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.

Personality Correlates of Eating Disorder Symptomatology in a Nonclinical Sample of Female Undergraduates

Access: Use of this item is restricted to the UNT Community
Research indicates the existence of an eating disorder continuum. The two-component model of disordered eating suggests that certain personality traits may increase an individual's vulnerability to develop more severe variants of disordered eating symptomatology. The present study investigates pre-clinical elevations on a measure of personality based on the Five-Factor Model (FFM) and pre-clinical elevations on a measure of eating disorder symptomatology in a sample of nonclinical undergraduates. The personality dimensions Neuroticism, Extraversion, and Agreeableness accounted for 7% of the variability in Body Dissatisfaction. Subcomponents comprising the personality dimensions of the FFM as determined by Saucier (1998) (see Appendix A) were analyzed. The Self-Reproach and Intellectual Interests subcomponents were the strongest predictors of Drive for Thinness and Body Dissatisfaction. The subcomponent Sociability was the strongest predictor of Bulimia. Findings present implications for prevention and treatment interventions. Longitudinal studies are needed to determine the temporal directionality of personality and disturbed eating.

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.

Influences of the Mother-Daughter Relationship on Motivations for Sexual Behavior

Access: Use of this item is restricted to the UNT Community
The influences of family relationship variables on motivations for adolescent sexual risk-taking were investigated. Previous research has linked these variables to adolescent sexual behavior, however, the nature of these links has not been specifically examined. Family variables were operationalized as child attachment to mother, parental support of each other, parental conflict strategies, and parental monitoring. Emotional motivations were operationalized as attachment and affiliation needs. The sample consisted of 40 single females ages 18 to22 recruited from a local pregnancy care center. Predictions that parent-child relationship and parental influence would predict emotional motivations for sexual risk-taking were not supported. The variable most highly related to sexual risk-taking, though not included in the model tested, was father's destructive conflict strategies. Theoretical and methodological issues are discussed.

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 …

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, …

Job Embeddedness as a Predictor of Voluntary Turnover: Validation of a New Instrument

Access: Use of this item is restricted to the UNT Community
Voluntary turnover has become a problem for many organizations in today's society. The cost of this turnover reaches beyond organizational impact, but also affects the employees themselves. For this reason, there has been a plethora of research conducted by both academicians and practitioners on the causes and consequences of voluntary turnover. The purpose of this study is to test the validity and generalizability of the job embeddedness model of voluntary turnover to the information technology (IT) industry. The IT field has been plagued with high turnover rates in recent years. In this study, the job embeddedness model (Mitchell et al., 2001) is applied to a population sample consisting of health care information technology employees.

Performance appraisal impact on employee career development and performance: A longitudinal study.

Access: Use of this item is restricted to the UNT Community
The purpose of this study was to determine the effectiveness of the implementation of an internally created performance appraisal system as well as the subjects' overall satisfaction with the implementation. The system was implemented at a major technology consulting firm in the US. The subjects of this study were three levels of 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 employees' responses to three key questions were analyzed. Employees' perceptions of the appraisal feedback aiding increased performance, their belief about the implementation assisting with their career management, satisfaction with the initiative, and their understanding of the requirements for promotion were captured by this survey. Trend analysis indicates that employees at the firm perceived their career path knowledge unimproved, their understanding of promotion criteria unimproved as a result of the implementation. Employees did not indicate overall satisfaction with the implementation and the employee's belief about their skills and abilities utilization did not improve post implementation.

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.

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 …

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 …

The Effect of Punishment Threat on Children's Ability to Resist Temptation to Transgress and Lie

Access: Use of this item is restricted to the UNT Community
Children's response to a resistance-to-temptation (RTT) task was investigated under three punishment threat conditions: negative consequence, removing an anticipated reward, and no explicit punishment. Ninety first and second graders participated in the RTT task and seventy-three parents completed the Behavior Assessment System for Children and the Psychopathy Screening Device. As only 4% of children transgressed, results are unclear. Hypotheses tested using approximations of transgression showed no differences in RTT. Children with temperaments characterized by hyperactivity, impulsivity, attention problems, and conduct problems (HIA-CP) had the highest levels of psychopathic traits compared to all others. In addition, spanked children were rated as having significantly more behavioral problems than non-spanked children. Limitations of the current study and suggestions for future research are discussed.

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.

Comparative Analysis of Chronic Versus Acute Stressors and Their Influence on Distress Consequences at Work

Access: Use of this item is restricted to the UNT Community
Workplace stress has been found to be a causal agent of psychological distress consequences in employees. Chronic stressors have been well researched, in particular, role conflict, role ambiguity, and work overload have been extensively studied. A meta-analysis was conducted in order to aggregate past research to gain a better understanding of the impact these stressors have on the psychological distress consequences of depression, tension/anxiety, somatic complaints, and generalized feelings of stress. Only role ambiguity was found to be a significant contributor to psychological distress, in particular to feelings of depression and stress. In general, however, effect sizes for all three stressors were moderate to large. While chronic stressors have been well researched, acute stressors have been widely overlooked. Since research in this area is limited, the Daily Work Hassles Survey was developed and validated in order to analyze the role daily hassles play in the workplace. The survey yielded two factors, Interpersonal Hassles and Task Hassles. The former of which was found to be significantly related to the distress consequences of depression, tension/anxiety, somatic complaints, and general feelings of stress. The ultimate goal of this project was to compare chronic and acute stressors. Results from the daily hassles study were …

Depression, Religious Behaviors and Social Support as Predictors of Health-Related Quality of Life among HIV Positive Individuals

Access: Use of this item is restricted to the UNT Community
The goal of the current study was to evaluate the ways in which religious behaviors and perceived social support are associated with the relationship between depressive symptoms and health-related quality of life for this group. We hypothesized (1) that religious behaviors moderate the relationship between depressive symptoms and health-related quality of life, (2) perceived social support mediates the relationship between depressive symptoms and health-related quality of life and (3) that religious behaviors moderate the mediational indirect effect of perceived social support in the depression and health-related quality of life relationship. Findings from a sample of 244 HIV-positive individuals provided evidence to support direct, conditional, and indirect effects on the depressive symptoms and health-related quality of life relationship. A discussion of the findings, implications for future research and clinical practice are provided.

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 …

Prevalence of Undiagnosed Dissociative Disorders in an Inpatient Setting

Access: Use of this item is restricted to the UNT Community
This study examined the prevalence of undiagnosed dissociative disorders in a sample of 201 adult patients admitted to a private psychiatric hospital in a major metropolitan city in the south-central United States, over an eight-month period. A screening measure, two blind structured interviews, and a blind clinical interview were employed. The lifetime prevalence of dissociate disorders among the interviewed subjects was 40.8%. More specifically, 7.5% were diagnosed with dissociative identity disorder, 15.4% with dissociative disorder not otherwise specified, 13.4% with dissociative amnesia, and 4.5% with depersonalization disorder. Dissociative fugue was not found in this sample. Cohen's kappa reliability coefficients were computed between the three interview measures, resulting in significant findings for the presence of dissociative identity disorder and dissociative disorder not otherwise specified versus no dissociative disorder. The Cohen's kappa reliability coefficients were as follows: DDIS-DES-T = 0.81; SCID-D-DES-T = 0.76; Clinician-DES-T = 0.74, DDIS-SCID-D = 0.74; DDIS-Clinician = 0.71, and SCID-D-Clinician = 0.56. A meeting was conducted at the end of all subject interviews to discuss discrepant findings between measures. Four additional sub-analyses were performed between dissociative and non-dissociative subjects on DSM-IV variables. Patients diagnosed with a dissociative disorder had higher rates of comorbid major depressive disorder, borderline personality …

The Relationship between Executive and Psychosocial Functioning in Children Treated for a Brain Tumor

Access: Use of this item is restricted to the UNT Community
This study examined the relationship between executive and psychosocial functioning in 45 children and adolescents age 6 to 17 years who had been treated for a brain tumor. Executive functioning deficits can profoundly impact an adult's ability to function successfully in life. The purpose of the study was to evaluate the potential impact of executive functioning deficits on the day-to-day functioning in a pediatric population. The domains of executive functioning assessed included cognitive flexibility, conceptual thinking, sustained attention, and response inhibition. Psychosocial functioning was assessed using both parent and child report. Several significant relationships were found for adolescents ages 15 and older, with effect sizes ranging from medium to large. In particular, cognitive flexibility and conceptual thinking were significantly related to parent report of depression and adaptive functioning. Fewer significant relationships with smaller effect sizes were found for younger children. The results may reflect the developmental emergence of executive functioning abilities and late effects of executive functioning deficits upon psychosocial functioning. The correlational design of this study precludes definitive statements regarding the temporal nature of the relationship. Additional research, including longitudinal research and replicatory studies, will be needed to further investigate the developmental consequences of executive functioning impairment.

Improving Actigraphy Specificity to Better Inform Insomnia Diagnosis and Treatment Decisions

Access: Use of this item is restricted to the UNT Community
Accurate assessment of sleep-wake patterns is important for sleep researchers and clinicians. Actigraphs are low-cost, non-intrusive, wrist-worn activity detectors used to estimate sleep-wake patterns in a natural environment for several nights. Although actigraphy shows good sensitivity (sleep detection), it has consistently demonstrated poor specificity (wakefulness detection while lying in bed relatively motionless). Because insomnia is characterized by wakefulness in bed, actigraphy may not be a valid objective measure of wakefulness for this group. It is possible that refinement of actigraphy software settings for sleep/wake algorithms might improve specificity. The current studies investigated this hypothesis by comparing wake parameters from 48 combinations of actigraphy settings to determine which sleep/wake algorithms best inform insomnia diagnosis and treatment. In the first study, none of the 48 actigraphy setting combinations consistently discriminated between adults with insomnia (n = 69) and non-insomnia (n = 80) on all three wake parameters, and no setting clearly discriminated between groups for the composite variable, total wake time. Similarly, in the second study, no setting combinations consistently discriminated between adults treated for insomnia (n = 18) and controls with untreated insomnia (n = 26) on all three wake parameters. Although two setting combinations discriminated between groups for the composite …

Psychological Well-Being and Family Functioning in Middle Childhood: The Unique Role of Sibling Relational Dynamics

Access: Use of this item is restricted to the UNT Community
The current study examined associations between perceived family functioning, sibling relational dynamics, and individual's self-reported personal adjustment and internalizing problems among 8- to 11-year old children. Path analyses revealed significant direct effects between conflictual family functioning and children's psychological well-being (p < 0.05). Further, sibling conflict was found to indirectly affect these associations. Finally, significant interactions between family functioning and sibling dynamics were found suggesting that congruent relational dynamics at multiple levels of the family system had a cumulative impact on the child's well-being. Findings from the current study highlight the unique contributions of sibling relationships to the family and the child providing evidence for targeting the sibling relationship in clinical interventions and future family research.

Universal Suicide Risk Screening in the Parkland Health and Hospital System: Evaluation of the Parkland Algorithm for Suicide Screening

Access: Use of this item is restricted to the UNT Community
Suicide is a significant public health issue in the US. Despite national and international prioritization since 1996, little definitive progress has been made in terms of identification and intervention in cases of elevated suicide risk. Forty percent of those who died by suicide attended an emergency department within a year of death. Therefore, universal suicide risk screening in emergency departments could prove a vital component to a national suicide prevention strategy. The present study empirically evaluated the universal suicide risk screening program recently implemented at Parkland Health and Hospital System. The sample consisted of patients over 18 years of age (N=333,855; Mage=42.7, 32% male) screened as part of routine clinical care from May 4th, 2015, through November 3rd, 2015. The Parkland Algorithm for Suicide Screening (PASS) is part of a clinical decision support system for responses to Columbia - Suicide Severity Rating Scale Clinical Practice Screener (C-SSRS) items, leading to an automated clinical response via three suicide risk stratification levels: no action for no risk identified, psychiatric social worker assessment for moderate risk identified, and psychiatrist/psychologist interview for high risk identified.

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 …
