Trauma Responses, Abuse History, and Exposure to Violence as Risk Factors in Adolescent Sex and Non-Sex Offenders

Access: Use of this item is restricted to the UNT Community
Several risk factors have been identified for adolescent sex offenders and non-sex offenders. Such risk factors include physical and/or sexual abuse, and exposure to community and/or domestic violence. Additionally, the presence of disinhibitive factors, such as substance use and exposure to violent or pornographic media are also commonly reported in the backgrounds of both sex and non-sex offenders. Similarly, adolescent offenders have reported traumatic reactions to environmental factors such as abuse and violence. Similarities in exposure to the risk and disinhibitive factors described above between adolescent sex and non-sex offenders do not provide an explanation for why some adolescents commit sex offenses, whereas other adolescent offenders do not. This study investigated the discriminative ability of traumatic reactions as a risk factor between male adolescent sex and non-sex offenders. The inclusion of traumatic reactions increased the accuracy of risk factors distinguishing between sex and non-sex offenders. Thus, not only the presence of risk factors, but also the adolescent's reaction to the risk factors, are important predictors of whether he will commit a sexual offense.

Narcissistic traits and parenting style: A closer look at maladaptive parenting through parent-child observations, parent self-report, and child self-report.

Access: Use of this item is restricted to the UNT Community
The thrust of this paper was two-fold, 1) to confirm a 2-factor model of narcissism in women, and 2) to examine the relationship between narcissistic traits in mothers and several variables associated with parenting efficacy. Participants included 193 mother-child dyads. A 2-factor model of narcissism was confirmed in the present sample of mothers, suggesting that narcissistic traits in women may be manifested in distinct Overt and Covert forms. Contrary to expectations, Covert Narcissistic traits in mothers did not significantly correlate with observed parenting behaviors on the PCIA, including Positive Personal Comments (PPC) towards children, Negative Personal Comments (NPC), and Parental Nurturance. However, children's self-reported maternal rejection on the C-PARQ correlated positively with Covert Narcissistic traits in mothers, as did mother's self-reported dysfunctional parenting attitudes on the AAPI-2. Narcissistic traits in mothers correlated most strongly with risk of child physical abuse on the CAPI (r = .70). Results are also presented for the Overt Narcissism factor, which proved to be less stable as a factor. Overall, results emphasize the need for a more comprehensive understanding of narcissism for women, given its potential Implications for children's healthy development and parenting interventions.

Treatment efficacy in a chronic pain population: Pre- to post-treatment.

Access: Use of this item is restricted to the UNT Community
The purpose of the current study was to investigate the effects of a multidisciplinary pain management program on five measures of subjective psychosocial factors. Ninety-five participants in the comprehensive multidisciplinary treatment group and the standard medical intervention control group were surveyed about various psychosocial factors using Axis II of the West Haven - Yale Multidimensional Pain Inventory (MPI), pre- to post-treatment. It was hypothesized that post-treatment levels would be significantly lower than pre-treatment levels for all five psychosocial variables. Additionally, gender and ethnicity variables were examined. Based on preliminary analyses indicating pre-treatment differences between the experimental and control group, five 2 x 2 x 3 analyses of covariances (ANCOVAs) were used to examine the above hypotheses. Results indicated significant differences between the treatment conditions on measures of control, with the comprehensive group feeling more in control than the standard group at post-treatment. No other significant main effects for treatment condition were found on the measures of pain severity, interference with daily activities, negative mood, or social support. However, a significant gender main effect was found for social support at post-treatment, with females reporting more social support than males. A significant gender x ethnicity interaction was also found for post-treatment control, …

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Access: Use of this item is restricted to the UNT Community
Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results indicate that overall methodological rigor is not a significant predictor of organizational change outcomes; however, several individual rigor criteria exhibit predictive power. Implementation quality is a significant predictor of organizational outcomes, but in a negative direction.

Organizational Change Development Interventions: Are Multiple Interventions Useful?

Access: Use of this item is restricted to the UNT Community
The effects of multiple interventions in organizational development change were studied in a comprehensive meta-analytic review. Thirteen organizational interventions were assessed on five outcome variables based upon previous research of six major meta-analytic reviews. Findings based on 138 studies indicated that there were no significant effects of multiple interventions on positive organizational change as opposed to individually implemented interventions. The findings are not congruent with previous findings of organizational development change, and possible issues surrounding these differences are discussed.

Organizational development: A comparison of individual and organizational level change.

Access: Use of this item is restricted to the UNT Community
Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

Perceived Change in Behavior Associated with Peer Feedback in Work Teams

Access: Use of this item is restricted to the UNT Community
This study investigated if the use of a team feedback system resulted in peers perceiving a change in behavior. Personality variables such as conscientiousness, agreeableness, and extraversion were examined as possible moderators. Self-ratings and peer ratings were collected from 164 individuals through the use of the Center for Collaborative Organizations' Team Feedback System. Using polynomial regression, it was determined that time 1 peer ratings predicted behavior change and the combination of conscientiousness variables moderated peer perceived behavior change.

Positive and Negative Affect: Differential Impact of Optimism, Pessimism, and Coping in People Living with HIV/AIDS

Access: Use of this item is restricted to the UNT Community
People living with HIV/AIDS (PLH) struggle with depression. Recent research suggests that depression affects medical regimen adherence, disease progression, and risky sexual behaviors. The present study uses a stress and coping theory viewing HIV-related stigma and physical symptoms as stressors in PLH. Results suggest whereas symptoms and stigma consistently predict negative affect, positive affect, and overall depression, the role of optimism, pessimism, active coping, denial, and behavioral disengagement is not as clear. Pessimism and denial predict negative affect and depression. Optimism and behavioral disengagement predict depression and positive affect. Active coping only predicts positive affect. Focusing on positive and negative affect as distinct components that contribute to overall depression may help researchers develop interventions more effectively.

Treatment Effects Related to EEG-Biofeedback for Crack Cocaine Dependency: Changes in Personality and Attentional Variables

Access: Use of this item is restricted to the UNT Community
EEG biofeedback (neurotherapy) has been demonstrated as effective in the treatment of alcoholism, as evidenced by Peniston and Kulkosky's research efforts. These neurotherapy pioneers evaluated the efficacy of alpha-theta brain wave biofeedback as a treatment for chronic alcohol abuse, citing 80% abstinence rates as measured by improvements in psychopathology, serum beta endorphin levels, and long-term alcohol abstinence. Most research with alpha-theta EEG biofeedback has addressed alcohol addiction. Cocaine is now considered to be the most common drug problem of patients entering treatment for drug abuse. To date, only one controlled study has been published that researched alpha-theta neurofeedback in the treatment of "crack" cocaine addiction. The present study was an extension of a 4-year EEG-biofeedback treatment outcome project underway at a faith-based homeless mission in Houston, Texas, with male "crack" cocaine addicts. Changes in personality, attention, and impulsivity were measured following 30 sessions of a non-individualized EEG -biofeedback protocol. Experimental subjects received a variant of the Peniston-Kulkosky alpha-theta protocol for 30 sessions while controls received all elements of the experimental protocol except the EEG biofeedback. Assessment measures included the MMPI-2 and the IVA. Although experimental subjects showed greater mean improvement on most MMPI basic scales and all IVA Attention related …

Depression, Activities of Daily Living, and Retirement

Access: Use of this item is restricted to the UNT Community
Depression is a common clinical and subclinical psychiatric disorder in the middle-age to older adult population. This study examined the relationship between depression and activities of daily living (ADLs) in middle-age to older adults. This study examined longitudinal data from the 1998, wave 4, and 2000, wave 5, of the Health and Retirement Study (HRS), a National Panel Study sponsored by the National Institute on Aging. A negative cross-sectional and longitudinal relationship between higher ADL scores and depression was hypothesized. A goal of the present study was to determine the temporal precedence of these two constructs using a cross-lag panel design to first examine the cross-sectional relationship between ADLs and depression at time-one and at time-two, and then the time-one to time-two longitudinal relationships to examine temporal precedence possible causal relationships. Finally, differences in these correlational relationships by retirement status and then by marital status were tested. There were several interesting findings, including those who were retired in both 1998 and 2000 reported fewer ADLs (i.e., worse functioning), but also reported better health than those who were working in both 1998 and 2000. Similarly, those people who were not married in both 1998 and 2000 reported fewer ADLs but better …

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization

Access: Use of this item is restricted to the UNT Community
In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.

Longitudinal Study of the Impact of Performance Appraisals in Organizations

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to determine the effectiveness of and the subjects' overall satisfaction with the implementation of an internally created performance appraisal system. The system was implemented at a major technology consulting firm in the US. The subjects of this study were manager level employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of managers' responses to six key questions in the Career Development category were analyzed. Managers' perceptions of their contribution to the firm, their understanding of what career paths are available to them, their understanding of the requirements for promotion, as well as their overall satisfaction with the implementation of the performance appraisal system were captured by this survey. Trend analysis indicates that managers at the firm perceived their career path knowledge improved and their understanding of promotion criteria improved as a result of the implementation. Overall satisfaction with the implementation did not improve enough to site confidence in managers' perceptions for the period immediately after the implementation; managers' responses to the actual implementation were disagreeable to neutral. Managers did not feel their impact on the organization improved as …

The roles of intimacy motivation and mutuality in relation to depression and interpersonal problems.

Access: Use of this item is restricted to the UNT Community
There is extensive research on depression and interpersonal problems, but research has not addressed these concepts in relation to mutuality and human motivation. Therefore, the purpose of the current study is to consider the associations between intimacy motivation and mutuality of closest relationships and how, when combined, the two connect to depressive experiences and the occurrence of interpersonal problems. Of the 7 original hypotheses suggested, 2 were supported while 5 were not. Perhaps the most interesting finding, and certainly the one with the most practical application, came from the two supported hypotheses. The analyses show that interpersonal problem subtypes are associated with specific depressive subtypes by operationalizing the demand/withdraw pattern of conflict. The exploratory findings also suggest a possible mediation of gender and depression by mutuality.

Employee empowerment: Relationships between location in the hierarchy, span of control, and industry type on perceptions of empowerment.

Access: Use of this item is restricted to the UNT Community
The current study seeks to examine the relationships between perceptions of employee empowerment and perceptions of leadership, span of control, and industry type. Participants were gathered from an archival source employing a high school alumni e-mail group (n = 361) and a survey from 9 organizations (n = 647) and combined into a larger sample (n = 1008). The participants took Bodner's (2005) Assessment of Employee Empowerment and Assessment of Empowering Leadership instruments. Support was found to suggest that people report being less empowered than they believe that top management would report about them. Also, participants reported that their leader was less empowering than they believed top management would report about the leader. Span of control was found to impact perceptions of empowerment. Production workers reported feeling more empowered than workers in service industries. Participants did not report that leaders were more empowering if they were higher in the hierarchy (executive) than lower levels (coach, employee). Also, a respondent's position did not affect the relationship between job type and feelings of empowerment. This study suggests that the organizational design (span of control) and industry type may affect empowerment initiatives, while lower levels of the organization may view empowerment much differently …

Influence of executive function on medication adherence in neurologically impaired and non-impaired elderly.

Access: Use of this item is restricted to the UNT Community
Medication non-compliance has become one of the most prevalent reasons for hospitalization and doctor's visits by the elderly. As the elderly population is more likely to have decreased cognitive abilities, it is suggested that neuropsychological factors, especially executive function, are more influential in medication non-compliance than once thought. This study looked at executive function performance on a traditional battery of neuropsychological tests, self-report of perceived ability to perform executive function tasks, and the newly developed Pillbox Test, a performance based IADL measure. The Pillbox Test is designed to replicate a type of medication-management specific IADL as a means to asses executive function. Standard executive function measures only tap a portion of executive function, but it is believed that the Pillbox Test incorporates all four theoretical domains of executive function. The multiple measures of executive function performance were compared in three prevalent subgroups of the elderly population (mixed neurological group, cardiac medical-control group, and healthy community-control group). Results found significant differences, where the community-control and cardiac groups outperformed the mixed neurological group on the large majority of executive function tasks. Smaller differences were also noted between the community-control and cardiac groups and between the cardiac and mixed neurological groups. Together, these …

Pathophysiology and Racial/Ethnic Disparities in the Progression of Metabolic Syndrome

Access: Use of this item is restricted to the UNT Community
Disparities exist in the U.S. between the health status of African American and Hispanic individuals and the health status of non-Hispanic Caucasian individuals across all age groups. Those minority individuals age 55 and over are more likely to suffer from specific health disparities in areas such as diabetes, heart disease, and cancer than their white majority counterparts. Among the most common chronic disorders experienced within this age group are obesity, type II diabetes and cardiovascular disease, all three of which collectively form what has recently become known as metabolic syndrome. As of 2004, metabolic syndrome is diagnosable once criteria are clinically significant for a variety of different risk factors designated by the World Health Organization. However, like many syndromes these criteria are not stable across individuals, and leaves variability between individuals being diagnosed. It has been seen that each of the above mentioned racial/ethnic groups experience the individual risk factors at disproportionate rates, making it plausible that metabolic syndrome could be experienced in distinctly different ways depending upon racial/ethnic background. Using two nationally representative data sets, it is first largely evident that African American and Hispanic individuals are reaching higher peak rates of diabetes and cardiovascular disease much earlier in …

Adolescent Insomnia as a Predictor of Early Adulthood Outcomes

Access: Use of this item is restricted to the UNT Community
Recent research found insomnia is a risk factor for psychiatric disorders in adults. To see if the same would be true in adolescents, the current study re-analyzed data from a national longitudinal study collected by ADDHealth that evaluated health behaviors in 4552 adolescents (mean age 14.9 years [SD 1.7]) at baseline and again 7-8 years later (n = 3489) during young adulthood. Insomnia was reported by 9.2% of the adolescents. Cross-sectionally, adolescent insomnia was associated with alcohol, cannabis, non-cannabis drugs, and tobacco use, and depression after controlling for gender and ethnicity. Prospectively, adolescent insomnia was a significant risk factor for depression diagnosis, suicidal ideation, and the use of depression and stress prescription medications in young adulthood after controlling for gender, ethnicity, and significant baseline variable. In addition, a trend was noted for suicidal attempts.

Neuromotor and Neurocognitive Functioning in the Prediction of Cognition, Behavior Problems, and Symptoms at Two-year Follow-up in Youth with Schizotypal Personality Disorder

Access: Use of this item is restricted to the UNT Community
Individuals diagnosed with schizotypal personality disorder (SPD) exhibit patterns of cognitive deficits, neuromotor disturbances, and behavior problems similar to individuals with schizophrenia, and thus SPD is thought to represent one point on the continuum of schizophrenia spectrum disorders (SSDs). Deficits in behavior, cognition, and motor functioning have been implicated as childhood precursors of SSDs and appear to also vary as a function of gender and family history of psychopathology. As such, studies of youth may help in further identification of individuals at risk for SSDs. The current study examined the prospective associations between problem behaviors, neuromotor and neurocognitive functioning, as well as SSD symptoms, at baseline and 2-year follow-up in youth meeting criteria for SPD, other personality disorders, or healthy controls. The neuromotor and neurocognitive measures were able to significantly predict SSD symptoms and behavior problems above and beyond baseline predictors. Overall, the findings provide further support for the role of subcortical motor centers operating together with prefrontal cortical areas in the regulation of higher-order cognitive functioning and in producing the psychiatric features of SSDs. Significant correlations between gender, family history of schizophrenia, and history of head injury with symptoms, behavior, cognition, and motor functioning were also found and highlight …

The Effect of Trauma Experiences and PTSD Severity on Positive Memory Recall and Memory Phenomenology

Access: Use of this item is restricted to the UNT Community
Positive memories play an important role in the etiology and maintenance of posttraumatic stress disorder (PTSD). Additionally, there are potential clinical benefits of recalling positive memories on affect, cognitions, and behaviors. However, most research/clinical work has focused on the role of traumatic memories in PTSD's symptomatology and treatment. The current study examined positive memory recall difficulties and positive memory phenomenology among 185 trauma-exposed individuals with varying PTSD severity. Participants completed the Life Events Checklist for DSM-5, PTSD Checklist for DSM-5, Autobiographical Memory Test, Memory Experiences Questionnaire – Short Form, Ruminative Thought Style Questionnaire, Difficulties in Emotional Regulation Scale – Brief 16-Item Version, Difficulties in Emotional Regulation Scale – Positive Emotions, the Positive Affect subscale of the Affective Control Scale, and two items from the Pittsburg Sleep Quality Index. Results showed that (1) greater PTSD severity was a marginally significant predictor of fewer recalled positive memories; (2) greater positive emotional dysregulation predicted fewer recalled positive memories controlling for PTSD severity; and (3) increasing PTSD severity predicted more negative valence, less vividness, less coherence, less accessibility, less clear time perspective, fewer sensory details, and greater distancing ratings of the recalled positive memory, controlling for sleep quantity/quality. Such findings add to the PTSD-positive …

Independence of Mania and Depression across 4 Years in Bipolar Disorder

Access: Use of this item is restricted to the UNT Community
If mania and depression are part of the same pathological processes, one would predict that episodes of one prospectively increase the odds of episodes of the other. The aim of the present study was to test this hypothesis. For comparison purposes, their relationship was contrasted to the relationship between mania and periods of psychosis. Exploratory analyses also tested the degree to which episodes of each occur with greater frequency over time (i.e., kindling). Participants for the present study came from the Suffolk County Mental Health Project (N = 628), a study of first-admission patients with psychosis. Of these participants, 144 met diagnostic criteria for bipolar I disorder and were analyzed for the current study. Results indicated that mania in a given month predicted depression the following month, even after controlling for other symptoms. The reverse, however, was not the case. Mania and psychosis, in contrast, were found to be robust predictors of one another from month to month. Effects were not due to treatment or demographic differences. These findings provide evidence that mania and depression are weakly related. In contrast, mania and psychosis are more closely linked. Findings are consistent with suggestions that psychiatric nosology regroup mania more closely with …

Insomnia and Cognitive Performance: A Systematic Review and Meta-Analysis

Access: Use of this item is restricted to the UNT Community
Daytime cognitive performance and sleep/wake cycles are strongly interrelated, and cognitive dysfunction has been extensively investigated in relation to insomnia. However, methods and outcomes vary widely by study, making comparison difficult without more systematic evaluation. Review of the literature reveals discrepant findings for the relationship between both subjective and objective measures of cognitive performance and insomnia. The current meta-analysis included 42 studies investigating the relationship between insomnia and cognitive performance. Results confirmed the discrepant nature of previous findings and suggest that type of cognitive performance (e.g., simple attention, procedural memory, verbal functions) is important to consider when discussing the impact of insomnia. Mixed-effect meta-analysis of aggregate effect sizes suggest impairments in working memory, complex attention, and episodic memory are significantly associated with insomnia. Analysis of the grouped subjective cognitive performance effect size revealed no significant impact of insomnia. Average age and gender makeup of the sample, study quality, and type of insomnia measure (i.e., clinical or diagnostic criteria, validated scale, or single unvalidated item) did not consistently moderate findings. These results confirm the equivocal nature of the relationship between insomnia and cognitive performance. Overall, about 44% of the studies included in the analysis failed to use DSM or ICSD criteria …

Modeling Marijuana Use Willingness and Problems as a Function of Social Rejection and Social Anxiety

Access: Use of this item is restricted to the UNT Community
Marijuana is the second most commonly used substance in the US. A growing literature suggests that socially anxious individuals use marijuana to manage their symptoms in social situations, which may explain why they are also more likely to experience problems. Unfortunately, the majority of the literature is based on research conducted with adult samples or the co-occurrence of diagnoses in adolescent samples. The proposed study sought to test the link between social anxiety (SA) and proxies for ‘real-time' marijuana use behaviors (i.e., use willingness) as well as use-related problems among adolescents. Participants were 69 adolescents (15-17; 55% female) recruited from the community reporting any lifetime marijuana use. Participants were randomly assigned to a novel social rejection or neutral laboratory task and completed measures of SA, marijuana use frequency, and related problems. Consistent with adult findings, main effects of SA and experimental condition on marijuana use willingness were expected to be qualified by an interaction in which the greatest marijuana use willingness would occur among high SA youth post-rejection (H1), SA would be positively related to marijuana use problems (H2), and among adolescents in the rejection condition, marijuana use willingness would be positively correlated with use problems (H3). Only H2 was …

Bipolar Spectrum Traits in Day-to-Day Life: Ecological Momentary Assessment of Reward Sensitivity, Circadian Timing, and Experience of Reward in the Environment

Access: Use of this item is restricted to the UNT Community
The current study examined 236 undergraduate students in a week long twice-per-day ecological momentary assessment exploring the influence of baseline reward sensitivity and interactions between circadian variables (i.e., total sleep time, sleep quality) and daily measures of reward. Though primary study findings did not support reward sensitivity related moderation of sleep-reward pathways, a number of notable findings emerged. We found evidence of specific domains of reward sensitivity (anticipatory reward and reward responsiveness) which are uniquely related to daily experiences of reward. In addition, bidirectional circadian-reward pathways were found between sleep quality and daily rewards which suggests pathways towards reward-related engagement. Evidence also supported interactions between sleep quality and total sleep time on experience of daily reward, further highlighting the complexity of sleep-reward pathways and their relevance to mood symptoms.
