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

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

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Besich, John S.
Description: 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.

Measuring change in university counseling center students: Using symptom reduction and satisfaction with services to propose a model for effective outcome research

Measuring change in university counseling center students: Using symptom reduction and satisfaction with services to propose a model for effective outcome research

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Quick, Cynthia L.
Description: Abstract This study proposes a model for meeting increasingly mandated outcome research objectives in a university counseling center setting. It is proposed that counseling centers utilize their existing intake forms, along with an annual satisfaction survey to determine the effectiveness of counseling services. Effectiveness is defined as improvement and measured by the reduction of the symptoms or presenting concerns with which the client initially presented. It also introduces the Relative-Change Index (R-Chi) as an objective way to quantify intra-individual change occurring as a result of therapy. This new mathematical procedure allows for a more meaningful assessment of the client's degree of improvement, relative to their potential for improvement. By re-administering the problem checklist, routinely included as part of the initial paperwork for each client at intake, again post-therapy, it is possible to quantify improvement by measuring the difference in distressing concerns. Additionally, including a subjective, retrospective survey question asking the client to indicate their perceived rate if improvement at follow-up provides construct validity and allows for correlational comparisons with R-Chi. Results suggest that student/client ratings of the degree to which the services they received satisfactorily addressed their presenting concerns were significantly rated to their R-Chi score. This model suggests that ...

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

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

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: Barnett, Michelle L.
Description: 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

Perceived Change in Behavior Associated with Peer Feedback in Work Teams

Access: Use of this item is restricted to the UNT Community.
Date: August 2005
Creator: DeJarnett, Nicole
Description: 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

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.
Date: August 2005
Creator: Ranucci, Melissa B.
Description: 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.

Psychological and Sociodemographic Predictors of Psychological Distress in BRCA1 and BRCA2 Genetic Testing Participants within a Community Based Genetic Screening Program

Psychological and Sociodemographic Predictors of Psychological Distress in BRCA1 and BRCA2 Genetic Testing Participants within a Community Based Genetic Screening Program

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Lesniak, Karen
Description: Mutations in BRCA1 and BRCA2, the first two breast cancer susceptibility genes identified, carry as much as an 85% lifetime risk of developing breast, ovarian or other cancers. Genetic testing for mutations in these two genes has recently become commercially available. There have been varying amounts of psychological distress noted among women with a family history of breast cancer. Distress has been observed to impact psychological functioning, activities of daily living, and the practice of breast cancer surveillance behaviors. Within the genetic screening process, psychological distress has been shown to impact the decision to undergo genetic screening, the comprehension and retention of risk assessment information, as well as affecting the subject following the receipt of the genetic test results. Little work has been done to examine predictors of distress within at risk subjects. This study examines psychological distress among 52 community women presenting for BRCA1 and BRCA2 genetic mutation testing. Predictors of distress included family cancer history, education, age, Ashkenazi ethnicity, and Internality and Powerful Others Health Locus of Control. Vulnerable sub-groups of patients include younger women, women with higher levels of education and women of Ashkenazi ethnicity.

Reactions of psychotherapists in training to religious questions

Reactions of psychotherapists in training to religious questions

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Hutchinson, Geoffrey
Description: This project investigated the spiritual well-being (SWB) of psychotherapists in training and their physiological reactions to religious questions posed by a mock client. Electrodermal activity served as an index of physiological arousal interpreted as anxiety. Thirteen psychotherapists in training at the University of North Texas were recruited. They participated in a simulated intake session with a mock client who asked the psychotherapist neutral questions, personal-other questions (POQs), and personal-religious questions (PRQs). It was discovered that the level of SWB did not affect subjects' anxiety responses to PRQs. There also was no difference in subjects' anxiety responses for POQs between high and low SWB therapists. However, psychotherapists did experience some anxiety associated with questions related to their counseling experience and expertise.

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

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.
Date: May 2006
Creator: Hill, Mary Kathleen
Description: 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.

Sex and Gender Differences in Perceived and Actual Leadership Performance: Self- and Subordinate Views

Sex and Gender Differences in Perceived and Actual Leadership Performance: Self- and Subordinate Views

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Rivero, Arlene Jean
Description: The purpose of this study was to examine how male and female leaders view their own effectiveness as compared to their objective performance. This study also examined sex and gender differences in subordinate's views of male and female leaders. Forty-two mixed-sex groups led by appointed male and female leaders were observed to assess objective and perceived leader effectiveness. Gender role of participants was assessed using the Bem Sex Role Inventory (BSRI). No sex or gender differences were found in objective leadership effectiveness. An unexpected finding was that male and female leaders perceived themselves accurately as leaders. Significant differences were found in the way male subordinates rated men and women leaders when taking into account gender role. Results indicated that the study of gender bias in leadership is complex and should be examined in conjunction with gender role. Social role theory helps to explain this bias.

Simulating Statistical Power Curves with the Bootstrap and Robust Estimation

Simulating Statistical Power Curves with the Bootstrap and Robust Estimation

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Herrington, Richard S.
Description: Power and effect size analysis are important methods in the psychological sciences. It is well known that classical statistical tests are not robust with respect to power and type II error. However, relatively little attention has been paid in the psychological literature to the effect that non-normality and outliers have on the power of a given statistical test (Wilcox, 1998). Robust measures of location exist that provide much more powerful tests of statistical hypotheses, but their usefulness in power estimation for sample size selection, with real data, is largely unknown. Furthermore, practical approaches to power planning (Cohen, 1988) usually focus on normal theory settings and in general do not make available nonparametric approaches to power and effect size estimation. Beran (1986) proved that it is possible to nonparametrically estimate power for a given statistical test using bootstrap methods (Efron, 1993). However, this method is not widely known or utilized in data analysis settings. This research study examined the practical importance of combining robust measures of location with nonparametric power analysis. Simulation and analysis of real world data sets are used. The present study found that: 1) bootstrap confidence intervals using Mestimators gave shorter confidence intervals than the normal theory counterpart ...
