidate how children's early relationships influence their interactions with the world. Piaget's cognitive development theory is often noted when discussing development, and although his cognitive descriptions of decentering (i.e., perspective taking) were compelling, they neglected interpersonal contexts. Accordingly, Feffer conceptualized decentering within a social context. To expand on Feffer's consideration of the social context, the current study explored early parent-child bonds and their impact on child development, specifically interpersonal decentering, in adolescence. In the present secondary analysis of data from the Institute of Human Development longitudinal Guidance Study at the University of California, Berkeley, I hypothesized that, for both boys and girls, conflict with relatives and a parent's nervous instability would moderate the association between early strong parental bonds and more mature decentering at ages 12.5 and 18 years, and that more imaginative play, introspection, and better physical health would moderate the relationship between strong father-son bonds at age 21 months and the son's more mature decentering at age 12.5 and 18 years. The findings revealed that the association between strong father-son bonds at 21 months and the son's more mature decentering at age 12.5 was strongest when the son was less introspective compared to when the son was more introspective. When sons were in better health at ages 5-10 years and 11-17 years, their father-son bonds at age 21 months were more strongly related to more mature decentering at age 18 compared to sons who were in fair to poor health. The current study expands on the impact parental bonds, particularly paternal for sons, have on a child's social cognitive development.
Multicultural Training and Program Climate in Masters Sport Psychology Programs: Little is known about the current state of multicultural training within sport psychology master's programs. The study explored students' perceptions of their multicultural training and program climate. Importantly, differences in perceptions were investigated based on students' demographic factors, given that students with marginalized identities tend to report less favorable perceptions of and experiences in graduate training. Participants (N = 107) consisted of students and recent graduates of master's level sport psychology programs. Participants reported moderate levels of feeling safe, valued, and comfortable within their master's program, low to moderate levels of multicultural training integration within their curriculum and supervision, and low to moderate satisfaction with their multicultural training. Asian, Asian American, bi/multiracial, Black, African American, Hispanic, and Latino/a/e students, compared to their White peers, reported less satisfaction with their multicultural training, felt less safe, comfortable, and valued within their programs, and perceived less integration of multiculturalism into curriculum and supervision. A multiple regression analysis revealed that, for all students, perceptions of multicultural training integration and reports of feeling safe, comfortable, and valued was significantly related to students' satisfaction with their multicultural training. Discussion focuses on possible explanations for these findings, training implications, and future research directions.
Racial and Ethnic Differences in Trait vs Occasion Unipolar Depression: Unipolar depression is a leading cause of disability and overall burden of disease for millions of individuals across the world. Depressive symptoms (e.g., depressed mood, anhedonia, fatigue, feelings of worthlessness, difficulties concentrating, etc.) can drastically affect an individual's life leading to occupational, social, and personal impairment. Past research shows significant ethnic and racial differences in depression rates and treatment. Moreover, previous literature has also begun to explore the multidimensional nature of depression, investigating its occasion-like (or episodic) and trait-like (or stable) factors. However, prior studies have not explored differences in occasion and trait depression by race or ethnicity, nor have they explored these questions in nurses, a group that faces substantial workplace stressors. To redress these gaps, the current study investigated trait and occasion depression in a large sample of nurses (N = 390) tracked across 12 months and aimed to understand whether trait versus occasion rates of depression differed by racial and ethnic minority status. Findings indicated substantially more trait depression (65.93%) than occasion depression (34.11%) across the year in nurses. However, there were no significant differences based on racial and ethnic minority status. Results highlight the importance of understanding depression as a much more stable aspect of an individual's personality, instead of merely viewing it as a direct response to changes in an individual's external environment. Additionally, findings suggest that focusing on adaptation of more long-term skills to target trait-like depression may be more helpful for nurses experiencing depression.
Survivor vs. Victim: Self-Labeling of Trauma Victims and Its Implicit Impact on Resilience and Recovery: Past research demonstrates that participants who label themselves as ‘victims' experience worse trauma-related outcomes than those who label themselves as ‘survivors.' Self-labeling in trauma research is typically measured using a dichotomous measure where participants choose either victim or survivor, but this construct may be better conceived as more continuous. The current study assessed self-labeling as a possible continuous construct and explored its predictive validity. To capture self-labeling as a continuous construct, we created and utilized a new scale, the Trauma Self-Labeling Measure. Two hundred eleven participants completed a battery of questionnaires to measure self-labeling and four trauma-related outcomes: posttraumatic stress symptoms (PTSS), depression, anxiety, and resilience. When tested on the continuous trauma self-labeling measure, an overwhelming number of participants chose in-between victim and survivor (78.9%) which suggests self-labeling is better assessed using a continuous measure than dichotomous. However, correlation analyses revealed that the continuous self-labeling measure was not significantly correlated to the four trauma-related outcomes, whereas the dichotomous self-labeling, continuous victim, and continuous survivor measures were. When conducting post-hoc analyses, we found an unexpected positive correlation between the continuous victim and survivor self-labeling measures. This unexpected positive correlation suggests that self-labeling is not a singular construct, as previously assumed, but rather is composed of separate victim and survivor constructs. In conclusion, the current study provides the first empirical evidence to support the idea that self-labeling is more continuous than dichotomous and composed of two separate constructs of victim and survivor.
Testing Family Functioning and Psychosis Risk Across Race and Ethnicity: Family functioning has long been a focus of research in psychopathology. Decades of research has shown that family factors are associated with symptom severity, relapse, functional outcomes, and conversion to psychosis among at-risk individuals. Previous studies suggest family functioning varies across cultures, which raises the possibility that associations between family factors and psychopathology may also differ by culture. Furthermore, family functioning assessment generally involves instruments that have not been systematically validated for use with individuals from diverse cultural backgrounds. The current study used data from the Adolescent Brain Cognitive Development study (N = 11,138) to: (1) evaluate three family functioning scales (i.e., Family Environment Scale, Child's Report of Parental Behavior Inventory, Parental Monitoring Survey) and the Prodromal Questionnaire – Brief Child version for measurement invariance across racial/ethnic groups; (2) investigate the relations between family factors and psychosis; and (3) compare relations derived from Step 2 between racial/ethnic groups. Full scalar invariance was tenable for the CRPBI and the PQ-BC, providing statistical support for mean comparisons across groups. The FES and the PMQ lacked scalar invariance, which suggests mean comparisons across groups may not be appropriate. The CRPBI and the PMQ are significantly associated with the PQ-BC, and all three family scales had equivalent relations with the PQ-BC across groups. The current study highlights the importance of evaluating assessment instruments for measurement invariance across racial/ethnic groups. Results also help to connect specific family factors to the etiology of psychotic disorders among US children and adolescents.
Barriers and Facilitators of College Athletes Seeking Mental Health Services: The data surrounding barriers to student-athletes seeking mental health care are limited, but show that stigma is one of the most frequently reported barriers. Further, the effect of sharing demographic identities (i.e., race, gender) between a student-athlete and their mental health treatment provider has not been fully explored. The purpose of this study was to determine the frequency of reported barriers and facilitators to mental health as well as the importance of sport psychologist characteristics as a facilitator of mental health treatment. Participants consisted of student athletes from an NCAA Division I university, representing 11 sports. A series of two-way, repeated measures ANOVA analyses were conducted to determine within-subjects differences in overall reporting of barriers and facilitators, as well as between groups differences in race and gender. Significant differences were found in the rating of barriers and facilitators. Female student-athletes rated sharing a gender identity with their mental health treatment provider as more important than did male student-athletes. The findings of the study may aid athletic departments in developing targeted interventions to lower barriers and increase use of mental health resources to promote psychological well-being among student-athletes.
Elucidating the Effects of Pre-Treatment Expectation Measures on Therapeutic Outcomes: A Meta-Analysis: Client pre-treatment expectations have a significant impact on psychotherapy outcome, therapeutic alliance, and attendance. Client expectations are thought to account for approximately 11-14% of variance in premature termination from psychotherapy. However, measures that conflate treatment beliefs and distinct measurement techniques for the same outcome construct obscure the relationship between expectations and psychotherapy outcomes. Clarifying these associations is necessary to support development of useful methods and processes that support client retention in evidence-based treatments. With drop-out rates of approximately 20% across treatment settings, and as high as 69.4% in psychology training clinics, risk of attrition is a significant liability to effective treatment. The meta-analytic findings presented herein clarify the association of pre-treatment expectations with psychotherapy outcome, considering competing definitions for client expectations and discrepant psychotherapy outcome measurement. Implications for attrition, treatment outcomes, and therapeutic alliance are discussed.
Emotion Regulation in Bipolar Disorder: A Meta-Analytic Review: Bipolar disorder (BD) is a serious mental illness characterized by dramatically differing mood states and marked costs for the individual and society, making it important to find factors associated with the condition. Deficits in emotion regulation have been found across a wide range of mental health disorders and may represent an important risk factor for BD. Literature in this area has large methodological inconsistencies and many conclusions are mixed. Therefore, the current study sought to conduct a meta-analytic review of literature related to emotion regulation in BD. Results suggest that people with BD broadly report more frequent use of maladaptive emotion regulation strategies and less frequent use of adaptive emotion regulation strategies than healthy controls. Of these strategies, the largest effect sizes were found for risk-taking, rumination, impulsivity, catastrophizing, and self-blame. Comparisons to other clinical groups suggest that emotion regulation in BD is largely similar to major depressive disorder and less severely impaired than borderline personality disorder. Moderator analyses of BD samples in different mood states suggest mood state plays a limited role in emotion regulation strategy usage, although some maladaptive strategies may be more common in samples with depressive symptoms. Among emotion regulation strategies, increased positive rumination and suppression may be uniquely characteristic of BD. Findings of this review support the importance of targeting emotion regulation in assessment and treatment of BD. Notably, psychotherapeutic interventions focused on emotion regulation, such as cognitive therapies, may be a key factor in reducing BD risk and episode recurrence.
The Intersection of Miranda and Race/Ethnicity: Effects of Perceptions of Police Officers and Stereotype Threat: The decision of the landmark United States Supreme Court case Miranda v. Arizona (1966) established procedural safeguards to protect custodial suspects' 5th and 6th Amendment rights through requiring provision of what is now known as the Miranda warnings prior to interrogation. Suspects may elect to waive their rights once informed; however, research indicates that many individuals have inadequate knowledge and appreciation of their Miranda rights and consequences of waiving them. Miranda abilities and individual factors are critical factors in determining the validity of Miranda rights waivers. Researchers implicated many factors as influencing waiver decisions (e.g., intellectual ability, psychopathology, age); however, the differential impact of racial/ethnic identity is relatively unexplored. The importance of the investigation of race/ethnicity in Miranda abilities and decisions is underscored by the established differences in perceptions of police officers for racial/ethnic groups. Additionally, scholars have identified a potential presence of stereotype threat contributing to detrimental interrogation decisions. The current study advances previous research through examining the influence of racial/ethnic identity on Miranda abilities and waiver decision. This study also seeks to further the understanding of the effects of perceptions of police officers and presence of stereotype threat through investigate the role of those variables in Miranda abilities and decisions. Using a diverse sample via MTurk, the purpose of the study is to investigate these relevant factors in the intersection of Miranda and race/ethnicity to help inform researchers, forensic practitioners, and policy-makers.
Mending Broken Hearts: Contributions of Attachment Style, Decentering, and Meaning Making for Breakup Adjustment during Emerging Adulthood: Breakups within emerging adulthood (EA) are associated with heightened distress because of individuals' tendency to be preoccupied by and prioritize romantic relationships. Global narrative scoring systems, such as Boals et al.'s meaning making (MM) and Feffer et al.'s interpersonal decentering, can be a useful for analyzing the activated cognitive processing in narratives about stressful events and have been linked to positive adjustment from those events. Attachment may moderate the benefits of processing a breakup. While avoidantly-attached people report lower breakup distress because of their tendency to suppress attachment-related thoughts and emotions, anxiously-attached individuals report prolonged distress due to their tendency to ruminate about the past relationship and to experience continued attachment to their ex-partner. The current study assessed the cross-sectional effects of MM and decentering on depression and breakup non-acceptance, as well as how attachment moderates the relationship between decentering and breakup adjustment. Results found higher MM was associated with higher depression and non-acceptance. More mature decentering was related to lower non-acceptance, but was unrelated to depression. Initial MM efforts may evoke more distress as individuals focus on distressing thoughts or emotions previously avoided. Initial decentering maturity may help with breakup adjustment as one effectively reflects on their own and their ex-partner's thoughts, feelings, and behavior. Attachment style did not moderate the relationship between decentering, depression, and non-acceptance. The present study contributes to the literature on processing relational stressors during EA.
The Role of Affiliative and Aversive Personality Traits in Predicting Social Attitudes: Interpersonally aversive, antagonistic, or "dark" traits have been the focal point of research for decades. In more recent personality research, affiliative, prosocial, or "light" traits have become an area of emerging interest. Examining both domains may allow for a more comprehensive perspective to understanding behaviors and social attitudes involved in human nature related to social dominance and authoritarianism. The purpose of this study was to explore the associations among aversive versus affiliative personality traits with social dominance orientation (SDO) and right-wing authoritarianism (RWA). Both SDO and RWA are robustly tied to prejudice and discrimination, as well as other negative interpersonal characteristics. In this way, the current study will help address if expression of SDO and RWA are primarily linked with presence of a negative (aversive traits) or more so with the absence of a positive (affiliative traits) The current study involved a large general population sample of males who were assessed with Self-Report Psychopathy Scale-Short Form (SRP-SF), subscales from the Short Dark Tetrad (SD4), and the Light Triad Scale (LTS), along with variables tapping the multifaceted domains involved in SDO and RWA. In addition to a series of multiple regression analyses, an exploratory structural equation model (ESEM) was tested to uncover the structure and predictive value of aversive and affiliative traits. The findings of this study may help to further understand individual differences in aversive and affiliative dispositions and their link to critical external correlates.
Suicidality Among Service Members and Veterans: Moral Injury, Attachment, and Social Support: Since 2009, the suicide completion rate for military service members and veterans (SMVs) has exceeded rates in civilian populations, with risk highest among young, male veterans. Suicide risk factors include psychiatric illness, low social support, and repeated or prolonged exposure to traumatic events. Recent research further suggests that the experience of unresolved morally injurious events (MIEs) may create lasting feelings of guilt and shame that contribute to psychiatric illness. Additionally, adult attachment plays an important role in coping responses and relational strategies and may influence the degree to which SMVs experience helplessness and isolation that foster suicidal ideation. Protective factors such as social connectedness are important mitigating factors, substantially reducing the risk of suicidality. In the present sample of 206 combat SMVs, higher suicidal ideation was directly correlated with more MIEs, higher attachment avoidance and anxiety, and lower social support. Although neither social support nor attachment anxiety moderated the link between MIEs and suicidal ideation, a significant interaction between attachment avoidance and MIEs emerged, suggesting that higher attachment avoidance increases the risk for suicidal ideation among SMVs reporting more experiences of moral injury. Additionally, findings suggest that higher levels of social support buffer the detrimental effects of attachment anxiety, but not attachment avoidance, on suicidal ideation.
An Uncivil Student and an Antagonistic Professor Walk into a Classroom: How Instructor Behavior During Class Conflict Impacts Learning: Exceptional classroom management (CM) for face-to-face and online classes is vital to instructor success, and importantly, directly impacts students' ability to learn. Classroom conflict may disrupt an instructor's CM and can occur when a student is uncivil (e.g., sidetracks from lecture) or when an instructor misbehaves (e.g., antagonizes students). A small but meaningful line of work suggests that uncivil students and misbehaving teachers negatively impact the learning environment. However, no work has examined how the interaction between an uncivil student and misbehaving teacher impacts learning. As such, the purpose of the current study is to empirically investigate how teacher responses to student incivility impact cognitive learning in an online learning environment. The project evaluated approximately 252 undergraduate students via an online study. Participants watched a video of an online class in which the professor responds to an uncivil student in one of three different ways: antagonistically, positively, or neutrally. Participants then took a cognitive learning quiz based on the lecture and answered questions about their perception of the instructor, uncivil student, and the learning environment. Results of the one-way ANOVA suggest that how an instructor responded to student incivility did not significantly impact cognitive learning. Secondary analyses also indicated that participant perceptions of the instructor, uncivil student, and learning environment did not significantly relate to cognitive learning. Results of the current study evidence both convergence and divergence with prior work, highlighting the importance of continued experimental investigation of the impact instructor reactions to student incivilities has on learning.
Bicultural Identity Integration and Psychological Wellness among Adult Children of Immigrants: Role of Cognitive Flexibility, Affect Regulation, and Adaptive Coping: Guided by the framework of bicultural identity integration (BII), a conceptual model depicting the direct and indirect effects of BII, cognitive flexibility, affect regulation, and coping on psychological wellbeing indicators (i.e., life satisfaction, depression) of adult children of immigrants (ACI) in the U.S. was developed. It was hypothesized that greater BII would contribute to greater cognitive flexibility and affect regulation, which would be associated with more utilization of adaptive coping strategies and greater psychological wellbeing. A total of 240 young ACI from across the U.S. completed the online research questionnaire that measured all variables of interest. Results from structural equation modeling analyses showed adequate model fit with the data. Findings provided support to the indirect effects of BII factors on wellbeing through affect regulation, however, the indirect effect paths are more complicated than what were hypothesized originally. Specifically, higher levels of identity harmony and identity blendedness contributed to more difficulties in emotion regulation, and subsequently, poorer wellbeing. Additionally, both cultural identity harmony and identity blendedness contributed to greater levels of cultural and relational maintenance strategies (i.e., avoidance, forbearance) in the context of intergenerational conflict through affect regulation, but not through cognitive flexibility. Notably, the latent variable of cultural coping strategies retained in the final model was not correlated with wellbeing. Findings are discussed from the BII framework and the sociological context of ACI in the U.S. Limitations, future directions, and implications for counseling, diversity, and advocacy issues are outlined.
Black Male Collegiate Football Players' Experiences of Racial Mistreatment and Its Effects: A Qualitative Analysis: Research examining how these athletes, specifically football players, are racially mistreated in revenue sports in Power Five conferences, as well as the effect of this mistreatment on their health and well-being, has been sparse. Thus, the purpose of my study was to examine current Black male college football players' experiences of racial mistreatment within their lives in general, and their collegiate sport experiences in particular, and to learn how these experiences have affected their health and well-being across their academic, athletic, and social spheres of functioning. Through reflexive thematic analysis, I gathered that (a) the athletes believed that football defines and limits them, (b) they felt misunderstood and isolated on campus, (b) they were dehumanized and criminalized, and (d) they were physically and psychologically exhausted from chronic racial mistreatment. Despite the NCAA making positive strides toward addressing mental health concerns within collegiate athletics, there remains a clear need for more support and nourishment regarding the mental health of Black male college athletes, particularly football players. Further results and implications are discussed.
Cognitive States while Mind Wandering and Associated Alterations in Time Perception: Time perception is a fundamental aspect of consciousness related to mental health. One cognitive state related to time perception is mind wandering (MW), defined as having thoughts unrelated to the current task. Little research has directly assessed the relationship between these two constructs, despite the overlap in clinical significance and the shared importance of attention for healthy functioning. In the present study, I addressed this by having a sample of 40 adults in the United States complete an online sustained attention to response task remotely while answering thought probes related to thought type and time perception. Multilevel modeling results indicated that cognitive factors were related to the judgements of passage of time (JOPOTs; the feeling that time is passing quickly or slowly) while they had little relation to the estimated duration or the accuracy of those estimations. Specifically, JOPOTs were related to attention to task and emotional valence, and the addition of MW, intentionality, and fixed/dynamic thoughts to the models explained additional variance. Duration estimations and JOPOTs were unrelated to each other, suggesting JOPOTs and duration estimations have different relationships to cognitive factors and should be studied as separate constructs. Additionally, results suggested that the heavy use of dichotomization in the MW literature should be shifted in favor of conceptualizing attention to task as a continuous variable. The difference in effects of MW on estimation durations and JOPOTs specifically is novel finding. This is the first study to evaluate the relationship between MW and both duration estimations and JOPOTs, thus it may advance mechanistic and phenomenological understanding of MW which could in turn inform clinical theories of time perception in disorders including ADHD and depression.
Common Strategies for Regulating Emotions across the Hierarchical Taxonomy of Psychopathology (HiTOP) Model: The hierarchical taxonomy of psychopathology (HiTOP) is a novel classification system that adopts both a dimensional and hierarchical approach to psychopathology to address shortcomings. However, the HiTOP framework is descriptive in nature and requires additional research to consider potential mechanisms for the onset and maintenance of psychopathology, such as cognitive-behavioral emotion regulation strategies. To redress this gap, a sample of 341 adults who endorsed ongoing mental health concerns completed self-report measures of emotion regulation strategies and psychopathology. The data revealed a three-spectra HiTOP model consisting of internalizing, thought disorder, and antagonistic externalizing. Results found that psychopathology was most strongly associated with avoidance, catastrophizing, expressive suppression, and self-blame. In contrast, adaptive strategies were generally unrelated to the HiTOP spectra. This pattern was strongest for internalizing, distress, and detachment. Fewer, yet noteworthy unique relationships between the strategies and specific spectra/subfactors were also found. These findings suggest that psychopathology may be best conceptualized as an overutilization of maladaptive emotion regulation strategies. Furthermore, the results indicate there is added benefit to considering these strategies within a hierarchical approach to psychopathology. These associations alert clinicians to potential treatment targets and contribute to an ongoing literature that seeks to identify underlying mechanisms of the structure of psychopathology.
Cross Validation of the Juror Questionnaire of Values and Viewpoints: Sentencing Decisions and Impression Management in Eligible Capital Jurors: The current dissertation had three primary objectives, categorized into two MTurk studies with capital juror-eligible community members: (a) cross-validate the psychometric properties of the JQVV, (b): explore the role of legal attitudes via the JQVV in mock capital sentencing decisions, and (c): examine the JQVV's ability to detect juror social desirability in capital voir dire. Impressively, Study 1 (N = 552) and Study 2 (N = 313) provided strong and consistent evidence for the JQVV's reliability and construct validity. In the mock juror paradigm, punitive legal attitudes on the JQVV (i.e., Crime-Neg, Convict, and Death-Pos), did not directly affect sentencing decisions, however they indirectly influenced the perception of nearly all other legally relevant variables (e.g., evidence type). For example, participants with more punitive criminal justice attitudes evaluated aggravating evidence more favorably which, in turn, increased death sentence verdicts. Study 1 also underscored the concerningly low levels of comprehension jurors have regarding judicial instructions and other relevant legal knowledge (e.g., the definition of aggravating). In Study 2, the support-life and support-death groups evidenced divergent patterns of social desirability, although support-death participants did not dramatically alter their scores between the genuine and social desirability condition. Additionally, the JQVV Pros-Cyn and Justice-Pos scales were moderately effective at identifying social desirability, marking the first ever questionnaire to examine juror response styles. Implications for research, professional practice in capital jury selection, and legal policy are discussed.
The Development and Validation of a Comprehensive Stereotypicality Measure: Racial stereotypicality refers to the degree to which an individual looks like a "typical" member of their ethnic or racial group by considering multiple phenotypical features such as skin tone and nose width. Prior studies have utilized real and photoshopped images to assess perceptions of individuals high in racial stereotypicality. However, no known studies have allowed participants to engage in the self-assessment of their own facial features outside of skin-tone. In the present study, I develop and investigate the underlying structure of a scale which allows Black individuals to self-assess their perceived degree of racial stereotypicality. I accomplished this by developing items, soliciting expert feedback, conducting cognitive interviews, disseminating the proposed scale, and conducting an exploratory factor analysis (EFA) on a sample of 308 Black adults. EFA results produced a three-factor structure influenced by item wording and reverse coding. Findings also indicated that items which assessed one's overall degree of stereotypicality loaded onto a singular, separate factor as originally theorized. Results suggest that reverse coding, item wording, and response labeling may influence factor structure and negatively impact scale validation procedures. Additionally, items assessing overall stereotypicality may address something distinctly different from other items which assess individual features. Therefore, perceived overall racial stereotypicality should be further tested and considered in future research since it performed fairly during exploratory analysis, aligns with proposed theory, and ultimately homes in on perceptions that may have major implications for understanding how Black phenotypical features impact the lives, outcomes, and experiences of Black individuals.
Effects of Enculturation in Neuropsychological Test Performance on the African Neuropsychological Battery in African Americans and First-Generation Sub-Saharan African Immigrants to the United States: This study used an archival data set of 26 healthy adult immigrants from a sub-Saharan African country to the United States (Mage 39.0, SD = 11.36; Meducation 16.33, SD = 2.88; 40.7% male). Additional archival data was used for 32 healthy African American adults (Mage 34.06, SD = 11.18; Meducation 16.16, SD = 2.49; 53.1% male). A bivariate correlation indicated that acculturation to African culture, as measured by the mBIQ (M 49.29, SD = 8.66), was significantly positively correlated with ethnicity, r = .632, p = .000, ηp2 = 0.399. Two-way ANOVAs revealed that African Americans were able to name more animals than African immigrants (F(1, 54) = 4.82, p = 0.32, ηp2 = 0.82) and exhibited greater organizational skills during a task of cognitive set shifting and problem solving than African immigrants, regardless of level of acculturation (F(1, 54) = 4.47, p =.039, ηp2 = 0.078). In contrast, African immigrants scored higher than African Americans on indigenous fruit (F(1, 54) = 7.60, p =.008, ηp2 = 0.123) and object naming (F(1, 54) = 5.59, p =.022, ηp2 = 0.094). Results of the study concluded that there are small variance effects in language tasks as well as strategy-based approaches to tasks of novel problem solving. Implications of these findings are discussed relative to future research as well as clinical practice in the assessment of culturally dissimilar people across a racially homogenous population by pushing the field forward with diversified approaches to neuropsychological testing.
Examining the Role of Emotion Dysregulation and Rumination in the Relationship between PTSD Symptom Severity and Sleep Disturbances: Emotion dysregulation and rumination are involved in the development, maintenance, and treatment of both posttraumatic stress disorder (PTSD) and sleep disturbances. We examined if and how these factors influenced the nature of the relationship between PTSD symptom severity and subjective sleep disturbances among trauma-exposed individuals. Using data gathered from a community sample of 199 trauma-exposed individuals (Mean age = 35.48; 59.80% female), we examined whether there were stronger significant associations between greater PTSD symptom severity and poorer sleep quality/lower sleep quantity at higher (vs. lower) levels of (1) negative emotion dysregulation and positive emotion dysregulation (both included in the same model) and (2) rumination. Participants recruited via Amazon's Mechanical Turk completed the PTSD Checklist for DSM-5, Brief Version of the Difficulties in Emotion Regulation Scale, Difficulties in Emotion Regulation Scale – Positive, Ruminative Thought Style Questionnaire, and sleep quality/quantity items from the Pittsburgh Sleep Quality Index. Results of simple and additive multiple moderation analyses showed that neither negative/positive emotion dysregulation nor rumination moderated the relationships between PTSD symptom severity and sleep quality/quantity. Exploratory analyses showed that negative emotion dysregulation (when examined independently) moderated the relationship between PTSD symptom severity and sleep quality. There were also significant associations between poorer sleep quality/lower sleep quantity and greater PTSD symptom severity at low to average levels of negative emotion dysregulation coupled with any level of positive emotion dysregulation. Findings inform theoretical perspectives on the PTSD-sleep relationship and clinical applications of targeting emotion dysregulation and rumination in the treatment of PTSD symptoms and sleep disturbances for trauma-exposed individuals.
Executive Functioning Processes in Simple and Complex Theory of Mind Tasks: Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of interactions demonstrated an advantage for individuals without diagnosed or suspected autism diagnosis. This study raises critical concerns regarding measurement method error variance and variability of task demands in explaining cognitive mechanisms relevant to social cognitive processes.
Experiences of Black Student Athletes in the Advent of the COVID-19 Global Pandemic: A Qualitative Study: On January 30, 2020, the World Health Organization (WHO) declared the outbreak of the novel coronavirus (COVID-19) a public health emergency of international concern. In March 2020, the United States government imposed impactful safety and confinement measures issued by the Centers for Disease Control and Prevention (CDC) all over the country to prevent community transmission of COVID-19. Institutions of higher education rapidly transitioned to online learning and eliminated in-person engagements in the spring of 2020 as a result of the COVID-19 outbreak. The National Collegiate Athletic Association (NCAA) followed a similar trajectory by shutting down all athletic activities due to the global pandemic. While college students in general notably experienced increased pandemic related distress and mental health concerns (e.g., depression, anxiety) during the early stages of the global pandemic, the disruption of collegiate sport competitions and seasons uniquely and significantly impacted collegiate student athletes and their overall well-being. In this qualitative study, I sought to document and understand the narrative of Black student athletes' experiences of stress and coping during the first two months of the COVID-19 global pandemic and cancellation of collegiate sports. Through reflexive thematic analysis, I found that psychosocial resources such as avoidance, acceptance, mindful self-compassion, health and wellness, and social support, emerged as important coping skills for the athletes in the present sample. Practical implications for athletes, coaches, support staff, mental health providers, and administrative leaders within college athletics are identified and discussed.
Experiences of Divine Grace in Mainline Protestants: A Consensual Qualitative Approach: The empirical study of grace, a relational virtue nestled within the fields of positive psychology and the psychology of religion and spirituality, has had a relatively slow start. Since research on experiences of grace is in the beginning stages, the purpose of the current study was to provide rich, context-based, qualitative data to describe (a) mainline Protestants' experiences of, and beliefs about, grace (e.g., common grace, justifying/saving grace, sanctifying grace, accepting grace), (b) how mainline Protestant Christians experience the interplay between divine grace and forgiveness (i.e., self-forgiveness, other-forgiveness), and (c) how mainline Protestant Christians experience the interplay between divine grace and humility. Interviews were conducted with 28 community adults who were affiliated with a mainline Protestant church. Results indicated that mainline Protestant Christians have varying beliefs about divine grace and how it is related to both the present moment and the afterlife. Divine grace was often defined as, or associated with, other relational virtues (e.g., forgiveness, love), and participants occasionally defined grace as a gift. Divine grace was further described as being instrumental in mainline Protestant Christians' experiences of (a) self-forgiveness, (b) other-forgiveness, (c) acknowledgement of personal weaknesses and limitations, and (d) connecting with others who are different. I conclude by discussing my findings in light of the present literature on divine grace.
Middle Childhood Behavioral Attachment Dimensions (MCBAD): Development and Validation of an Observational System for Coding Dimensions of Attachment Security in Middle Childhood: Middle childhood is the least understood developmental period in the attachment literature, likely due to active reorganization of the attachment system during this stage. Coinciding with increased cognitive and socioemotional competencies, middle childhood attachment begins to transition from relationship-specific attachment to general attachment representations. While parents continue serving as the primary attachment figure used as a secure base and safe haven, noticeable shifts occur in terms of the need for availability over proximity to attachment figures and the child's involvement in maintaining the attachment relationship. Currently, there is no dominant conceptual or methodological approach for studying attachment in middle childhood. The present study sought to develop and validate an observational coding system examining middle childhood attachment using a dimensional approach. The Middle Childhood Behavioral Attachment Dimensions (MCBAD) system demonstrated mixed reliability and validity compared to other established attachment measures. Compared to traditional categorical attachment measures, this study provides evidence for the utility of an anxiety-avoidance dimensional attachment scale in childhood. Additionally, the MCBAD is the first observational system that examines both nonverbal and verbal attachment behaviors in an unstructured separation-reunion episode, and findings suggest a need for further examination of verbal attachment during this developmental stage.
Moral Injury Development and Repair in Service Members and Veterans: The Roles of Self-Forgiveness, Perceived Social Support, and Causal Attributions: Moral injury (MI) among military personnel is a harmful condition caused by perpetrating, failing to prevent, or witnessing atrocities that violate one's deeply held morals or values. The current study built on the existing literature by exploring predictors of MI, specifically trait self-forgiveness (TSF), state self-forgiveness (SSF), perceived social support (PSS), and causal attributions (CA) following potentially morally injurious experiences (PMIEs) in service members and veterans. Participants were 92 U.S. military service members and veterans. The main findings were that TSF and PSS were both significantly negatively associated with MI in bivariate and multivariate analyses. Further, TSF and PSS were examined as potential moderators of the relationship between PMIEs and MI, but these moderation analyses were not significant. Given that some studies provide evidence for different symptom profiles between categories of PMIEs (i.e., PMIE-Self, PMIE-Other, and PMIE-Betrayal), the relationship between the different categories and TSF were explored. Of the three PMIE types, only PMIE-Betrayal was a significant negative predictor of TSF. Finally, CA was explored as a potential mediator of the relationship between TSF and MI outcomes, but this mediation analysis was not significant. Limitations, directions for future research, and implications for clinical practice are included for discussion.
Personality as a Predictor of Draft Selection and Performance in Professional Baseball Players: Research has demonstrated that personality factors are associated with sport performance as measured by coach ratings and objective performance outcomes, as well as factors/behaviours that are understood to be facilitative for performance, such as problem-focused coping and quality of preparation. Given the potential utility of personality assessment, professional sport organizations have integrated it into their pre-draft procedures. However, it remains unclear whether such data, particularly at the factor level, can add value to draft selection process, over and above that of past performances. The purpose of the present study was to explore if the Big-Five personality traits are related to draft order and predictive of athletes' future performance in professional baseball. Latent profile analysis revealed two distinct personality profiles amongst 2018 and 2019 draft prospects. The results of the covariate analysis were not significant; however, this was likely due to the small n for class 2. Thus, there might in fact still be a meaningful difference between personality profiles by draft order. The results of a series of multiple regression analyses suggested that personality factors and facets were not predictive of performance in the season following the draft, after controlling for performance in the previous season for both hitters and pitchers. Overall, the results suggest that personality assessment likely does not provide much unique and valuable information for draft selection. However, personality assessment might be valuable from a player development and support standpoint.
Prediction is Not Enough: Towards the Development of a Multi-Faceted, Theoretical Model of Aggression and Violence: Violence and aggression continue to be both public health and economic concerns. The field of violence prediction has undergone a series of changes in an attempt to best assess risk including using unstructured clinical judgment, actuarial measures, and structured professional judgment. Although prediction has become more accurate with improved measures, a new generation has recently emerged with an emphasis on understanding violence, as opposed to merely predicting it, to shift the focus towards violence prevention. In addition to the creation of measures, researchers have sought to identify specific risk factors for aggression and violence including static and dynamic risk factors. Despite research demonstrating associations between neuropsychological and social-cognitive factors, violence risk measures continue to omit these variables. The current study developed a multi-faceted, theoretical model of aggression including social-cognitive, neuropsychological, personality, and psychiatric factors. A community, male sample (N = 1,192) collected through Amazon's MTurk responded to a series of self-report measures and neuropsychological tasks. Utilizing structural equation modeling (SEM), I created a model predicting aggression. Several important paths were significant including from entity theory to aggression, mediated by hostile attribution bias, schizotypy to aggression, mediated by both hostile attribution bias and disinhibition, substance use to aggression mediated by disinhibition, and psychopathy to aggression directly. This model provides a framework for future research that focuses on process factors of violence and aggression.
Queer Resilience: A Mixed Methods Examination of LGBTQ+ Positive Identity, Community Connectedness, and Mental Health Outcomes in Sexual Minority Emerging Adults: Despite significant progress in the acceptance and celebration of LGBTQ+ individuals, there is overwhelming evidence that sexual minorities still face disproportionate levels of health inequity compared to their heterosexual peers. Relative to their heterosexual peers, LGBTQ+ emerging adults may encounter unique challenges with discrimination, stigma, and limited social support as they navigate changes in their educational and occupational environments. Additionally, within the broader public health and LGBTQ+ mental health literature, little is known about the mental health service utilization of sexual minority emerging adults. To address these empirical gaps, a sample of 98 LGBTQ+ emerging adults completed self-report measures of heterosexist discrimination experiences, mental health symptoms, LGBTQ+ positive identity, LGBTQ+ community connectedness, and mental health service utilization. The present study found that LGBTQ+ positive identity and LGBTQ+ community connectedness did not attenuate the significant positive relationship between discrimination and negative mental health outcomes. The present study also found that LGBTQ+ positive identity predicted greater likelihood of mental health service utilization, whereas LGBTQ+ community connectedness did not. Finally, exploratory qualitative analyses yielded deeper understanding of relationships between LGBTQ+ positive identity, LGBTQ+ community connectedness, mental health service utilization, and resilience among sexual minority emerging adults. Implications and future directions for empirical research and clinical practice with LGBTQ+ emerging adults are discussed.
Racial Microaggressions, Racial/Ethnic Identity, and Sense of Belonging among Students of Color: Victims of racial discrimination often experience negative consequences that extend into all aspects of well-being (e.g., psychological, subjective, social). Racial microaggressions describe a series of verbal and non-verbal behaviors that cause harm, perpetuate negative stereotypes, and negate the experience of racial/ethnic minorities. Research has found a negative relationship between experiencing racial discrimination and psychological well-being, as well as a potential buffering effect of racial/ethnic identity. However, less information is available about the existence of these relationships with social well-being. The purpose of this dissertation is to fill a gap in the literature in regard to racial microaggressions, racial/ethnic identity, and social well-being in 453 racially diverse undergraduate students. Quantitative results indicated that African Americans reported higher levels of racial microaggressions and racial/ethnic identity than other groups, racial microaggressions were negatively associated with sense of belonging, racial/ethnic identity was positively associated with sense of belonging, and the association between racial microaggressions and sense of belonging was not moderated by racial/ethnic identity. Qualitative analyses using the conventional content analysis revealed two clusters of facilitative behavioral expressions of university/community inclusion: (a) interpersonal expressions of inclusion and (b) systemic expression of inclusion. I conclude by discussing limitations, areas for future research, and implications for counseling.
Some Things Change and the News Stays the Same: Contextual Factors of Mainstream News Viewing and Racial Attitudes: Considerable media research has established that much of mainstream, United States based news is historically rife with content that both implicitly and explicitly reinforces popular cultural norms. Combined with a history full of inequities towards marginalized groups, many of which were based on race, consumption of mainstream news has been linked to increased hostility and more negative attitudes towards non-Whites in the United States. That said, much of this work views news from a monolithic perspective of news programming, irrespective of the differences in political orientation or broadcast integrity. By using quantitative assessments of how various mainstream news programs score on both left/right and fact/opinion-based dichotomies, the purpose of the present study is to address these gaps. As models for how mainstream news consumption is related to existing race-related attitudes, theoretical foundations of cultivation theory (how long viewers watch), the motivation and opportunities model (if viewers are motivated in their viewing) and social ecology theory (who viewers are), were used in relation to these dichotomies. However, overall results suggest that, while time spent with news, race, and gender appear to affect news consumption's relationship with race-related attitudes, preference for left vs. right wing news and fact vs. opinion-based was less relevant, with marginal effect sizes at best. Implications and future directions considering these results are discussed.
Spiritual Fortitude and Mental Health amidst the COVID-19 Pandemic: The COVID-19 pandemic is a global traumatic stressor affecting millions of individuals worldwide. Traumatic events often cause significant resource loss and negatively affect mental health and emotional well-being. In the wake of trauma, many people draw on religious or spiritual faith to cope with adversity and suffering. One construct that has received increased attention within the field of religious/spiritual coping is spiritual fortitude (SF). SF refers to the one's ability to consistently draw on spiritual resources to transcend negative emotions in the face of stressors. In this study, I recruited 255 participants who had lived during the COVID-19 pandemic. Participants completed measures of resource loss, religious/spiritual struggles, SF, religious commitment, depression, anxiety, and post-traumatic stress disorder (PTSD) symptoms. The overall results suggested participants utilized a wide range of coping strategies (e.g., religious/spiritual, social, health practice) during the COVID-19 pandemic. Both resource loss and religious/spiritual struggles were positively associated with mental distress. SF buffered the deleterious relationship between resource loss and mental distress. Specifically, for individuals high in SF, the relationship between resource loss and mental distress was weaker than for individuals low in SF.
Trauma, Posttraumatic Stress Disorder Symptoms, and COVID-19 Impacts among South Asians: South Asians are the third fastest growing racial/ethnic minority group in the United States with distinct cultural characteristics. The coronavirus disease 2019 (COVID-19) pandemic has disproportionately impacted racial and ethnic minorities in the U.S, including South Asians, across several life domains: work, home life/education, social activities, economic, emotional and physical health, infection, quarantine, and positive changes. The COVID-19 pandemic may have critically impacted South Asians with traumatic event experiences and posttraumatic stress disorder (PTSD) symptom severity across several life domains. Limited work suggests high rates of interpersonal traumas and substantial PTSD symptom severity in the South Asian community. Uniquely, the current study examined which life domains impacted by the COVID-19 pandemic associated with a greater count of traumatic event types, interpersonal vs. non-interpersonal traumas, and PTSD symptom severity. Results revealed that negative experiences in social activities, as well as distress in economic, emotional, and physical health domains, were significantly associated with the count of traumatic event types. Negative social activity experiences, and distress in the economic and emotional health domains, were also significantly associated with PTSD symptom severity. Quarantine and physical health domains significantly associated with the count of interpersonal traumas, while COVID-19-related experiences (in social, quarantine, and infection domains) significantly associated with the count of non-interpersonal traumas. Findings inform clinically relevant pandemic research in a vulnerable population and provide trauma and PTSD prevalence estimates in the South Asian community.
Untangling Relational Trauma: A Symptom Network Model of Complex Posttraumatic Stress Disorder within a Relational Framework: The recent inclusion of complex posttraumatic stress disorder (CPTSD) within the International Classification of Diseases, eleventh edition (ICD-11) prompted scholars to re-evaluate treatment guidelines for traumatic disorders. The present study aimed to conceptualize dyadic, community, and systemic connections within the context of ICD-11 traumatic disorders and investigate unique associations between factors capturing relational quality. The current study additionally utilized a novel network modeling approach to explore the CPTSD symptom network structure using a college sample of trauma survivors. Consistent with generations of theory and research, relational quality factors associated with the disturbances in self-organization (DSO) symptom cluster, and anticipated discrimination associated with both relational disturbance and sense of threat. Affect dysregulation, re-experiencing, and relational engagement emerged as most central within the CPTSD symptom network, providing evidence towards the role of affect regulation in relational functioning, while intersectional discrimination associated with both the PTSD and DSO symptom clusters. Findings from the present study provide context to the potential application of a relational and systems focused intervention.
Collegiate Student-Athletes' Psychological Distress and Counseling Use during COVID-19: The onset of COVID-19 and cancellation of collegiate sports may have exacerbated student-athletes' psychological distress. Within a national sample of collegiate student-athletes (N = 5755; 66.7% women; 72.3% White), I determined how gender, race, and sport season related to rates of depression, stress, and counseling use. I used a cross-sectional methodology and collected data in April/May 2020. Overall, 26.5% (n = 1526) and 10.6% (n = 612) of the collegiate student-athletes endorsed clinical and high levels for depression and stress, respectively; 25.1% (n = 1443) and 69.7% (n = 4014) reported subclinical and moderate levels of depression and stress, respectively. Few student-athletes reported counseling use before (17.1%) or after (2.3%) the onset of COVID-19; those who reportedly used services endorsed higher levels of depression and stress than those who did not. Female student-athletes reported higher rates of depression, stress, and counseling use than male student-athletes. There were no race or sport season effects. Student-athletes who competed in spring sports endorsed higher levels of counseling use than student-athletes who participated in a fall season sport. Athletic departments must address their student-athletes' psychological distress by facilitating a higher use of mental health services.
Computational and Statistical Modeling of the Virtual Reality Stroop Task: The purpose of this research was two-fold: (1) further validate the Virtual Reality Stroop Task HMMWV [VRST; Stroop stimuli embedded within a virtual high mobility multipurpose wheeled vehicle] via a comparison of the 3-dimensional VRST factor structure to that of a 2-dimensional computerized version of the Stroop task; and (2) model the performance of machine learning [ML] classifiers and hyper-parameters for an adaptive version of the VRST. Both the 3-D VRST and 2-D computerized Stroop tasks produced two-factor solutions: an accuracy factor and a reaction time factor. The factors had low correlations suggesting participants may be focusing on either responding to stimuli accurately or swiftly. In future studies researchers may want to consider throughput, a measure of correct responses per unit of time. The assessment of naive Bayes (NB), k-nearest neighbors (kNN), and support vector machines (SVM) machine learning classifiers found that SVM classifiers tended to have the highest accuracies and greatest areas under the curve when classifying users as high or low performers. NB also performed well but kNN algorithms did not. As such, SVM and NB may be the best candidates for creation of an adaptive version of the VRST.
Differential Treatment and Outcomes of Racial and Ethnic Minorities in Psychotherapy: Therapeutic alliance has been consistently demonstrated as a robust predictor of treatment outcomes, though the time in psychotherapy at which therapeutic alliance best predicts outcomes is unclear. Unfortunately, evidence suggests that racial and ethnic minority clients typically form weaker therapeutic alliances in treatment. The weaker development in therapeutic alliance among racial and ethnic minority clients may mediate discrepancies in treatment outcomes, including higher dropout rates. The purpose of this study was to explore this possibility by (1) investigating the temporal relationship between therapeutic alliance and treatment outcomes and (2) examining differences in therapeutic alliance ratings and treatment outcome, including unilateral termination, among racial and ethnic minority clients. The findings of this study may be integral to identifying and addressing psychotherapy treatment disparities that are tied to racial or ethnic minority status.
Diverging Perceptions of Emotional Black and White Female Leaders: Stereotypical beliefs about emotion have been shown to influence perceptions of competence. While emotional White women are often presumed to be generally less competent, emotional Black women receive variable competence ratings due to the intersecting stereotypes concerning both their race and gender. However, it is unclear how perceptions of competence fluctuate in response to anger, a stereotypically male emotion, in comparison to sadness, a stereotypically female emotion. The project at hand utilized participants' responses to a scenario of White and Black leaders engaging with subordinates in their workplace expressing either neutral, angry, or sad responses to an interaction. We aimed to identify if a Black woman leader's expression of anger garnered a more favorable response than a White woman leader's expression of anger in addition to whether both leader's expression of sadness would garner similarly low ratings of competence. Results reveal that perceptions of a woman leader's competence can be influenced by race alone with no significant influence from emotional expression. Specifically, a Black woman leader's competence can on average be rated lower than a White woman's competence regardless of emotional expression. This study provides further evidence that group stereotypes manifest differentially based on context.
The Effects of Coach-Created Motivational Climate of Teamwork Behaviors: This study aims to examine how individual athlete perceptions of motivational climate act as an antecedent and influence beliefs about teamwork behaviors. Specifically, how the positive and negative aspects of coach-created motivational climate are associated with: (a) understanding the team's purpose and the ability to plan to achieve the team's mission, (b) implementing designed plans for team success, (c) assessing team performances and environment, (d) creating alterations focused on increasing the probability for team success, and (e) preserving interpersonal relationships by resolving conflicts effectively. Participants consisted of female NCAA Division I collegiate athletes (N = 536; Mage = 20.13 years, SD = 1.36) from colleges/universities located in 22 of the 50 states. Hierarchical cluster analysis revealed three motivational climate clusters; low task/high ego, moderate task/moderate ego, and high task/low ego. The main effect for motivational climate and the overall model of teamwork and the individual component of their behavioral dimensions was significant. The DDA revealed a single significant function for each of the six (i.e., the overall model and individual overarching components of teamwork) MANOVAs conducted, which indicated the composite measures of teamwork behaviors discriminated between the different motivational climate clusters.
Empirical Correlates of the Personality Assessment Inventory (PAI) in an Outpatient Sample: A Replication and Extension: The Personality Assessment Inventory (PAI) has gained widespread favor since its publication. However, validation studies of its interpretive descriptors remained limited to date. As such, the primary goal of the current study aimed at validating the interpretive descriptors through the lens of empirical correlates using the PDSQ as the external criterion. It also served as a replication and extension to the 2018 study conducted by Rogers and colleagues. The final archival sample included 204 clients from the UNT Psychology Clinic who were administered PAI between May 2016 and December 2020. Overall, reliability and construct validity were strongly supported for PAI clinical scales. Further, the current study replicated large majority of the correlates identified by Rogers and colleagues, which boosted the confidence in reproducible interpretations based on empirical correlates. Importantly, investigation of item-level and gendered correlates provided crucial interpretive implications that were otherwise obscured. For example, item-level correlates refined interpretation by clarifying the nature of scale-level correlates, particularly those of moderate strength. On the other hand, notable gender differences were identified for certain scales, which led to drastic differences in patterns of gendered vs. non-gendered correlates. Finally, several important methodological considerations are proposed in hope to facilitate the empirical research concerning measurement validity, as well as combat the current replication crisis. The need to adopt more stringent standards for effect size, as well as the instability of correlates of moderate strength were discussed. Implications of clinical practice and future directions for research are also discussed.
Gender Role Conflict and Religion/Spirituality: Relatively few studies have explored the relationship between gender role conflict (GRC) and an individual's religious/spiritual identities. This study sought to add to the research on GRC by exploring the experiences of female and male GRC, and expand the understanding of the influence of religion/spirituality (R/S) variables on GRC. Participants (N = 359) were recruited from social media and undergraduate courses and completed an online survey that assessed GRC, a variety of R/S variables, and life satisfaction. Overall, there were some significant differences found between male and female experiences of GRC. In general, the R/S variables did not have a large impact on GRC. However, religious fundamentalism and extrinsic and quest religious orientations were related to specific subscales of GRC. Maintaining congruency between one's personal values and one's religious institution was related to lower levels of specific subscales of GRC. Additionally, GRC was related to lower levels of life satisfaction. Regarding the subscales of GRC, restrictive emotionality was the strongest predictor of lower life satisfaction. By furthering research on the interplay between GRC and R/S, clinicians will be more equipped to handle the repercussions of stereotypical roles within gender and religion, address negative attitudes and behaviors, and lead discussions about finding congruency between one's gender and R/S identities.
How Much Does Sleep Vary from Night to Night? A Quantitative Summary of Intraindividual Variability in Sleep by Age, Gender, and Racial/Ethnic Identity: Habitual (i.e., average or typical) sleep duration and sleep efficiency vary widely by demographic characteristics, including age, gender, and racial/ethnic identity. Despite a wealth of studies on demographic patterns in habitual sleep, these results are often based on cross-sectional surveys, which ask participants to retrospectively recall their "typical" or "recent" sleep. Yet, sleep is a highly dynamic behavior and may fluctuate substantially from night-to-night. This intraindividual variability (IIV) in sleep/wake patterns can be captured a multitude of ways, most commonly by using formula-based calculations. Although there is growing attention on the importance of IIV in sleep, findings on demographic differences are still inconclusive, and there are no guidelines for typical values of IIV in sleep. The present study quantitatively synthesized 8 international data sets (N = 2847 participants, 29,832 total days of sleep data), focusing on examining age, gender, and racial/ethnic identity differences in IIV in sleep measured via sleep diaries, actigraphy, and electroencephalography. Sleep duration and sleep efficiency varied widely from night-to-night within people (duration: 64-119 minutes; efficiency: 5-8%). Different metrics of IIV were strongly correlated within and across sleep measurement types. Younger adults had more IIV in diary and actigraphy sleep duration. Gender differences in IIV in sleep were inconsistent, and non-Hispanic/Latinx and White adults had less IIV in sleep compared to other racial/ethnic minority groups. Results emphasize the importance of assessing IIV in sleep, and show that even among healthy sleepers, sleep varies from night-to-night. Like mean sleep, there may also be disparities in IIV in sleep by demographic characteristics, highlighting a need for targeted interventions to stabilize sleep and improve health.
Inflammatory Biomarker Levels and Vaccine Response: This study was conducted as part of a parent grantwhich examined the relationship between components of sleep and antibody responses to the flu vaccine in a population of 392 nurses working at two large hospitals. During/after sleep data was collected, nurses had blood drawn at four time points: immediately pre-vaccination, 1-, 6-, and 11-months post vaccine to obtain serum for detection of anti-influenza antibodies measured with an HI (hemagglutination inhibition) assay. Additionally, the inflammatory biomarkers IL6, IL1-β, TNF-α and CRP were measured at the pre-vaccine time point only to determine any correlation between the markers and antibody response. Data was analyzed using a hierarchical regression. In the first step, analyses assessed whether each change/average in cytokines over the one-month period had an impact on vaccine response for each of the four viral strains in the flu vaccine. In a second step, analyses assessed whether variables such as insomnia, stress, age, smoking, BMI, and race had any impact on vaccine response beyond the effects exerted through inflammation. The change in association (β) between the primary independent variable and primary dependent variable were examined in order to determine whether there are any suppression effects caused by baseline covariates on the relationship between inflammation changes or averages and antibody response. No relationship was discovered between circulating inflammatory changes or circulating inflammatory averages and antibody response. There was a weak correlation between CRP at Timepoint A and CRP at Timepoint B. No relationship was observed between age and circulating inflammation. The lack of relationship was likely due to the use of circulating inflammatory biomarkers; this may be an insufficient approach to determine chronic inflammatory status.
Investigating the Motivation-Cognition Interface: The Influence of Motivation on the Recognition Old/New Effect and Metamemory: The purpose of this study was to thoroughly review previous work and to create a new experimental paradigm combining recognition memory with value-based incentives and metacognitive confidence judgments, which may provide convergent evidence for the motivation-cognition interface. This paradigm involves a game-like task administering global and local motivational incentives. Furthermore, trial-level metacognitive confidence ratings were gathered to understand the relationship of metacognitive accuracy and value as a function of strategic control of attention and memory and incentive-based motivation. Paired samples t-tests and a repeated measures ANOVA were used to identify differences in recognition performance based on reward incentive, and Goodman-Kruskall gamma correlations between performance confidence estimates were used to measure metacognitive accuracy. The results showed the mean number of recognition hits (correctly remembering previously seen items) were indeed greater for high-value items compared to low-value items. I also report an unanticipated effect of block, such that the hit rate increased for low valued items from Block 1 to Block 2. Unfortunately, I did not find meaningful results for the metacognitive judgments. This study lays important groundwork for subsequent research incorporating physiological testing to provide a much-needed link between mind and brain with respect to motivation and cognition. Moreover, this study provides important evidence about limitations within the current design and of remote experimental testing broadly.
Domain Specific Cognitive Effects of Sickle Cell Disease in Children: Multiple contributors to neurocognitive impairment in individuals with sickle cell disease have been identified. Research indicates that a history of cerebrovascular accidents, such as silent infarcts and strokes are associated with greater cognitive decline among children with sickle cell disease. Additionally, disease effects such as hemoglobin and hematocrit levels significantly effect cognitive performance among this population and should be taken into consideration when examining neurocognitive impairment. Further, previous studies show a significant relationship between child behavior problems, family functioning, and cognitive performance in children with sickle cell, marking those as important targets for intervention among this population. While cognitive decline with increased age is not typically examined in healthy child populations, some research indicates the presence of age effects in those with SCD. A majority of the literature addresses cognitive impairment from a broad perspective, while a limited number of studies have begun to address effects among specific cognitive domains. Using archival data from the National Institutes of Health's Cooperative Study of Sickle Cell Disease, results revealed that disease severity was negatively correlated with some aspects of cognitive functioning, including visual-spatial domains. Additionally, some measures of cognitive performance were inversely correlated with age. Consistent with hypothesized outcomes, family functioning was strongly associated with measures of cognitive functioning. Implications are discussed.
Effectiveness of Treatment-as-Usual among Children with Autism Spectrum Disorder (ASD): Autism spectrum disorder (ASD) presents with difficulties in social communication, repetitive and/or restricted behaviors, as well as variable language development. Individuals with suspected ASD ideally participate in assessments which include measures of cognitive abilities, adaptive functioning, language functioning, and ASD specific measures (i.e., ADOS, ADI-R). Diagnosis of ASD can occur confidently at 2 years of age, however, the mean age at diagnosis is 4-5 years old. Delays in diagnosis are accounted for by lacking professionals and centers with the capabilities to assess ASD, as well as long waitlists for assessments. Early identification and intervention have been shown to provide the best improvements in ASD symptomology. The aim of the current study was to conduct a program evaluation of an autism treatment center that was designed to provide high quality evidence-based interventions. The study determined if treatment-as-usual in that center yields the expected gains in adaptive functioning and corresponding decreases in barriers to learning. Results indicated improvement in scores on standardized direct assessment of milestone achievement and barriers to learning, but no significant improvement in adaptive skills via secondary informant questionnaire measures following 6 months of treatment. The overall sample size was small due to COVID-19 complications, lack of institutional procedures, and limited client pool. Further investigation into the treatment practices and reevaluation strategies for individuals with ASD is required.
