Social Anxiety and Non-Medical Prescription Stimulant Use among College Students
Access: Use of this item is restricted to the UNT Community.
Current evidence suggests that non-medical prescription stimulant (NMPS) use is on the rise, particularly among college students. Identifying individuals at risk for regular and problematic use is a critical step towards the development of effective intervention efforts. A growing body of work has noted that individuals with elevated levels of social anxiety (SA) or social anxiety disorder are at an enhanced risk for developing substance use problems, including NMPS use disorder. Despite the relevance of SA and NMPS use among college students, no studies have attempted to examine subclinical SA or the relation between SA and NMPS use among college students specifically. Thus, the present study sought to extend this area by testing the relation of SA symptoms and NMPS use frequency among college students. A large online study of college students was conducted (N=1604) to identify 252 NMPS users (18-25 years; 68.3% female). A hierarchical linear regression was used to test the moderation of positive prescription stimulant expectancies on SA symptoms in predicting past year NMPS use frequency. A subsample of 15 participants was also brought into the lab to assess subjective (State Anxiety) and physiological (salivary cortisol) responding to a social stressor task. Overall, the current study did not provide evidence that SA, via retrospective self-report or real-time responding was related to past year NMPS use frequency. Additional research is needed to resolve the discrepancies between the present findings and prior work. digital.library.unt.edu/ark:/67531/metadc849701/
Predicting Posttraumatic Stress Disorder Symptoms During Adolescence: A Longitudinal Study of The Role of Hypothalamic-Pituitary-Adrenal (HPA) Axis Dysfunction
Access: Use of this item is restricted to the UNT Community.
Posttraumatic stress disorder (PTSD) is a trauma-related disorder that may develop in response to traumatic or stressful events. Dysfunction of the Hypothalamic-Pituitary-Adrenal (HPA) axis has been implicated in the disorder. Studies support such dysfunction as being a consequence of PTSD, rather than a precursor. However, most studies of the HPA are either cross-sectional or have been carried out in adults. The aim of the present study was to identify whether HPA dysregulation interacts with stressful experiences to increase the likelihood of developing PTSD symptoms in a community-recruited sample of healthy adolescent girls. Adolescent girls (N = 550) and one of their parents participated. Adolescents’ clinical symptoms were assessed at baseline and at a nine month follow-up. Saliva samples were collected from all adolescent participants at waking, 30 minutes after waking, and 8 pm on 3 consecutive days. Flattened diurnal slope of cortisol at baseline was associated with increased PTSD symptoms nine months later. Baseline cortisol awakening response (CAR) per se was not prospectively related to developing PTSD symptoms, but its interactions with stressful experience was associated with elevated PTSD symptoms at follow-up. Effects were small and need to be replicated in samples with more severe stressors, as well as more clinical levels of PTSD. Nevertheless, findings suggest that dysregulated basal HPA functioning may be involved in the development of PTSD symptoms. digital.library.unt.edu/ark:/67531/metadc849771/
Role of Combat Exposure and Insomnia in Student Veterans' Adaptation to College
Access: Use of this item is restricted to the UNT Community.
Since 2002, the number of veterans enrolled in universities has nearly doubled, although 30-40% of veterans fail to complete their degree. While research efforts to understand the challenges veterans face transitioning from military life to college has increased in recent years, few studies have looked beyond the effects of post-traumatic stress disorder (PTSD). Insomnia is the most frequently reported symptom of combat veterans and can have serious implications for college students. The purpose of this study was to examine the role of insomnia and student veteran adaptation to college relative to civilian students. College students (N = 588) were administered a Background Information Questionnaire, the Insomnia Severity Index, the Deployment Risk and Resilience Inventory, and the Student Adaptation to College Questionnaire. Results revealed that students with insomnia reported significantly lower adaptation to college than students without insomnia. Student veterans reported better academic and personal-emotional adaptation to college than civilian students, while civilians reported better social adjustment than veterans. Although combat veterans without insomnia scored consistently higher academic adjustment than non-combat veterans and civilian students, when present insomnia seemed to have a greater negative effect on combat veterans’ academic adjustment relative to civilian students. Furthermore, insomnia mediated the relationship between combat exposure and veteran’s personal-emotional adjustment to college. Implications and future directions for research are discussed. digital.library.unt.edu/ark:/67531/metadc849743/
Stress, Spirituality and Self-Esteem: Correlates of Psychological Quality of Life in an LGB Sample
In the current study, we aimed to explore the relationship between perceived stress, spirituality and self-esteem and how they are related to psychological QOL. We found that our overall model accounted for 58% of the total variance in psychological QOL (adj. R2 = .58, F(10, 136) = 21.79, p < .001) with stress (β = -.37, p < .01) and self-esteem (β = .45, p < .01) as the significant predictors. Additionally we found that spiritual beliefs and practices moderate the relationship between stress and QOL (adj. R2= .49, F(11, 135) = 13.88, p < .001). Lastly, we conducted a principle component analysis (PCA) on our three variables of interest and outcome variable to determine whether the proposed structure of our measures holds true for our sample (i.e., LGB populations). digital.library.unt.edu/ark:/67531/metadc849753/
Impact of Grit on Performance After Mastery- or Performance-oriented Feedback
Grit and achievement motivation have been predictors of behavior in academia and military settings (Duckworth, Matthews, Peterson, & Kelly, 2007), but to date, research on their effects on sport performance has been limited. Given grit's predictive role in other performance domains, grit may be influential in athletes' long-term goal attainment, interacting with their achievement motives and leading to better performances. Athletes' trait levels of grit may influence how they understand and respond to messages received within motivational climates from key personnel such as from coaches and teammates. We examined potential moderating effects of grit on the relationship between motivational feedback and high school soccer players (N = 71, Mage = 15.81) performance on a soccer task, their desire to persist in the task, and their choices of task difficulty. We used hierarchical multiple regression to test the main effects of feedback and grit and to determine if grit moderated the effects of feedback on performance. Grit was a significant moderator of the feedback-shooting performance relationship, accounting for 3.9% of variance. Simple slopes analysis revealed a significant effect for low (B = 13.32, SEb = 4.44, p = .004, t = 2.99), but not high, (B = 2.11, SEb = 4.31, p = .63, t = .49), grit on task success. Grit was not a significant moderator of task difficulty selection or task persistence. These results suggest that for those high in grit, feedback about natural ability or hard work is not particularly influential on performance. However, for low grit athletes, type of feedback matters. digital.library.unt.edu/ark:/67531/metadc849625/
Medical Comorbidity in the Course of Bipolar Disorder
Access: Use of this item is restricted to the UNT Community.
Bipolar disorder is a serious illness affecting approximately 2-4% of the population and is one of the world’s leading causes of disability. In individuals with bipolar disorder, medical comorbidity associated with cardiovascular, respiratory and endocrine disorders is related to increased rates of mortality. Recent updates to multi-system inflammatory related conceptualizations of bipolar disorder focus on the unique power that medical illness and biological processes may play as factors associated with course and outcome in bipolar disorder. The current study examined medical comorbidity and its associations with various demographic and psychological variables in individuals with bipolar disorder, schizophrenia, and major depressive disorder with psychotic features followed for 10 years from their first hospital admission. When compared to an age, gender and race-matched control sample from the population, those with bipolar disorder had significantly higher medical comorbidity across a range of medical diagnoses both at 6 months and 10 years after first hospital admission. Ten years following initial hospitalization, individuals in all three diagnostic groups reported increased rates of diabetes (OR: 2.0 – 3.7), stroke (OR: 4.6 – 7.0) and asthma (OR: 1.9 - 3.1), and individuals with bipolar disorder reported increased rates of cancer (OR = 2.1). A number of psychological and demographic symptoms were examined for their ability to predict the development of medical illness across the assessment interval. Overall rates of medical illness were elevated both early in illness course and 10 years after diagnosis, suggesting that broad sequelae of multi-system inflammation are present early and progress over time. digital.library.unt.edu/ark:/67531/metadc849606/
Self-definition and College Adaptation in Students From the Ronald E Mcnair Postbaccalaureate Achievement Program
While a great deal of psychological research is conducted on college students, less has been done on their adaptation to college. These young adults, as they develop ego identity and differentiate themselves from parents and families, must adjust to the social and academic environment of college. Psychosocial adjustment predicts college retention better than academic predictors do. First generation college students face greater than typical challenges adapting to college. The Ronald E. McNair Post-Baccalaureate Achievement Program exists to aid first generation, lower income undergraduate student who wish to pursue a doctoral degree. Self-definition scored from thematic apperceptive technique stories reflects an individual’s relative freedom from social role constraint. This study examined the role of self-definition and familial understanding and acceptance in this population as predictors of successful adaptation to college. While neither was found to be a significant predictor, family understanding and acceptance was found to be a more defining characteristic of this sample than was self-definition. This suggests that when social support is sufficient, individuals do not need to rely on self-definition. digital.library.unt.edu/ark:/67531/metadc822821/
Longitudinal Prevalence of Disordered Eating and Weight Control Behaviors in Female Collegiate Athletes
Female collegiate athletes have been established as a high-risk group for the development of eating disorders due to the high prevalence rates of clinical and subclinical eating disorders, which have ranged from 1.9% to 16.6% and 4.0% to 26.1%, respectively. Collegiate athletes appear to meet criteria for ED-NOS more often than anorexia or bulimia nervosa, and frequently engage in pathogenic weight control behaviors (e.g., dieting, excessive exercise). To date, only a few studies have examined the long-term stability of eating disorders in collegiate female athletes. The current study investigated the prevalence of eating disorders (i.e., eating disordered, symptomatic, and asymptomatic) and pathogenic weight control behaviors (e.g, binging, vomiting, laxative use) in 325 NCAA-DI female collegiate gymnasts and swimmers/divers across two time points – the beginning of their competitive seasons (Time 1) and during the final two weeks of their competitive seasons (Time 2). By Time 2, 90% of the athletes classified as eating disordered at Time 1 (n = 20) maintained clinical or subclinical eating disturbances. Of the 83 athletes originally symptomatic, 37.3% remained so and 10.8% became eating disordered. Significantly more athletes became satisfied with their bodies over the course of the season than became dissatisfied. The athletes reported using exercise and dieting/fasting as the most frequent forms of weight control behaviors, each of which were used less frequently at Time 2 than at Time 1. The results support overall stability of eating disorder behaviors and classification over the course of a competitive season. Limitations and implications are discussed. digital.library.unt.edu/ark:/67531/metadc822790/
Shame Due to Heterosexism, Self-esteem and Perceived Stress: Correlates of Psychological Quality of Life in a Lesbian, Gay and Bisexual Sample
Sexual minorities experience higher levels of stress than heterosexuals, which in turn affects coping and psychological quality of life (PQOL). Although many sexual minorities remain mentally healthy, a higher prevalence of mental disorders among members of the lesbian, gay and bisexual (LGB) communities exists; thus, LGB PQOL becomes an important area to examine. Several key factors are related to PQOL: shame due to heterosexism, self-esteem and perceived stress. Using minority stress model, I hypothesized that shame due to heterosexism and perceived stress are negatively correlated with PQOL, while self-esteem is positively correlated with PQOL. I hypothesized that collectively shame due to heterosexism, self-esteem and perceived stress account for a significant proportion of the variance in PQOL, that self-esteem moderates the relationship between perceived stress and PQOL and that age moderates the relationship between shame due to heterosexism and PQOL. I calculated Pearson product-moment correlation coefficient and found shame due to heterosexism was negatively correlated with PQOL (r(146) = -.21, p = .009), perceived stress was negatively correlated with PQOL (r (146) = -.69, p < .001) and self-esteem was positively correlated with PQOL (r(146) = .72, p < .001). I conducted a regression analysis and found our model accounted for 59% of the variance in PQOL (adj. R2 = .59, F(3, 144) = 68.88, p < .001). Self-esteem did moderate the relationship between perceived stress and PQOL (p = .029), but age did not moderate the relationship between shame due to heterosexism and PQOL. Results suggest perceived stress and self-esteem play key roles in sexual minorities’ PQOL. Implications are discussed. digital.library.unt.edu/ark:/67531/metadc822796/
Relationship Centrality and Expressive Writing: Understanding Post-breakup Distress
When a romantic relationship ends in dissolution, the ex-partners may experience distress similar to post-traumatic stress or complex grief (i.e., dysphoric mood, feelings of loss, intrusive memories, negative rumination regarding the relationship, and a loss of self-esteem). Interventions designed to reduce post-breakup distress have historically attempted to foster integration of the breakup into the self-narrative through techniques such as expressive writing. Recent research indicates centrality, or heightened integration of an event or concept into an individual’s identity, predicts heightened levels of distress in the case of negative life events, including romantic relationship dissolution. Given the role romantic relationships themselves play in identity formation, exploration is warranted of the potential distress resulting from over-identification with a romantic relationship itself, or relationship centrality, after a breakup has occurred. Furthermore, if an individual has overly-integrated a relationship into their identity, the effectiveness of interventions focusing on further integration of the breakup is called into question. This study explored the centrality of participants’ previous romantic relationships, the distress resulting from the dissolution of those relationships, and the role of expressive writing as a distress reduction tool when centrality is taken into account. digital.library.unt.edu/ark:/67531/metadc822743/
Assessment of Hot and Cool Executive Functioning Following Trauma Using the Traditional Stroop Task, Emotional Stroop Task, and a Novel Implicit Association Test
Individuals who have experienced a traumatic event and develop Post-Traumatic Stress Disorder (PTSD) frequently show deficits in both primarily “cool” and “hot” cognitive executive functions (e.g., traditional & emotional Stroop tasks, respectively) that can be impacted by high affective salience. Given the dimensional nature of psychopathology, questions remain about individuals within the general population who have experienced trauma but do not meet full criteria for PTSD and yet may manifest problems in these areas, especially areas of hot and cool executive functioning (EF). Thus, the current project was designed to assess hot and cool EF in a relatively large sample of individuals from the general population who have experienced trauma and currently demonstrate sub-clinical levels of post-traumatic symptoms. The Stroop task, Emotional Stroop task, and a novel modified Implicit Association Test were utilized to assess EF across a spectrum of individuals with varying traumatic histories and level of post-traumatic symptoms. Results suggest that a greater frequency of trauma experiences was moderately associated with worse performance on both hot and cool executive functioning measures. Specifically, females within the sample evidenced a close relationship between traumatic experiences, post-trauma symptoms, and executive functioning. Clinical and theoretical implications are discussed. digital.library.unt.edu/ark:/67531/metadc822731/
Determinants of Effort and Associated Cardiovascular Response to a Behavioral Restraint Challenge
This study directly tested implications of motivation intensity theory on effort to restrain against a behavioral urge or impulse (i.e. restraint intensity). Two factors were manipulated—magnitude of an urge and the importance of successfully resisting it—with cardiovascular (CV) responses related to active coping measured. Male and female undergraduate students were presented with a mildly- or strongly evocative film clip with instructions to refrain from showing any facial response. Success was made more or less important through coordinated manipulations of outcome expectancy, ego-involvement, and performance assessment. As expected, systolic blood pressure responses assessed during the performance period were proportional to the evocativeness of the clip when importance was high, but low regardless of evocativeness when importance was low. These findings support a new conceptual analysis concerned with the determinants and CV correlates of restraint intensity. Implications of the study and associations with current self-regulatory literature are discussed. digital.library.unt.edu/ark:/67531/metadc822752/
Anger, Forgiveness and Mindfulness: Correlates of Perceived Stress in an Lgb Sample
A sexual minority is someone who identifies as lesbian, gay or bisexual (LGB). According to the Minority Stress Model (Meyer, 2003), sexual minorities encounter significant levels of stress due to their minority group status, thus they are more likely to experience perceived stress. Our cross-sectional, correlational study aimed to explore the relationships between forgiveness, mindfulness and anger and how they are related to perceived stress in a convenience sample of ethnically diverse LGB adults. We hypothesized that: 1) anger is positively associated with perceived stress; 2) forgiveness is negatively associated with perceived stress; 3) mindfulness is negatively associated with perceived stress; and 4) anger, forgiveness and mindfulness account for a significant proportion of the variance in perceived stress. 5) The relationship between anger and perceived stress is moderated by forgiveness. 6) The relationship between anger and perceived stress is moderated by mindfulness. Among LGB adults, the extant literature does not address these four variables in conjunction and the relationships between anger, forgiveness, mindfulness and stress has yet to be explored. Various statistical analyses were conducted, including a hierarchical linear regression to test our model. We found that our overall model accounted for 36% of the total variance in perceived stress (F(5, 142) = 17.31, p <.01) with anger (β = .31, t = 3.55, p = .001) and forgiveness (β = -.21, t = -2.56, p < .05) as the significant predictors. Contrary to prediction, forgiveness and mindfulness did not moderate the relationship between anger and perceived stress in our LGB sample. Limitations, strengths, future research and implications are discussed. digital.library.unt.edu/ark:/67531/metadc822763/
Weigh-in Environment and Weight Intentionality and Management of Female Collegiate Athletes
Research suggests that female athletes, in particular, experience “sport-environment” pressures such as: weight, performance, and body image demands from their coaches, teammates, and judges. These influences in tandem with society’s portrayal of the thin ideal are thought to considerably increase the risk of developing disordered eating problems in this population. Although numerous studies have been conducted over the past decade on the prevalence of eating disorders and pathogenic weight control behaviors among female athletes, few have examined in detail the weight pressures that exist within the sport environment, such as whether or not (and how often) athletes are weighed by their coaches, and how athletes respond to those pressures in terms of weight management practices. In the proposed study, we will examine the weigh-in environment, weight satisfaction, weight management practices, menstrual health, and reported source of nutritional guidance. The sample includes 414 NCAA Division I female collegiate swimmers/divers and gymnasts drawn from 26 universities across the U.S. Participants anonymously completed a series of questionnaires as part of a larger study on student-athlete health and well-being. This study found that 41% of athletes were weighed, and most often by an athletic trainer in private. Despite most weigh-ins were reportedly conducted in a positive manner, the majority of the athletes who were weighed (75%) reported using at least one strategy to manage their weight prior to weigh-ins (e.g. restrict food, increase exercise). Athletes desire to lose weight, caloric intake, and menstrual cycles were not related to whether athletes were or were not weighed. The majority of athletes received qualified nutritional guidance about how to healthfully manage their weight. Overall, weighing is occurring in a more positive manner than expected; however, athletes are continuing to report using unhealthy weight management strategies at a high rate. It seems important for athletic departments to set policies regarding weighing and to continue to provide support and education to coaching and support staff regarding eating disorder identification, referral, and treatment. digital.library.unt.edu/ark:/67531/metadc822846/
Effects of Immaturity on Juveniles’ Miranda Comprehension and Reasoning
Over the last several decades, researchers have documented how impaired reasoning by adult offenders impeded the intelligent waiver of Miranda rights. Logically, it stands to reason that juveniles – who are developmentally less mature and have less life experience than their adult counterparts – would possess even greater impairment, thereby heightening their risk for invalid Miranda waivers. Juvenile Miranda research supports this notion; with some researchers finding that psychosocial maturity, among other factors, affect a juvenile’s understanding of their rights. Yet, relatively few studies have examined its relation to Miranda reasoning and decision-making. Thus, the current study investigated the specific role of maturity in juveniles’ Miranda comprehension and reasoning. Participants included 236 legally-involved juveniles recruited from either a juvenile detention center or a juvenile justice alternative education program. The effects of psychosocial maturity were examined on a variety of Miranda-related measures and assessed a broad range of Miranda abilities. It was found that, in general, immature juveniles performed more poorly on all Miranda measures as compared to their mature counterparts. However, the impact of maturity varied considerably depending on the ability. Specifically, maturity was most important in the context of Miranda reasoning. As a novel addition to the literature, the current study also investigated the effects of developmental timing on maturity (i.e., immaturity-delayed versus immaturity-expected) on Miranda abilities. digital.library.unt.edu/ark:/67531/metadc804854/
Community Gardening: a Novel Intervention for Bhutanese Refugees Living in the Usa
Since 2008, the United States (USA) has resettled thousands of Bhutanese refugees, providing brief financial support and pathways to citizenship. Despite the efforts of governing bodies and voluntary agencies which facilitate resettlement, many refugees struggle with adapting to the vastly different lifestyle, economy, language and social structures. In particular, effectively addressing psychological needs of this population is a challenge for service providers operating within an expensive health care system based on Western constructs of mental health. In response to this challenge, refugee resettlement agencies throughout the country use community gardens to promote psychological healing, self-sufficiency, community engagement, and a return of human dignity. Though success of these programs is being shared in the media, there has yet to be empirical data examining their impact. The current study tested whether Bhutanese refugee engagement in a community garden impacts symptoms of depression, anxiety, PTSD and somatic complaints. The study also investigated whether community gardening is associated with perceptions of social support and adjustment to life in the United States. Quantitative and qualitative data was collected from 50 adult Bhutanese refugees in Fort Worth, Texas. Gardening was significantly related to increased social support overall, a key factor in overall functionality within communal cultures; and specifically perceived tangible support was increased. A significant effect of gardening was also found for adjustment. Although a significant effect was not found for psychological and somatic symptoms, there is still evidence of effects on somatic complaints. Varying results from quantitative and qualitative data warrant further investigation into the nuanced work of clinical research and advocacy with refugee populations. digital.library.unt.edu/ark:/67531/metadc804885/
Interpersonal Decentering in Relationship Breakups: Social Cognitive Maturity and Distress Recovery in Young Adults
The termination of a romantic relationship, be it by breakup or divorce, is a fairly ubiquitous experience. Most individuals will recover from a traumatic experience of this nature; some however, experience substantial difficulties in recuperating that persist over time. For these individuals, relationship termination can invoke a variety of negative physical and psychological health outcomes. This project examines the role of social cognitive maturity, operationalized as Interpersonal Decentering, in recovery following a relational loss. Participants in this study were assigned to a pre/post control or measurement intensive (four visits) condition over the course of nine weeks. Individuals in the latter condition completed a Stream of Consciousness (SOC) task in which they discussed their breakup experience out loud for four minutes. These narratives were then transcribed and scored using the Interpersonal Decentering manual as adapted for Expressive Writing. Results indicate that – for women only – mature social cognition is inversely related to depressive mood at the initial visit. However, it is not related to initial PSTD symptomatology for men or women, nor does it predict decreases in depression and trauma symptomatology from the initial visit to the nine-week follow-up. Implications, limitations, and future directions for research of this nature are discussed. digital.library.unt.edu/ark:/67531/metadc804932/
The Virtual Classroom As a Tool for the Assessment of Automatic and Controlled Processing in Autism Spectrum Disorders
Assessment of executive functioning in neurodevelopmental disorders (e.g., autism) is a crucial aspect of neuropsychological evaluations. The executive functions are accomplished by the supervisory attentional system (SAS) and include such processes as inhibition, switching, and planning. Autism spectrum disorder (ASD) tends to present similarly to other neurodevelopmental disorders (e.g., ADHD). For example, ASD and ADHD may share similar etiological underpinnings in the frontostriatal system of the frontal lobe. Research on executive functioning in ASD has been mixed, thus the precise nature of executive functioning deficits in ASD remains equivocal. In recent years, simulation technologies have emerged as an avenue to assess neurocognitive functioning in individuals with neurodevelopmental disorders impacting frontostriatal function. Simulation technology enables neuropsychologists to assess neurocognitive functioning within a testing environment that replicates environments in which the subject is likely to be in everyday life, as well as present controlled, real-world distractions, which may be better able to tap “hot” executive functions. A Virtual Classroom Continuous Performance Test (CPT) has been used successfully to assess attention in individuals with neurodevelopmental disorders impacting frontostriatal function. The current study aimed to investigate executive functioning in individuals with high functioning ASD using a new construct driven Stroop assessment embedded into the Virtual Classroom. Group differences were found in the Virtual Classroom with distractions condition, indicating individuals with ASD may be more vulnerable to external interference control than neurotypical individuals. digital.library.unt.edu/ark:/67531/metadc804860/
Marital Status and Racial/ethnic Differences in Health Outcomes
Substantial evidence demonstrates that marriage is associated with better health outcomes and lower mortality risk. Some evidence suggests that there are gender and race/ethnicity differences between the marriage-health benefits association. However, previous studies on marriage and health have mainly focused on non-Hispanic White-Black differences. Limited information is available regarding the roles of Hispanics. The present study examined marital status, gender, and the differences between non-Hispanic Whites, non-Hispanic Blacks, and Hispanics, in health outcomes. A retrospective cohort analysis of 24,119 Hispanic, NH White, and NH Black adults admitted to a large hospital was conducted. A total of 16,661 patients identified as either married or single was included in the final analyses. Consistent with the broader literature, marriage was associated with beneficial hospital utilization outcomes. With respect to differences in these benefits, results suggest that married patients, Hispanic patients, and women, were less likely to experience in-hospital mortality. Similar effects were observed in aggregated length of stay with married Hispanic women hospitalized nearly 2 days less than their single counterparts (6.83 days and 8.66 days, respectively). These findings support existing literature that marriage is associated with health benefits, add to the emerging research of a Hispanic survival advantage, and broaden the understanding of marriage and health in terms of differences by racial/ethnicity. digital.library.unt.edu/ark:/67531/metadc801949/
Prevalence and Predictors of Perinatal Mental Health Outcomes
Prior research has identified risk factors that may contribute to the development of maternal stress reactions following childbirth. Specifically, situational factors (e.g., factors associated with childbirth), individual factors, and personality factors, have been explored in a multitude of prior studies. The current study sought to build upon this literature by examining both risk and resilience in a sample of both mothers and fathers via a prospective longitudinal investigation. Baseline assessment of expectant parents occurred prior to the birth of their child, with additional assessment at approximately 1, 6, and 9 weeks post-childbirth. A total of 50 participants completed all four of these assessments. Results indicated approximately 20% (n = 10) of participants endorsed moderate or greater stress symptoms after birth, while 22% (n = 11) also exhibited symptoms of moderate or greater depressive symptoms. Stress reactions were assessed with the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ); validity analyses indicated the PPQ had significantly stronger correlations with convergent measures than discriminant measures. Additionally, participants were randomized into one of two post-delivery study arms: an expressive writing group or an active control group. Although expressive writing results were inconclusive, there was a general effect of time, which may be reflective of a natural recovery process. Given the prevalence of stress and depressive reactions in this sample, and the population, exploration into feasible and accessible treatment interventions is warranted. While these results also suggest a potential natural recovery for some participants, interventions for support in the short-term timeframe after childbirth may continue to be useful. digital.library.unt.edu/ark:/67531/metadc801915/
Cross-cultural Differences in the Presentation of Depressive Symptoms
Epidemiological studies show that China has a lower prevalence rate of major depression than that of Western countries. The disparity in prevalence is commonly attributed to the tendency of Chinese to somatize depression. Empirical evidence of Chinese somatization has yielded mixed results. The present study thus aimed to 1) examine differences in somatic and psychological symptom reporting between Chinese from Macau and Americans in America and 2) identify cultural and psychological variables that would predict somatization. Independent and interdependent self-construals, sociotropy, and emotional approach coping were hypothesized to predict somatization of depression. Participants included 353 Chinese and 491 American college students who completed self-report measures online. Contrary to prediction, results indicated that Americans endorsed a higher proportion of somatic symptoms than Chinese did. Sociotropy predicted both relative endorsement and severity of somatic symptoms for the American sample, whereas emotional expression coping was related to somatization in the Chinese sample. The findings challenge the common assumption of greater Chinese somatization and highlight the importance of context in understanding the relationships between somatization and cultural and psychological variables. Implications of the present study and future directions are discussed. digital.library.unt.edu/ark:/67531/metadc801937/
Spanish Measurement of Adult Attachment: Reliability and Validity of the Experiences in Close Relationships Scale in a Hispanic American Sample
Measures of adult attachment developed in English have been translated and validated in multiple Spanish-speaking countries, yet to this date no self-report adult attachment instrument has been systematically examined for validation with Latinos/Hispanic Americans. The present study examined psychometric properties of a Spanish version of a widely used adult attachment scale, the Experiences in Close Relationships Scale (ECRS), with a bilingual college student sample. Following the dual-language split half (DLSH) quantitative method of evaluating semantic equivalence, 209 bilingual, Latinos/Hispanic American college students recruited from a large public university completed a DLSH version of the ECRS (half English, half Spanish). Internal consistency reliability and DLSH reliability were within acceptable limits, although significantly smaller than coefficients of the English ECRS completed by a large Caucasian sample (n = 459); 3- to 8-week test-retest reliability was also adequate. Exploratory factor analysis revealed a two-factor solution with 35 items accounting for 40% of the variance, which was similar to the English ECRS. Convergent validity was supported by findings that showed significant associations of attachment dimensions with social self-efficacy, self-esteem, depressive symptoms, and comfort with self-disclosure, but not interpersonal trust. Evidence for discriminant validity was found in that attachment dimensions were not significantly associated with social desirability. Theoretical implications, limitations, and future directions of the study will be discussed based on adult attachment theory and cross-cultural perspectives. digital.library.unt.edu/ark:/67531/metadc801946/
Adult Attachment, Acculturation and Help-seeking of Latino College Students
Based on theoretical reasoning and empirical evidence, the present study examined the unique and shared effects of attachment anxiety, attachment avoidance, and acculturation on attitudes toward seeking professional help among Latino college students. The research participants included 149 bilingual Latino college students from a large, public southwestern university. Results of a multiple regression analysis indicated that attachment avoidance was positively associated with both the recognition of need for psychological help and stigma of seeking professional help. Acculturation to American society was found to be statistically insignificant in predicting help-seeking attitudes in this sample of the population. Findings from exploratory questions suggested that Latino individuals would most likely seek help from parents, close friends, and then professionals. This study suggested that Latino individuals with high attachment avoidance acknowledge the potential benefit of professional help-seeking but distrust the process of approaching others for help. Limitations, implications, and future research directions will be discussed. digital.library.unt.edu/ark:/67531/metadc801882/
Associations Between Physical Fitness and Academic Achievement: A Meditational Analysis
Research has illustrated the interrelatedness of childhood physical fitness and psychological wellbeing, psychological wellbeing and academic achievement, as well as physical fitness and academic achievement. In this study, we proposed that psychological wellbeing (self-esteem and depression) serves as a mediator between physical fitness and academic achievement during adolescence. In a sample of middle school children (N = 1,530), significant correlations were found between all three variables (p.0001). A hierarchical regression analysis was performed to assess the associations between physical fitness, psychological wellbeing, and academic achievement. The regression analysis reported a significant partial mediation effect. The results of this study supported the proposed hypotheses, including a mechanism of psychological wellbeing partially mediating the relationship between physical fitness and academic achievement. The findings of this study support the importance of encouraging activities to promote both physical fitness and psychological wellbeing in schools. digital.library.unt.edu/ark:/67531/metadc799486/
The Relation Between Exposure to Intimate Partner Violence and Dating Violence in a Social Information Processing Model Among Young Adults
Dating violence (DV) among young adults, specifically in college settings, is a serious issue with potential severe repercussions – both physically and psychologically – for victims of DV (DV victimization), and even financially on societal institutions as a whole. Exposure to parental intimate partner violence (IPV) has been associated with DV in young adults. Such violent behaviors appear to be associated with a recurrent pattern of aggressive thought processes, content, and arousing emotions. This study investigated the mediating effects of explicit socio-cognitive processes, through the reformulated social information processing (SIP) model, and implicit cognitive processes for exposure to parental IPV on DV perpetration and victimization, as well as the moderating effects of identification with parental figures and emotional arousal for exposure to parental IPV on predicting DV perpetration and victimization. 85 college students (men n = 23, M age = 22.29) were recruited for the study and results revealed that exposure to father-to-mother IPV predicted DV victimization, and that the interaction between exposure to father-to-mother IPV and identification with maternal figure predicted DV victimization. Conversely, identification with a parental figure negatively predicted DV victimization. The results revealed that SIP processes did not mediate the relationship for exposure to parental IPV on DV perpetration, however, SIP process of aggressive responding was positively associated with exposure to father-to-mother IPV and DV perpetration. Next, interaction of exposure to mother-to-father IPV and positive affective arousal is associated with less severe SIP hostile attributions and less positive evaluations of aggression responses. Finally, implicit cognition did not mediate exposure to parental IPV and DV perpetration. digital.library.unt.edu/ark:/67531/metadc799477/
Sleep Duration, Sleep Insufficiency, and Carotid Intima-Media Thickness
Cardiovascular disease is the leading cause of death in the United States. Chronic short sleep duration is also a significant public health problem and has been linked to several markers and outcomes of cardiovascular disease. To date, inconsistency of assessments of sleep duration and insufficiency, use of covariates, and cardiovascular disease measurement across studies limits strong conclusions about the relationship between sleep duration, sleep insufficiency, and cardiovascular disease. The current study examined the association between sleep duration, sleep insufficiency, and a marker of preclinical coronary heart disease (i.e., carotid intima-media thickness) in a community sample using a cross-sectional design. Some evidence for a relationship between sleep duration and cIMT was found, with longer sleep duration predicting higher cIMT in some segments. Additionally, the interaction between sleep duration and sleep insufficiency was significant. However, neither of these effects were significant after adjusting for age and in some cases race/ethnicity, suggesting demographics may explain this association. Actigraphy and sleep diary duration assessments demonstrated significantly different correlations with cIMT in some segments, suggesting the nature of the assessment method may impact the strength or direction of the relationship between sleep duration and cIMT. Limitations and future directions are discussed. digital.library.unt.edu/ark:/67531/metadc799484/
Racial/Ethnic Differences in Social Support
Despite a substantially greater risk factor profile, Hispanics in the United States (US) consistently demonstrate better health outcomes compared to their non-Hispanic White counterparts, an epidemiologic phenomenon termed the Hispanic Mortality Paradox. Emerging hypotheses suggest cultural values regarding relational interconnectedness and social support may help to explain these surprising health outcomes. The present study sought to inform these hypotheses via two aims: the first was to examine racial/ethnic differences in perceived social support, and the second was to examine the relationship between acculturation and perceived social support among Hispanic college students. Non-Hispanic White, non-Hispanic Black, and Hispanic college students (N = 330) completed an online survey for course credit. Contrary to expectations, no racial/ethnic differences in perceived social support were observed, nor was an association between acculturation and perceived social support evident among the sampled Hispanic students. The limited sample size, homogeneity in social support levels across groups, and the restricted range of age and acculturation may have obscured relationships that may exist outside the college environment. Future work should consider a more heterogeneous sampling strategy to better assess these associations. digital.library.unt.edu/ark:/67531/metadc799548/
To Weigh or Not to Weigh? Relation to Disordered Eating Attitudes and Behaviors Amongst Female Collegiate Athletes
Collegiate and elite female athletes have been identified as a subpopulation at heightened risk for disordered eating and pathogenic weight management practices. It was hypothesized that this increases risk may be related to sport specific pressures (such as team conducted weigh-ins), or the use and frequency of self-weighing. It appears that mandatory, team conducted weigh-ins are not salient to female athletes in regards to experiencing internalization, body image concerns, dietary restraint, negative affect, and bulimic symptomatology. Results, however, indicate that frequency of engagement in self-weighing may be influential in the engagement of disordered eating symptoms. Specifically, athletes who weighed themselves three or more times per week reported significantly more internalization of general societal ideals and athletic body ideals. For body image concerns, athletes who weighed three or more times per week reported being more concerned with their body size/shape than all others. With respect to dietary behaviors, athletes who weighed themselves three or more times per week reported engaging in significantly more caloric restriction than did those who weighed less frequently. For negative affect, the athletes who weighed themselves three or more times per week reported significantly higher levels of both anger and guilt. Finally for bulimic symptomatology, athletes who weighed themselves three or more times a week had significantly higher levels than those who weighed once or twice or not at all. digital.library.unt.edu/ark:/67531/metadc799536/
Psychosocial Mediators of the Fitness-depression Relationship Within Adolescents
Adolescence is a developmental period during which boys and girls are at high risk of developing major or minor depression. Increases in fitness have been associated with lower levels of depressive symptomatology and improvements in psychological well-being, yet the mechanisms that underlie this relationship have not been thoroughly examined. Three such psychosocial variables (i.e. body satisfaction, social physique anxiety, and physical activity self-efficacy) have been identified as possible mechanisms and although they have theoretical support, additional research is needed to demonstrate empirically the potential effects of these variables. Self-report measures were used to assess the psychosocial variables and the Progressive Aerobic Cardiovascular Endurance Run (PACER) in conjunction with age, Body Mass Index [BMI], and sex was used to determine an estimate of aerobic capacity (VO2max). Path analyses were used to test the proposed model using version 6.2 EQS Multivariate Software. Results of study revealed that the boys’ and girls’ depressive scores were determined based on the extent that their fitness levels improved their satisfaction with their bodies and lowered the anxiety they experience in relation to real or imagined judgments of their physique. Although all pathways in the model were significant, with the exception of physical activity self-efficacy to depression, differences emerged between the boys and girls in terms of the strength of some of the relations amongst the variables. Limitations include restricted generalizability, self-report measures, and cross-sectional design. Results have implications for individuals in a context intended to improve physical and psychosocial well-being of adolescents. digital.library.unt.edu/ark:/67531/metadc699904/
The Influence of Perceived Stress on Insulin Resistance in Adults with Type 2 Diabetes
Objective: To identify whether perceived stress is a risk-factor for higher cortisol levels and greater insulin resistance in Type 2 diabetic patients, using data from participants with and without diabetes in the National Survey of Midlife Development in the United States (MIDUS), specifically MIDUS II, Project 4. The following hypotheses were tested: (H1a) greater perceived stress would be associated with higher cortisol for Type 2 diabetic participants, (H1b) the perceived stress/cortisol relationship would be stronger for people with Type 2 diabetes than for those without it, (H2) greater perceived stress would be associated with higher Homeostatic Model Assessment-Insulin Resistance (HOMA-IR, insulin-resistance) for Type 2 diabetic participants, (H3a) subjective well-being would moderate the perceived stress/insulin resistance relationship for Type 2 diabetic participants, and (H3b) depression would moderate the perceived stress/insulin resistance relationship for Type 2 diabetic participants. Method: MIDUS, a longitudinal study of over 7,000 American adults, explores biopsychosocial factors that could contribute to variance in mental/physical health. Only complete data were utilized. Type 2 participants (n=115) consisted of 54 males and 62 females ranging in age from 36 to 81 years. Non-diabetic participants (n=1097) consisted of 470 males and 627 females ranging in age from 34 to 84 years. Results: None of the predicted relationships were statistically significant. Waist to hip ratio was significantly related to insulin resistance (r = .31, p = .001). Conclusions: Future studies should collect information about the type and duration of stressors in addition to perceptions about stress for those with Type 2 diabetes. digital.library.unt.edu/ark:/67531/metadc699935/
Psychopathic Traits and Insecure Attachment Patterns in Community-based Subgroups
There is a growing body of research on psychopathic traits in non-clinical populations. This emerging research has documented the prevalence of psychopathic traits in the general population and demonstrated that psychopathy has a similar latent structure as well as similar correlates (e.g., violent behavior, alcohol abuse, and lower intelligence) to forensic/offender samples. Relatedly, there is strong evidence insecure attachment patterns in adulthood are associated with many personality disorders, including psychopathy, but only a few studies have examined the relationship between attachment and psychopathic traits in non-clinical samples (albeit, convenience samples of college students). Thus, two aims of the current study are to: 1) describe and explore the manifestation and expression of psychopathic traits in a large, community-based sample and 2) examine associations between adult attachment disturbances and psychopathic traits in diverse sociodemographic subgroups. Using a cross-sectional design, results showed mean-level psychopathy factor score differences existed only when considering single sociodemographic factors (e.g., age), not an interaction of those factors. Psychopathy factor profiles were also consistent across groups, with higher levels of lifestyle followed by interpersonal, affective, and antisocial traits reported. Regarding the second aim, findings indicated support for the positive association between disturbed attachment patterns in adult relationships and psychopathic traits, although these associations differed in males and females of different age groups. Finally, there was some support for attachment processes acting as a social development pathway toward psychopathy, as insecure attachments in adulthood partially mediated the relationships between age and interpersonal, affective, and lifestyle traits of psychopathy. digital.library.unt.edu/ark:/67531/metadc699993/
Personality and Mental Health Attitudes Among Us Army Rotc Cadets
With the current military mental health crisis, it is important to understand the role of the leader in military mental health. First, the impact of military leader behaviors on the well-being of military personnel is reviewed. Next, the role of leader attitudes as a precursor to leader behaviors is discussed. The relation of leader behaviors to leader personality using the NEO Five Factor Model (FFM) is reviewed, as well as the relation of prejudicial attitudes to the NEO FFM personality factors. A research project is described that attempted to draw these concepts together, assessing the NEO FFM personality dimensions and mental health attitudes of US Army ROTC cadets, the future leaders of the US Army. No significant relations were observed between NEO FFM personality traits and mental health attitudes, even after controlling for Impression Management. Also, the predicted positive correlation between positive mental health attitudes and Impression Management was not found. These results suggest that more research and more refined measures are needed in the area of leader attitudes toward soldier mental health problems, and how those attitudes might impact the soldiers. digital.library.unt.edu/ark:/67531/metadc700103/
Factors That Influence Athletic Trainers’ Ability to Recognize, Diagnose, and Intervene: Depression in Athletes
Athletic trainers (ATs) are professionals who are most directly responsible for athletes’ health care in a sport environment. ATs work with athletes on prevention, diagnosis, and treatment of athletic injury; it is through these interactions that put ATs in an ideal position to recognize the psychological and emotional distress that athletes may suffer. Consequently, the National Athletic Trainer’s Association (NATA) has called for ATs to be competent in implementing psychosocial strategies and techniques (e.g., goal-setting, imagery, positive self-talk), recognizing basic symptoms of mental disorders, and identifying and referring athletes in need of psychological help. I explored ATs’ ability to recognize, diagnose, and provide a referral for collegiate athletes who were presenting with symptoms of depression across three different scenarios. The study examined factors that may impact ATs’ abilities in these areas, including AT gender, athlete gender, and type of presenting problem (e.g., athletic injury, romantic relationship, or sport performance issue). Overall, female ATs were better at recognizing depressive symptoms than male ATs, though both were equally proficient at diagnosing depression. Regardless of gender of the AT, gender of the athlete, and presenting problem, ATs were most likely to refer the athletes to a counselor/psychologist, and to a lesser extent sport psychology consultant (SPC). ATs viewed referrals to an SPC as most appropriate for presenting problems related to sport (i.e., performance problem or injury). The results highlight a possible bias in referrals to an SPC, in that SPCs may not be considered an appropriate referral source for romantic relationship problems. Implications for ATs and recommendations for future research are discussed. digital.library.unt.edu/ark:/67531/metadc700001/
Effects of Religious Attendance on Suicidal Ideation: Examining Potential Mediators of Social Support, Locus of Control, and Substance Abuse
Religion has a well-documented relationship with mental health benefits and has consistently demonstrated an impact on several specific mental health concerns, including suicide, generally finding various religious facets to be inversely associated with suicidal thoughts and behaviors. More specifically, religion has been found to be associated with suicide in a number of ways, including decreased acceptance of suicide, decreased likelihood of suicidal thoughts, decreased likelihood of suicidal attempts, fewer suicide attempts, lower relative risk of suicide, lower suicide rate, and increased reasons for living. Several studies have proposed potential mediators (e.g., social support, locus of control, and substance abuse) of the relationship between religion and mental health, usually in non-clinical samples. The current study sought to examine the association between religious attendance and suicidal ideation using archival data of a clinical sample collected from the University of North Texas Psychology Clinic. Results from this sample revealed no evidence of mediation, instead suggesting a direct effect of religious attendance on suicidal ideation. Two mediation models demonstrated the effects of external locus of control and social support on suicidal ideation. These models are discussed in terms of their directionality, considering the extant research on these associations. Findings of the current study have implications for welcoming the incorporation of salient religious topics throughout treatment in mental health settings, including discussion of religious attendance among those clients who have identified religion as a personal value. digital.library.unt.edu/ark:/67531/metadc699865/
Discrimination and Perceived Stress in Sexual and Gender Minorities: Self-esteem As a Moderating Factor
Sexual and gender minorities are subjected to discrimination and stigmatization which increase vulnerability to psychological co-morbidities (Mays & Cochran, 2001). The mechanisms through which discrimination contributes to distress in lesbian, gay, bisexual and transgender (lgbt) communities can be partially elucidated through the minority stress model. The minority stress model argues that minorities are subjected to negative societal attitudes and discrimination that results in excessive psychosocial stress related to their minority position, which is distinct from daily stress. Meyer’s minority stress model is supported by social stress theoriesand data linking discrimination to stress in lgb samples. Researchers suggest that self-esteem buffers the negative effects of adverse experiences but tests of the moderating effect of self-esteem on the discrimination-distress relationship in ethnic and gender minorities yielded mixed results. Szymanski found that self-esteem moderates the relationship between discrimination and psychological distress in a male sexual minority sample, but this has never been tested in a gender-balanced sexual minority sample. We hypothesized that higher levels of self-esteem are associated with lower overall perceived stress in lgbt adults, and that self-esteem acts differentially in lgbt populations to moderate perceived discrimination. We found that discrimination, self-esteem and the interaction effect between discrimination and self-esteem accounted for 53 percent of the total variance in perceived stress scores, ∆R2 = .38; adj. R2 = .53, F(12, 133) = 14.47, p < .001.When we tested whether self-esteem moderated the relationship between discrimination and stress, discrimination was positively related to stress, β = .13, t(144) = 2.14, p < .05, and self-esteem was negatively related to stress, β = -.63, t(144) = -10.26, p < .001. The interaction between self-esteem and discrimination positively correlated with stress, β = .14, t(144) = 2.29, p < .05. Our findings suggest that self-esteem may alleviate the impact of discrimination on perceived stress, which has important implications for interventions designed to reduce stress in lgbt communities. digital.library.unt.edu/ark:/67531/metadc699842/
An Exploration of the Criterion and Construct Validity of the Self-compassion Scale
Past research indicates that self-compassion has positive implications for psychological health and functioning. However, as a newly specified construct, the literature regarding self-compassion could benefit from a more thorough validation of the primary scale used in this area of research, the Self-Compassion Scale. In the present study, structural path analysis (using Amos) was used to explore the criterion validity of the SCS with four variables which have been theorized to be relevant to self-compassion (caregiver emotional responsiveness, fear of emotion, internalized spirituality, and achievement goal orientation). Initial hypothesis testing indicated support for the path model, with the exception of achievement goals which were not significantly associated with self-compassion. Trimming these paths in a subsequent analysis improved model fit. Interestingly, further analyses of the model indicated that the pairing of participant and parent gender produced substantial differences in path coefficients. Next, correlational and factor analytic methods were used to test the construct validity of the SCS. Correlational analyses found adequate convergent construct validity but some lack of divergent validity between SCS dimensions and conceptually similar constructs (i.e., fear of emotion, social connectedness and self-criticism). Confirmatory factor analysis indicated that a two-factor model fit the data better than the one-factor model proposed by the author of the SCS. The incremental validity of the two-factor model was supported by incorporating a two-factor SCS in the path analysis. In sum, these findings generally support the criterion validity of the SCS through meaningful associations with theoretically relevant variables but cautions that these associations are strongly influenced by gender. It is also strongly recommended that a two-factor model of the SCS be explored in further research to ascertain its incremental utility for understanding self-compassion’s positive effects on psychological health. digital.library.unt.edu/ark:/67531/metadc699856/
Apology and Forgiveness in Couples
Following a transgression, interpersonal forgiveness is one strategy used to restore harmony between the victim and offender. Research also suggests that forgiveness can promote psychological and physical health. Research has shown that an apology from the offender may facilitate the forgiveness process. The majority of studies suggest that when a victim receives an apology, they experience higher levels of forgiveness toward their offender. The purpose of this thesis was to explore the association between apology and forgiveness in a sample of adults and undergraduate students (N = 803). The results are organized in three sections. First, I found a positive relationship between apology and forgiveness, replicating prior research. Second, I created a new measure of transgression severity, and provided evidence of internal consistency, construct validity, and criterion-related validity for this measure. Third, I tested two variables hypothesized to moderate the association between apology and forgiveness. First, there was some evidence that perceived offender humility moderated the association between simple apology and forgiveness. Offenders who were perceived as being more humble when providing a simple apology were granted more forgiveness than their less humble counterparts. Second, there was some evidence that transgression severity moderated the association between a complete apology and forgiveness, but the effect was in the opposite direction as hypothesized. For individuals who reported a transgression of high severity, there was a stronger association between the completeness of an apology and forgiveness than for individuals who reported a transgression of low severity. I conclude by discussing limitations, areas for future research, and implications for counseling. digital.library.unt.edu/ark:/67531/metadc699962/
Diabetes Status of Mexican Americans: Impact of Country of Birth
In order to better tailor treatment to specific populations, factors which contribute to health disparities among different racial/ethnic groups must be examined. Among Mexican American individuals, the high rate of diabetes represents a significant contributor to overall health. The present study focuses on factors affecting diabetes status among Mexican Americans born in either Mexico or the United States using the 2007 – 2008 NHANES data set. Comparisons were made between diabetes status based on self-report and clinical classification using HbA1c. Results indicated that within the diabetic subsample, Mexican Americans born in Mexico were twice as likely to be incorrectly classified as non-diabetic, when they actually were diabetic, when using a self-report method. In contrast, nativity did not result in differences in diabetes incidence using the HbA1c clinical cut-score diagnostic classification. Age, BMI, gender, nativity, and health insurance coverage were found to have varying relationships to diabetes prevalence and HbA1c levels, but time in the U.S. for Mexico-born individuals was not found to uniquely predict diabetes incidence. Analyses also demonstrated that Mexico-born males, as compared to the other groups, had significantly higher HbA1c levels. Further research is necessary to better understand the relationships among these factors. However, findings do demonstrate a need for more objective disease classification, particularly when examining immigration status and diabetes. Additionally, the complexity of these interactions establishes a need for specific health intervention for foreign-born populations which might be missed by self-report screening asking about presence of disease and exacerbated by an oversimplification of the “healthy immigrant effect”. digital.library.unt.edu/ark:/67531/metadc699863/
Learned Helplessness, Locus of Control, and Academic Achievement
To determine the relationship among learned helplessness, locus of control, and academic achievement, data from 86 sixth graders were gathered and intercorrelated. Contingency of teacher-administered rewards and punishments as perceived by school children, and helpless behavior of students as judged by their teachers were measured. The Children's Nowicki-Strickland Locus of Control Scale was used to measure locus of control orientation. A positive relationship between academic achievement and locus of control was found. The contingency of reward scale was found to be predictive of academic achievement and helpless behavior. Virtually no significant relationships were found between any of the other variables and the contingency of punishment scale. Helpless behavior was found to be predictive of low academic success and an external locus of control. digital.library.unt.edu/ark:/67531/metadc663025/
Chemical Aversion Therapy for Morphine Addiction
These studies led the experimenter to investigate the use of chemical aversion therapy using anectine as the aversive stimulus with a morphine addict. The success of Thomason and Rathod with heroin addicts suggested that their experimental method would be useful as a reference while designing this study. The treatment hypothesis was that the patient's use of intravenous narcotic drugs would be eliminated through the application of chemical aversion therapy. Chemical aversion therapy was operantly defined as the injection intravenously of anectine into the patient concurrent with his self-injection of his narcotic of choice. digital.library.unt.edu/ark:/67531/metadc663274/
Sex Differences in Extreme Response Style
The main objective of this investigation was to study the influence of sex on extreme response style as measured by a semantic differential. The previous studies led to a general hypothesis formulated as follows. Normal males and females differ from each other with regard to their mean extreme response style scores with females having the greater extreme response scores on the semantic differential. digital.library.unt.edu/ark:/67531/metadc663641/
A Comparison of Certain Rorschach Indices Between Smokers and Nonsmokers
The purpose of this study was to compare a group of college smokers with a similar group of college nonsmokers on eleven Rorschach indices. The sources of data were thirty-five smokers and thirty-five nonsmokers enrolled in Introductory English courses at Texas Christian University during the 1971-1972 academic year. digital.library.unt.edu/ark:/67531/metadc663598/
Differential Scores of Feminists and Traditional Women on the Ego Strength (ES) Scale of the Minnesota Multiphasic Personality Inventory (MMPI)
Since women in the Women's Rights Movement (Feminists) tend to be educated, career- or goal-oriented, and typically middle-class it was anticipated that these aspects would be reflected in an elevation on the ego strength (Es) scale of the Minnesota Multiphasic Personality Inventory (MMPI). This anticipated elevation was felt to be functionally related not only to career- or goal-oriented behavior and intelligence, but to active participation on an autonomous basis in the Women's Rights Movement as well. Because of the different activities of various Feminist organization, i.e., women's studies programs, consciousness raising, investigations of inequities to women, confrontations with establishment hierarchies, and participation in career and other self-fulfilling activities, it was hypothesized that women who are active Feminists would score significantly higher on the Es scale than a similar group of active women who are not Feminists. digital.library.unt.edu/ark:/67531/metadc663343/
The Efficacy of Anxiety-Relief Therapy and Systematic Desensitization in the Treatment of Snake-Phobic Behavior

Each subject was also administered the MMPI, using,.Form R. digital.library.unt.edu/ark:/67531/metadc663494/
Relationship of Internal-External Locus of Control and Performance in a Weight-Control Program
This study explores the relationship between internal-external locus of control and some characteristics of overweight subjects in a weight-control program in the summer and fall of 1973. Only white, female, over-weight, and obese subjects were used. From this study, it appears that Rotter's I-E concept applies to weight loss. This one significant finding lends support to research that internals control their impulses better than externals and that internals seem to learn and retain relevant information better than externals. digital.library.unt.edu/ark:/67531/metadc663639/
Teaching Two Simple Non-Verbal Syntaxes To Two Autistic Children
The following study had been developed to demonstrate language behavior in subjects that matched or demonstrated deficient language behavior like Sarah's (Premack, 1971). Two autistic children were selected as subjects. These two subjects demonstrated that children who could not normally fulfill the language behavior requirement of selecting specific words, letters, or colored stones, and arranging them in some good temporal sequence, could in fact be taught to do just that activity. In this manner, language deficient candidates more severely damaged than the subjects used by Premack in his study on language difficulties in persons who were "brain damaged,'" could be taught the parameters of syntax and semantics on a non-vocal level, and thereby fulfill the criterion for language behavior, namely that of arranging specific symbols in good temporal sequence. digital.library.unt.edu/ark:/67531/metadc663791/
The Relationships of Locus of Control and Perceived Contingency of Teacher Rewards and Punishments to Academic Achievement
The purpose of the present investigation was to assess the relationships among the contingency of teachers' reactions as perceived by the pupils, the pupils' academic performance, and internality. One might expect that children who perceive their teacher as contingently rewarding and punishing would achieve higher grades and test scores than those who view their teachers' reactions as unrelated to their behavior. It is believed that children's perceptions of the contingencies of their teacher's responses may be more highly related to achievement behavior than the teacher's actual distribution of rewards and punishments. Perceived contingency of punishments and rewards may be important determiners of achievement. The perception of punishments as noncontingent is likely to be negatively related to achievement; however, the same may not be true of noncontingent reward. Indiscriminate dispersion of rewards could have a motivating effect or, as one might infer from Paris & Cairns (1972), no effect at all. Internality and achievement are expected to be positively related, perhaps more so for boys than for girls, as the trend of previous evidence suggests. Because of conflicting reports, no firm expectation can be formulated with regard to sex differences and the effectiveness of IAR+ versus IAR- scores. digital.library.unt.edu/ark:/67531/metadc663111/
Intellectual Appraisal of Mexican-American Children: English vs. Spanish, Reinforcement vs. Nonreinforcement
The purposes of this study are: (1) to make a contribution to the increasingly urgent evaluation of an appropriate measure of the intellectual potential of South Texas Mexican-American children as studied through the community of Charlotte, Texas; (2) to gain some insight into the intellectual abilities of Mexican-American children of Charlotte, Texas when compared to the national norm; (3) to appraise the effects of bilingualism as it relates to the mental development of first through fourth grade children of Mexican- American parentage, particularly through the WISC from the standpoint of the language in which the test is given; (4) to ascertain the value of tangible (candy) and intangible (praise) reinforcement for each correct response yielded during the testing session. digital.library.unt.edu/ark:/67531/metadc663484/
A Comparison of Responses Between Unwed and Married Pregnant Women on the MMPI
The purpose of this study will be to compare unwed mothers with married pregnant mothers on the Depression, Psychopathic Deviate and Hypomania scales of the Minnesota Multiphasic Personality Inventory. The major hypothesis is that the scores of the unwed mother will reflect more psychopathology which will be taken to indicate that the unwed mother's problems antedate their pregnancy. (The term, "psychopathology," as used herein is defined as any maladaptive behavior which is a result of inadequate personality development.) digital.library.unt.edu/ark:/67531/metadc663392/
