Negative affect and positive symptoms of psychosis.

Negative affect and positive symptoms of psychosis.

Date: December 2009
Creator: Crutchfield, Audra
Description: The current study utilized structural equation modeling (SEM) to examine the factor-to-factor relations and temporal associations between disturbances in negative affect (NA) and positive symptoms of psychosis (PP). Data were drawn from a large, public-domain data set (MacArthur Violence Risk Assessment Study). A dimensional approach was used to conceptualize and identify latent variables of NA (depression, anxiety, and guilt) and PP (hallucinations, delusions, and thought disorder) among individuals with a diagnosis of primary psychotic disorder. Results showed that anxiety, guilt, and depressed mood modeled an NA latent variable, and that hallucinations and unusual thought content modeled a PP latent variable. As predicted, results revealed strong, significant cross-sectional (synchronous) associations between NA and PP at each measured time-frame, suggesting that NA and PP occurred concurrently within the sample. Contrary to predictions, no significant cross-lagged effect between NA and PP was identified (10 weeks and 20 weeks respectively).

Factors of the Geriatric Depression Scale that may Distinguish between Four Cognitive Diagnostic Groups: Normal, Mild Cognitive Impairment, Dementia of the Alzheimer's Type, and Vascular Dementia

Factors of the Geriatric Depression Scale that may Distinguish between Four Cognitive Diagnostic Groups: Normal, Mild Cognitive Impairment, Dementia of the Alzheimer's Type, and Vascular Dementia

Date: December 2009
Creator: Cornett, Patricia F.
Description: The purpose of the current study was to explore the relationship between cognitive status and depression in a sample of geriatric patients. Participants included 282 geriatric patients ranging in age from 65 to 96 years who were classified according to diagnosis as: DAT, VaD, MCI, and Norm. All were referred for neurocognitive testing from the Geriatric Assessment Program (GAP) at the University of North Texas Health Science Center (UNTHSC) in Fort Worth, Texas. This study sought to identify factor structures for two versions of the GDS using a geriatric sample of cognitively impaired and intact patients. It then compared these factors to each other to determine whether the GDS-15 is truly a shorter version of the GDS-30. These were then compared to a previously determined factor structure. This study explored whether the four-factors of the GDS-30 are able to differentiate cognitive diagnostic groups. Further, this study sought to identify whether the severity of cognitive decline impacted GDS factor score for each of the cognitively impaired groups. Results revealed a two-factor model of the GDS - 15 and a four-factor model with the GDS - 30. The GDS-15 factors did not differ from the first two factors of the GDS-30. Comparison ...

Moderators of the sociocultural internalization-body dissatisfaction relationship among female undergraduates.

Moderators of the sociocultural internalization-body dissatisfaction relationship among female undergraduates.

Date: December 2009
Creator: Latimer-Kern, Kelsey M.
Description: The sociocultural model of eating pathology is an empirically-supported model explaining eating disorder etiology. The model poses that body dissatisfaction and subsequent eating pathology stems from the unrealistic standards formulated by Westernized society. Although the model has strong empirical support, variables within the model do not account for 100% of the variance in disordered eating. Thus, the current researcher attempted to explore potential moderating factors in the sociocultural model of eating disorders that may help to explain variance currently unaccounted for. In particular, the researcher focused on the relationship between sociocultural internalization and body dissatisfaction, given that this relationship has not been previously explored within the literature. Based on theoretical support, the researcher chose several potential variables to test, including perfectionism, neuroticism, body surveillance, and shame. Primary analyses tested each variable for moderating effects using hierarchical moderated regression, but no significant findings were shown. Results of post hoc analyses showed all variables had significant mediating effects, with the exception of self-oriented perfectionism. The discussion section addresses consistency with previous research, limitations of the present study, treatment implications and guidelines for future research.

Examining Career Transitions during Mid-Adulthood through the Lens of Bioecological and Microdevelopmental Research

Examining Career Transitions during Mid-Adulthood through the Lens of Bioecological and Microdevelopmental Research

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Davis, Joe Edd
Description: Using hierarchical multiple linear regression, this study examined the predictive relationship between micro-career transitions and career related outcomes and how those relationships were moderated by equilibration style. Participants (n = 177) answered an online survey which included a variety of measures for control, predictor, moderator, and outcome criterion (i.e., demographic descriptors, Instrumentality, Openness, Job Insecurity, Social Support Satisfaction, Microtransitions, Equilibration Style, Job Satisfaction, Job Burnout, Life Dissatisfaction, and Career Optimism). Research questions addressed the nature of micro-career transitions (e.g., frequencies, average stress ratings, category types), their predictive relationship with job and career outcomes, and the moderating role of Identity Styles on that relationship. Micro-career transitions were described according to responses for the research sample (n = 638). Significant effects were discovered between microtransitions and career outcomes (p < .05 and .01). Equilibration styles were also established as having a moderating effect on the predictive relationship between microtransitions and career outcomes (p < .05 and .01). Interaction terms were decomposed to examine the direction of significant moderating effects. In all cases where interaction terms were significant, moderators enhanced the negative predictive relationship between microtransitions and career outcomes.

The role of resilience in mediating outcomes associated with grandparents raising their grandchildren.

The role of resilience in mediating outcomes associated with grandparents raising their grandchildren.

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Davis, Shanna R.
Description: The occurrence of custodial grandparents is increasing greatly. These grandparents face added stress and many adversities that arise from caregiving. Findings of current research tends to be mixed on the effects of grandparents raising grandchildren experience. Much research concludes that grandparent caregivers experience negative declines in overall health and well-being, while other research points out that the caregiving role may actually be a positive experience for the grandparent. The current study hypothesizes that mixed research may be a result of varying levels of resilience in the custodial grandparent population. The model proposed in this study looks at resilience as a mediator between several variables that effect custodial grandparenting. The current sample consisted of 239 custodial grandparents. A regression/correlation analysis was conducted on the data, and it was found that resilience levels were significant in mediating the effects of grandparent caregiving.

Self Blame in Sexual Assault Survivors and Attributions to Other Sexual Assault Survivors

Self Blame in Sexual Assault Survivors and Attributions to Other Sexual Assault Survivors

Date: December 2009
Creator: Pepper, Sarah E.
Description: Previous research indicates that survivors of sexual assault often blame themselves for the assault. Research has also shown that people blame the perpetrator in some situations and the survivor in other situations involving sexual assault. The purpose of this study was to discover if survivors of sexual assault who blame themselves tend to blame other survivors (survivor blame) in situations different from their own. Another purpose was to assess whether or not sexual assault survivors who do not blame themselves for their attack tend to blame other survivors. The participants' attributional style was also assessed in order to understand the relations between self-blame and survivor blame in situations involving sexual assault. Findings indicated that certain types of attributional style are related to self-blame in sexual assault survivors and blame toward sexual assault survivors depicted in vignettes. This indicates that attributional style may have important implications in the clinical setting to aid sexual assault survivors who experience self-blame, as well in educating society about sexual assault and the ultimate responsibility of perpetrators.

Antecedents of commitment to and support of a proposed change initiative in a Southern Baptist congregation.

Antecedents of commitment to and support of a proposed change initiative in a Southern Baptist congregation.

Date: August 2009
Creator: Lee, Audra
Description: This study extends research findings directed at a micro-focus of change by assessing individual organizational members' perspectives and psychological constructs influencing change efforts by an organization. The change initiative in question regards the construction of a new facility and subsequent relocation to said facility. Moral commitment to the organization (negative), change initiative's fit with organizational vision, and social influence significantly contributed to variance in members' affective commitment to change. Trust in leadership and normative commitment to the organization (NCO) significantly contributed to variance in members' normative commitment to change. Continuance commitment to the organization and participation (negative) significantly contributed to variance in members' continuance commitment to change. NCO, change initiative's fit with organizational vision, and participation significantly contributed to variance in support of the proposed change initiative. Affective commitment to the organization (negative), NCO (negative), trust in leadership (negative), and disruption of influence significantly contributed to variance in members' intent to leave the organization.

Psychological Stress Reactivity and Recovery: The Role of Cognitive Appraisals, Ethnicity and Sex

Psychological Stress Reactivity and Recovery: The Role of Cognitive Appraisals, Ethnicity and Sex

Date: December 2009
Creator: Malhotra, Damini
Description: The aim of this research was to investigate the role of sex, ethnicity and cognitive appraisals, separately and in combination, on the physiological stress response. One hundred and eight undergraduate students from two North Texas universities participated in the study. They were subjected to a laboratory stressor and heart rate, peripheral temperature and cortisol levels were measured pre-, during-, and post- stressor. Perceived stress and cognitive appraisals were measured via self-report. Multivariate analysis of variance tests were conducted to analyze the main and interaction effects during baseline, reactivity and post-stress recovery. Results indicated some significant main effects for sex and ethnicity but no consistent pattern of results or interactions among variables were revealed. The study's implications and areas of future research are discussed.

A Longitudinal Examination of Factors Associated with Custodial Grandparenting: A Test of Moderated Mediation

A Longitudinal Examination of Factors Associated with Custodial Grandparenting: A Test of Moderated Mediation

Date: December 2009
Creator: Moske, Amanda Kay
Description: The purpose of this study was to explore the following relationships: (a) how moderating factors (gender, age, ethnicity, social support, marital status, reason for role assumption and number of grandchildren in the home) can influence the mediating role of resiliency, and (b) how resiliency may mediate the negative effects of raising grandchildren (role demands, life disruptions, and difficulties with grandchildren) on grandparent adjustment over time. Resiliency was hypothesized to have the greatest effect on custodial grandparents who experienced the most stress (i.e., older, single, Caucasian males lacking social support and raising more than one grandchild). Mediation was assessed using structural equation modeling. Results indicated resilience mediated the relationship between role assumptions (i.e., role demands and life disruptions) and grandparent adjustment; however, resilience did not mediate the relationship between grandchild characteristics and grandparent adjustment. Due to the small number of custodial grandfathers (n = 14), non-married grandparents (n = 29), non-Caucasian grandparents (n = 10), the small number of grandparents who assumed the custodial role for less ambiguous reasons (n = 24), and the number of custodial grandparents with more than one grandchild residing in the home (n = 29) participating within the study, hierarchical multiple regressions were only conducted to ...

Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans

Perceived Racial Discrimination and Psychiatric Outcomes among Asian Americans

Date: December 2009
Creator: Varghese, Anita
Description: The present study related generational status, family dynamics, and perceptions of racial discrimination (PRD) to acute psychiatric outcomes among a nationally representative Asian American sample (N = 2095), using data from the National Latino and Asian American Study (NLAAS). High self-reports of PRD were correlated with endorsement of clinical depression and suicidality as predicted. Regression analyses suggested that high PRD, low family cohesion, and high family conflict served as significant predictors of poor mental health independently, but moderator hypotheses predicting the interaction of these factors were not supported. Clinical and research implications are provided.
