Adolescent self-mutilating behaviors: Experiential avoidance coupled with imitation?

Adolescent self-mutilating behaviors: Experiential avoidance coupled with imitation?

Date: August 2008
Creator: Howe-Martin, Laura S.
Description: Repetitive self-mutilation (RSM) has become increasingly prevalent among adolescents. Empirical research has pinpointed several correlates of this behavior, but the initiation and maintenance of RSM among adolescents are not well understood. The experiential avoidance model (EAM) proposes that self-mutilation is a behavior that allows for the avoidance or alteration of unwanted internal experiences, and that it is negatively reinforced with repetition. The current study explored the usefulness of the EAM as an explanatory theory for adolescent RSM, with the additional incorporation of issues of social context. Adolescents (N = 211) from three school-based samples completed self-report questionnaires. One-third of students reported at least one incident of purposeful, non-suicidal self-mutilation and 16% had engaged in self-mutilation repeatedly within the past 6 months. Both regression and group analyses indicated that adolescents who engage in RSM report greater psychological distress, a greater incidence of functionally equivalent behaviors, and greater exposure to self-mutilation among peers and/or in the media, when compared to their counterparts who have not engaged in RSM. Suicidal ideation/behaviors were consistently the strongest predictors of current self-mutilation behaviors. Clinical implications, limitations, and suggestions for future research are discussed.

Adult attachment and posttraumatic growth in sexual assault survivors.

Adult attachment and posttraumatic growth in sexual assault survivors.

Date: August 2008
Creator: Gwynn, Stacy Roddy
Description: Posttraumatic growth, defined as positive psychological changes in the aftermath of adversity and suffering, is a relatively recent focus in psychological research. The addition of this concept to the literature has provided a new, more resiliency-based framework through which to view survivors of various forms of trauma. Despite estimates that over half of all sexual assaults are not reported to the authorities, current crime statistics indicate that 1 in 4 women are sexually assaulted in their lifetime (Campbell & Wasco, 2005). Given the large percentage of the population that is impacted by sexual assault, it is essential that professionals better understand the factors that influence the successful healing and growth that can occur post-trauma. The purpose of this study was to further expand the literature on posttraumatic growth in sexual assault survivors by considering this phenomenon through the lens of attachment theory. Specifically, this study tested a proposed model of the inter-relationships among subjective and objective perceptions of threat during the sexual assault, adult romantic attachment, and posttraumatic growth. It was hypothesized that adult romantic attachment and parent-child attachment would mediate the relationship between subjective, or perceived threat, defined as the victim's perception of life threat, and objective threat, defined ...

Affective and cognitive components of job satisfaction: Scale development and initial validiation.

Affective and cognitive components of job satisfaction: Scale development and initial validiation.

Date: August 2008
Creator: Tekell, Jeremy Kyle
Description: Job satisfaction is one of the most commonly studied variables in the organizational literature. It is related to a multitude of employee-relevant variables including but not limited to performance, organizational commitment, and intent to quit. This study examined two new instruments measuring the components of affect and cognition as they relate to job satisfaction. It further proposed including an evaluative (or true attitudinal) component to improve the prediction of job satisfaction. Results provide some evidence of both two and three factor structures of affect and cognition. This study found minimal support for the inclusion of evaluation in the measurement of job satisfaction. Affect was found to be the single best predictor of job satisfaction, regardless of the satisfaction measure used. Further development is needed to define the factor structures of affect and cognition as well as the role of these factors and evaluation in the prediction of job satisfaction.

Agreement between self and other ratings in multi-rater tools: Performance, alternative measures, and importance.

Agreement between self and other ratings in multi-rater tools: Performance, alternative measures, and importance.

Date: August 2008
Creator: Grahek, Myranda
Description: Multi-rater tools also referred to as 360-degree feedback tools, are frequently used in addition to traditional supervisory appraisals due to sources (i.e., supervisor, peer, direct report) unique perspectives and opportunities to view different aspects of job performance. Research has found that the differences among sources are most prevalent between self and other ratings, and the direction of agreement is related to overall job performance. Research has typically focused on one form of agreement, the direction of an individual's self-ratings compared to others' ratings. The current study expanded on past research on rater agreement using a data set (n = 215) consisting of multi-rater data for professionals participating in a leadership development process. The study examined the ability to predict job performance with three different measures of self-other agreement (i.e., difference between overall mean scores (difference), mean absolute difference across items (difference), and mean correlation across items (similarity)). The study also examined how the relationships may differ across performance dimensions. The final purpose was to explore how the importance of the performance dimensions, as rated by the participant, may moderate the relationship between self-other agreement and job performance. Partial support for study's hypotheses was found. The direction and difference measures of ...

Association between folate, vitamin B12 and cognitive performance in demented elderly.

Association between folate, vitamin B12 and cognitive performance in demented elderly.

Date: August 2008
Creator: Serova, Svetlana
Description: Dementia is prevalent among elderly people. As the world population ages, it is projected that the number of people affected by dementia may triple in the next 50 years. Over the last two decades, research has focused on identifying potentially modifiable risk factors in development and progression of dementia, such as vitamin B12 and folate. Results concerning the effects of low folate and vitamin B12 on cognitive performance are mixed. The main objective of the present study was to investigate the effects of vitamin deficiency on cognitive functioning in a clinical sample of elderly individuals with cognitive problems using a comprehensive neuropsychological assessment. A retrospective chart-review was performed on the 102 records of patients from the Geriatrics Clinic at the University of North Texas Health Science Center who presented with cognitive deficits. Charts were reviewed to obtain data on vitamin supplementation, vitamin status, history of chronic conditions and other biochemical data. The available database was used to obtain data on neuropsychological assessment. The study demonstrated mild association between vitamin B12 and folate status and cognitive deficits. There appeared to be a higher cut-off level that is above the traditionally used levels for vitamin B12 and folate deficiency concentrations at which ...

Correlates of a Past Behavior Interview for the Business Unit Leader: Experience, Motivation, Personality and Cognitive Ability

Correlates of a Past Behavior Interview for the Business Unit Leader: Experience, Motivation, Personality and Cognitive Ability

Date: August 2008
Creator: Conner, Lane A.
Description: This research evaluates the relationship between various individual differences constructs and performance on a past behavior interview (PBI)-one of the most popular forms of personnel selection interviews used today-within a sample of business unit leader level incumbents and applicants from organizations across the United States. Correlation analysis is conducted on the relationship between overall performance on a PBI and four work-related constructs: Experience, Motivation, Personality, and Cognitive Ability. The existing literature on PBIs and the four independent variables is critically reviewed. As limited research has been conducted on the influence of Experience and Motivation on PBI performance, this study makes unique contributions to the literature regarding impact of these two constructs. The major hypotheses stated that Experience and Motivation would yield significant, positive correlations with PBI performance while Personality and Cognitive Ability would not be significantly correlated with PBIs. Results partially supported the hypotheses-Experience, Motivation, and Personality were significantly related to overall PBI score, while Cognitive Ability was not. Implications for the findings as well as suggestions for future research are discussed.

The effectiveness of the Geriatric Depression Scale to distinguish apathy from depression in Alzheimer's disease and related dementias.

The effectiveness of the Geriatric Depression Scale to distinguish apathy from depression in Alzheimer's disease and related dementias.

Date: August 2008
Creator: Davis, Tommy E., Jr.
Description: Early detection of Alzheimer's disease (AD) and related dementias in the elderly is critical for improving treatment methods and is a necessary component for improving public health interventions. One of the earliest and most common behavioral syndromes of AD is apathy and is associated with executive dysfunction. Apathy in AD is often misdiagnosed as depression due to an overlap in symptoms. Studies that have found depression to be associated with executive dysfunction have not always controlled for the presence of apathy. The Geriatric Depression Scale (GDS) is a widely used instrument designed to assess depression in the elderly. This study utilized the GDS and a set of standard neuropsychological instruments to investigate the relationship between apathy, depression, and executive functions in individuals with AD and related dementias. The first objective of this study was to determine if apathy has a greater impact on executive functions compared to depression in AD and related dementias. The second objective was to determine the effectiveness of the GDS as a screen for apathy. The results of the analyses did not support the hypotheses. However, exploratory analyses suggested a possible non-linear relationship with apathy and various levels of dementia severity. Exploratory analysis also suggested mean ...

The effects of sequential versus referential montage neurofeedback amplitude training on QEEG measures of phase and coherence.

The effects of sequential versus referential montage neurofeedback amplitude training on QEEG measures of phase and coherence.

Date: August 2008
Creator: Ramezani, Amir
Description: An important clinical research question to be answered in the field of neurofeedback (NF) is whether amplitude training affects connectivity between cortical sites. This study hypothesizes that, following NF amplitude training, there will be a difference in QEEG coherence and phase measures between NF training done using referential montages and using sequential montages. The study examined case files of 16 adult clients from the University of North Texas Neurotherapy Lab who had received NF training that consisted of either referential or sequential placement amplitude training (no coherence training) and who received both pre- and post- treatment QEEGs. Sixty-eight percent of the cases consisted of referential placements, while 34% of the cases consisted of sequential placements. All frontal site phase and coherence abnormal z-scores at pre-treatment were converted to deviation scores and compared by general linear model analysis of variance to post-treatment deviation scores. Effect size r-values and eta square values indicate that differences between referential and sequential electrode placements after NF amplitude training are moderately high. This study shows that referential placements tend to increase phase scores and decrease coherence scores, while sequential placements tend to decrease phase scores and increase coherence scores.

Efficacy of neurofeedback for children with histories of abuse and neglect: Pilot study and meta-analytic comparison to other treatments.

Efficacy of neurofeedback for children with histories of abuse and neglect: Pilot study and meta-analytic comparison to other treatments.

Date: August 2008
Creator: Huang-Storms, Lark
Description: This two-part study investigates the effectiveness of neurofeedback training for reducing behavioral problems commonly observed in abused/neglected children, and compares its efficacy to other treatment interventions with this population. Neuro-developmental sequelae of early relationship trauma are explored as an etiological framework for understanding disturbed affect-regulation, which appears central to the behavioral and emotional difficulties commonly experienced by this pediatric population. It is suggested that neurofeedback teaches children to self-regulate brain rhythmicity mechanisms, which in turn affects global improvements in behavior and mood. The pilot study utilizes records of 20 children removed from their biological homes by Child Protective Services. Children were assessed prior to treatment using the Child Behavior Checklist (CBCL) and the Test of Variables of Attention (TOVA), and again after 30 sessions of individualized, qEEG-guided neurofeedback training. A t-test analysis of pre- and post-scores was computed, and indicated significant improvements following treatment. A meta-analysis of existing literature on treatment interventions with abused/neglected children provides individual and aggregate effect sizes for 33 outcome studies with this clinical population, and contextualizes the results of the present pilot study within other empirically validated treatment modalities. Establishment of an overall effect size for treatment for this pediatric population provides a needed method ...

An empirical investigation of the influence of age, gender, and occupational level on stress perceptions, job satisfaction, organizational commitment, and turnover.

An empirical investigation of the influence of age, gender, and occupational level on stress perceptions, job satisfaction, organizational commitment, and turnover.

Date: May 2008
Creator: Cordas, Jon D.
Description: This study investigated relationships of age, gender, and supervisor level with job satisfaction, organizational commitment, stress perception, and turnover intention. The demographics were hypothesized to moderate the stress-satisfaction and commitment-turnover relationships. Hypotheses were tested using both parametric and non-parametric bootstrap methods. Subjects were taken from a national survey of 2,663 public sector IT workers. Missing data were imputed using NORM software. Ordinary least squares (OLS) regression indicated a significant direct effect from all main variables and covariates, except for age on turnover intent. No mediating effects were found. Age-Commitment was the only significant higher order modifier relationship, although Gender-Commitment explained substantial variance. LMG statistic results enabled the predictors to be rank ordered with confidence intervals. Best subset bootstrap regression explored all possible predictor orders to confirm which model explained the most variance. The original model and predictor sequence were confirmed. The bootstrap AIC statistic provided a model which maximized explained variance while optimizing parsimony. Since only age had a mediating effect, Hypotheses 1 and 2 were not supported. All other hypotheses were partially confirmed.
