- Affective Forecasting: the Effects of Immune Neglect and Surrogation
- Studies of affective forecasting examine people’s ability to predict (forecast) their emotional (affective) responses to future events. Affective forecasts underlie nearly all decisions people make and the actions they take. However, people engage in systematic cognitive errors when making affective forecasts and most often overestimate the intensity and duration of their emotional responses. Understanding the mechanisms that lead to affective forecasting errors (e.g., immune neglect) and examining the utility of methods for improving affective forecasting errors (e.g., surrogation) can provide highly valuable information for clinicians as they assist clients in determining their goals both for therapy and for life. The first purpose of the current study was to determine if affective forecasting errors due to immune neglect lead to misjudgments about the relative emotional impact of minor versus moderate negative experiences (i.e., trauma severity). The second purpose was to examine the utility of surrogation for improving affective forecasts. Potential interaction effects between these two variables were also examined. The current study utilized a 2 (Trauma Severity: minor, moderate) X 3 (Prediction Information: surrogation information only, simulation information only, both types of information) experimental design. Undergraduates were recruited via the SONA system and randomly assigned to one of the six experimental conditions. A preliminary study was conducted to obtain surrogation information for use in the main study. All participants in the main study predicted how they would feel 10 minutes after receiving negative personality feedback, using a 10-point scale ranging from (1) very unhappy to (10) very happy. These predictions constitute their affective forecasts. All participants then actually received the negative personality feedback (ostensibly from another participant, a peer, in a nearby room) and reported their actual affective states ten minutes later, using the same scale. These ratings constitute their affective reports. Affective forecasting error was calculated as the difference between affective forecasts and affective reports. Results showed the affective forecasts of participants in the moderate trauma severity condition were significantly less accurate than those of participants in the minor trauma severity condition, providing evidence of immune neglect. Surrogation information significantly improved the accuracy of affective forecasts when participants were deprived of simulation information. Limitations of the current study and implications of the findings are discussed. digital.library.unt.edu/ark:/67531/metadc149566/
- Assessment of Feigning with the Trauma Symptom Inventory: Development and Validation of new Validity Scales with Severely Traumatized Patients
- Currently, only the TSI assesses complex traumatic reactions and patient response styles. However, its feigning scale, ATR, uses a flawed detection strategy and is potentially confounded by experiences of complex PTSD. As a consequence, clinicians using the TSI to evaluate severely traumatized patients have no useful method for discriminating genuine and feigned responding. Several detection strategies have demonstrated utility within evaluations of feigned trauma including the assessment of rare symptoms, symptom combinations, symptom selectivity, and symptom severity. The current study created scales on the TSI according to these strategies using a development sample of 107 severely traumatized patients. Validation of all TSI feigning scales was then performed with a second independent sample of 71 severely traumatized patients using a mixed simulation design. Results found support for each scale's convergent validity with SIRS primary scales (M rs = .52) and discriminant validity with measures of defensiveness on the SIRS (M rs = -.07) and TSI (M rs = -.19). Each scale also produced expectedly mild to moderate relationships with SADS-C clinical scales (M rs = .32) and the SCID-IV PTSD module (M rs = -.02). Support for their criterion validity was only moderate (M ds = .69) when comparing the scores of genuine patients to those simulating disability. Potential explanations for this trend were reviewed, including (a) the impact of comorbidity, (b) the restrictions associated with creating embedded feigning scales, and (c) the influence of simulator knowledge in analogue designs. Limitations of the study and future avenues of research were discussed. digital.library.unt.edu/ark:/67531/metadc68030/
- Decentering and the Theory of Social Development
- The concept of decentering originated with Piaget, who defined decentering as a feature of operational thought, the ability to conceptualize multiple perspectives simultaneously. Feffer applied Piaget’s concept of decentering to the cognitive maturity of social content. This study used Feffer’s Interpersonal Decentering scoring system for stories told about TAT pictures to investigate the developmental hierarchy of decentering for children and adolescents. The participants originated from the Berkeley Guidance Study, a longitudinal sample of more than 200 individuals followed for more than 60 years by the Institute of Human Development at the University of California, Berkeley. The hypotheses tested were: (1) chronological age will be positively related to Decentering as reflected in Feffer’s Interpersonal Decentering scores obtained annually between ages 10 and 13 and at 18; (2) children born into higher class homes would have higher Age 12 Decentering scores; (3) children born later in birth order will have higher Age 12 Decentering scores; (4) children whose parents were observed to have closer bonds with their children at age 21 months will have higher Age 12 Decentering scores; (5) adolescents with higher scores from the Decentering Q-sort Scale (derived from adolescent Q-sorts) will have higher Age 12 Decentering scores; and (6) participants who have higher Age 12 Decentering scores will self-report higher CPI Empathy scale scores at Age 30. A repeated measures ANOVA tested Hypothesis 1. Pearson product-moment correlation coefficients tested Hypotheses 2-6. Age and Decentering scores were unrelated, as was birth order; social class findings were mixed. Parents’ bonds with child and Age 12 Decentering were negatively correlated (closer bonds predicted higher Decentering), as were Age 12 Decentering and Age 30 Empathy (higher early Decentering predicted lower adulthood Empathy). Girls (age 12) tended to decenter more consistently and had higher Decentering scores than boys. digital.library.unt.edu/ark:/67531/metadc149590/
- Evaluating Process Variables in Acceptance and Commitment Therapy
- Acceptance and commitment therapy (ACT) was developed to specifically target experiential avoidance (EA) rather than any specific diagnostic category. A functional ACT manual was presented and used to treat diagnostically diverse clients in a large sliding fee-for-service training clinic. A multiple baseline across participants and behaviors research design was used to evaluate session-by-session changes in EA, values identification, valued action, and clinical distress. The Acceptance and Action Questionnaire-2 (AAQ2), Valued Living Questionnaire (VLQ), and Outcome Questionnaire (OQ-45) were given to measure processes and outcomes given the functional ACT model presented in the introduction to the paper. Baseline included the Structured Clinical Interview for DSM-IV Axis I and II Disorders given across 2-5 50- minute sessions. The treatment phase consisted of 7-10 50-minute sessions. Participants were 10 clients. Four participants completed sufficient treatment sessions (4-9) to test the study hypotheses. Participants generally improved across time, but most improvements could not be attributed to the functional application of ACT due to changes during baseline for AAQ, VLQ-Consistency, and OQ-45. VLQ-Importance significantly improved for all participants given ACT. digital.library.unt.edu/ark:/67531/metadc84296/
- Evaluating the Effectiveness of a Parent training Protocol Based on an Acceptance and Commitment Therapy Philosophy of Parenting
- Thirty-four parents were referred by their CPS caseworkers to participate in one of two ACT for Parenting workshops. These workshops followed a 12 hour treatment protocol based on an acceptance and commitment therapy philosophy of parenting. Briefly, an ACT philosophy of parenting maintains that effective parenting requires awareness and acceptance of thoughts and feelings as they occur in the context of the parent-child relationship. An ACT philosophy of parenting also relies heavily on the identification and commitment to parenting values. Participants were asked to track acceptance and valuing behavior on a daily basis for 25 days prior to the intervention and 25 days post-intervention, as well as to complete a package of self-report instruments designed to measure both ACT specific and general psychological processes, at three different points (pre-, post- and follow-up). Nineteen parents received the treatment, and of those, seventeen provided follow-up data 3-4 months post-intervention. Results indicate statistically significant changes in the expected directions for scores on the BASC-2 Externalizing Composite as well as on the Meta-Valuing Measure. A total of 10 parents also evidenced clinically significant change in the expected directions on a variety of outcome measures. digital.library.unt.edu/ark:/67531/metadc84261/
- Executive Control of Craving: An Examination of College Students
- Previous research has shown that alcohol abuse may cause a deficit in frontal lobe functioning, specifically, areas of the frontal lobe that are related to executive function. Additionally, problems with executive function have been related to increased difficulty in managing cravings to addictive substances. The current study explored the relationship between alcohol use and performance on measures of executive functioning in a sample of 121 traditional college students. Students were given 5 measures of executive function designed to explore mental set shifting, updating, inhibition, sustained attention, and planning. These measures were used to examine the relationship between executive function and craving as measured by the Obsessive Compulsive Drinking Scale. Levels of alcohol use were also examined using the Alcohol Use Disorders Identification Test in relation to executive function performance and family history of alcohol abuse. digital.library.unt.edu/ark:/67531/metadc68067/
- Factors Affecting Revictimization in Survivors of Childhood Sexual Abuse
- Structural equation modeling was used to examine how childhood sexual abuse (and other associated variables, such as family functioning and experiencing multiple forms of abuse) relates to revictimization and psychological distress. Participants were women who participated in Project HOW: Health Outcomes of Women interviews, a longitudinal study that spanned six waves of interviews. Only women with a history of childhood sexual abuse were included in the present study (n=178). Experiencing nonsexual child maltreatment in addition to childhood sexual abuse appears directly related to adult sexual and physical revictimization and indirectly related to psychological distress. Childhood sexual abuse alone was not predictive of revictimization or psychological abuse. This suggests that other mediating factors may explain the relation between CSA and revictimization found in other research. Clinical implications based on the results of the present study emphasize the importance of identifying children who have experienced multiple forms of abuse as particularly at risk for future victimization. In addition, providing interventions with a focus on education and empowerment might decrease risk for future violence and subsequent emotional maladjustment. Potential future research could examine the treatment outcomes and efficacy of these interventions as well as identify those mediating factors that increase the risk for adult revictimization for those individuals who experience only childhood sexual abuse. digital.library.unt.edu/ark:/67531/metadc30453/
- Implementation of a Therapy Group for Wives of Veterans with Posttraumatic Stress Disorder: Development and Preliminary Outcomes
- The purpose of this study was to develop a manualized therapy group for wives or significant others of veterans with posttraumatic stress disorder and to evaluate its effectiveness in reducing wives' psychological symptoms. A second aim of the study was to determine if women's involvement in the wives group resulted in decreases in their husbands' PTSD symptoms. Women recruited for the study were administered pre-test measures during a screening session. They then participated in a 9-session manualized therapy group designed by the researcher that included psychoeducational, process, and support components. Examples of group topics included psychoeducation regarding PTSD, assertiveness and communication, intimacy, self-care, and stress management. After completing the group sessions, participants were asked to complete post-test measures. Other factors explored in this study included marital satisfaction, perceived social support, general satisfaction with the group, and demographic variables. Results indicated that wives who participated in the group treatment exhibited significant decreases in secondary stress symptoms and increases in marital satisfaction from pre-test to post-test. The majority of participants also reported high levels of satisfaction with the group process. Therefore, it appears that the group protocol presented in this study could be a useful tool in the treatment of wives of veterans with PTSD. The results of this study have potential implications regarding the clinical treatment of families of veterans with PTSD and the development of future programs within the VA system. digital.library.unt.edu/ark:/67531/metadc68036/
- Intimate Partner Violence Among Female Undergraduates: The Role of Language in the Development of Posttraumatic Stress
- Research findings across a variety of samples (e.g., clinical, shelter, hospital) estimate that 31% to 84% of women who have experienced intimate partner violence (IPV) exhibit symptoms of posttraumatic stress disorder (PTSD). The current study sought to further investigate the abuse-trauma link by examining the relationship between lifetime trauma exposure, type of abuse (i.e., physical, psychological), and perspective-taking abilities (i.e., here-there, now-then). The role of experiential avoidance in the development of PTSD symptoms was also examined. Results indicated that lifetime trauma exposure (β = .31) and psychological abuse (β = .34) were significant predictors of PTSD symptomatology. Additionally, analyses revealed that experiential avoidance (β = .65) was a significant predictor of PTSD symptoms that partially mediated the relationship between IPV and PTSD symptomatology. Implications of findings are discussed as well as future suggestions for research examining type of IPV and PTSD. digital.library.unt.edu/ark:/67531/metadc84236/
- Is Mattering what Matters: A Validation Study of the Meta-Valuing Measure of Flexible Valuing
- Freely choosing a life direction, or flexible valuing, is a core component of acceptance and commitment therapy (ACT). Initial research suggests that valuing behavior may contribute to psychological well-being, but has been stymied by a lack of an efficient measure. The current study examined the psychometric characteristics of a new measure of flexible valuing, the Meta-Valuing Measure (MVM), in a sample of 532 undergraduates. Exploratory factors analysis revealed 3 orthogonal factors, Valuing (α = .94), Freedom from Values Conflict (α = .92), and Flexibility in Valuing (α = .73). The majority of expected relationships with other constructs were significant including those with measures of values, mindfulness, quality of life, experiential avoidance, and psychological distress. digital.library.unt.edu/ark:/67531/metadc30517/
- Organized Semantic Fluency and Executive Functioning in an Adult Clinical Sample and a Community Sample
- The study investigated an organized semantic fluency task, (the Controlled Animal Fluency Task - CAFT) as a measure of executive functioning (EF) in adults, and the relationship with instrumental activities of daily living (IADL). Participants (N = 266) consisted of a clinical sample (n = 142) utilizing neuropsychological assessment data collected at an outpatient psychological center, and a community sample (n = 124). The clinical sample was a heterogeneous mixed neurological group including a variety of health conditions and comorbid anxiety and depression. The CAFT Animals by Size demonstrated a significant positive correlation with Category Fluency (r = .71, n = 142, p < .001) , Animal Fluency (r = .70, n = 142, p < .001), and with other, established neuropsychological measures. The CAFT Animals by Size condition demonstrated a significant moderate negative correlation with IADL for the sample as a whole (r = -.46, n = 248, p < .001), and for the clinical sample (r = -.38, n = 129, p < .001), but not for the community sample. In a hierarchical regression analysis, CAFT Animal by Size explained additional variance in IADL (ΔR2 = .15). In a hierarchical regression analysis predicting IADL with the control variables entered first, followed by Category Fluency, with CAFT Animal by Size entered last, CAFT Animals by Size did not make a significant additional contribution. A stepwise forward regression indicated Category Fluency, education, and Category Switching are better predictors of IADL than CAFT Animals by Size. Normative data for the CAFT were calculated separately for age groups and education levels. Simple logistic regression indicated CAFT Animal by Size was a significant predictor of clinical or community group membership. A second logistic regression analysis indicated the CAFT Animal by Size condition improved the prediction of membership in the clinical versus the community group, compared to the MMSE alone. Applications of the CAFT are discussed. digital.library.unt.edu/ark:/67531/metadc30445/
- Risk and Resilience Faced by Children of Deployed Service Members
- The purpose of this study was to examine the impact of military deployment on children, and the roles that risk and protective factors and parenting stress play in emotional symptoms and behaviors exhibited by children while their parents are deployed. A sample of 143 parents (recruited from all branches of the military) who remained at home while their spouses were deployed completed online self-report questionnaires measuring demographic and background information, child internalizing and externalizing behavior, parenting stress, child adaptability, valuing behavior, family cohesion/environment, and parenting behaviors. The sample primarily consisted of mothers (n = 141) and Caucasian individuals (n = 126), which may limit the generalizability of the findings. Results of the study suggest risk factors including parenting stress, corporal punishment, length of time a parent is deployed, and type of deployment (combat vs. non-combat) were predictive of poorer child outcomes. Protective factors including values consistent behavior, child adaptability, and family cohesion were predictive of better childhood outcomes. Parenting stress served as a mediating variable between the relationship of total risk and child outcomes, while values consistent behavior served as a mediating variable between the relationship of protective factors experienced by children and child outcomes. Military deployments not only impact the service members, but also their families at home. Further study and identification of risk and protective factors faced by military children and families are imperative. Implications of findings are discussed as well as suggestions for future research concerning deployment and impact on military families (e.g. identification and empirical validation of programs to support military families. digital.library.unt.edu/ark:/67531/metadc84206/
- The Role of Experiential Avoidance in Trauma, Substance Abuse, and Other Experiences
- Experiential avoidance (EA) is a process in which a person attempts to avoid, dismiss, or change experiences such as emotions, behaviors, and thoughts. EA is associated with a number of psychological disorders and is generally harmful to psychological well-being. Various studies have explored the role of EA as a mediator, while others have studied EA as a moderator. The current study aimed to further understand and broaden the knowledge of the role of EA in regard to trauma, substance abuse, aggression, and impulsivity by examining relationships between these variables with EA as a mediator and as a moderator. Experientially avoidant behaviors (i.e., substance abuse, aggression, and impulsivity) were related to higher levels of EA. EA was found to partially mediate the relationship between the number of traumatic experiences and posttraumatic stress disorder (PTSD) symptoms, as well as the relationship between substance abuse and PTSD. EA was also found to moderate the relationship between PTSD symptoms and aggression. Findings from the present study as well as its limitations and future directions for research are discussed. digital.library.unt.edu/ark:/67531/metadc149651/
