Using Robust Standard Errors To Combine Multiple Regression Estimates With Meta-Analysis, Ryan T. Williams

Dissertations

Combining multiple regression estimates with meta-analysis has continued to be a difficult task. A variety of methods have been proposed and used to combine multiple regression slope estimates with meta-analysis, however, most of these methods have serious methodological and practical limitations. The purpose of this study was to explore the use of robust variance estimation for combining commonly specified multiple regression models and for combining sample-dependent focal slope estimates from diversely specified models. A series of Monte-Carlo simulations were conducted to investigate the performance of a robust variance estimator for each of these approaches. Key meta-analytic parameters were varied throughout …

Social Cognitive Predictors For Undergraduate College Student's Choice Goals In Math And Science: Understanding The Role Of Coping Efficacy, Matthew David Abrams

Dissertations

This study examined the utility of Social Cognitive Career Theory (SCCT; Lent, Brown, & Hackett, 1994) in the prediction of undergraduate college student's math and science interests and choice goals. Coping efficacy and self-efficacy beliefs were assessed separately in order to better understand the relationships between supports, barriers, coping efficacy, and math/science self-efficacy within the SCCT model. Two-hundred and forty-six undergraduate college students completed measures of math and science-related supports, barriers, coping efficacy, self-efficacy, outcome expectations, interests, and choice goals. A model specifying that barriers, but not supports, were directly related to math and science choice goals provided the best …

Towards A Multidimensional Model Of Adaptation For African American Adolescents Exposed To Racial Discrimination, Jamila Cunningham

Dissertations

The purposes of the current study were to 1) examine the associations of racial discrimination to internalizing symptoms, externalizing symptoms and perceived life satisfaction in African American adolescents, and 2) determine Africultural cluster profiles based on indicators of racial socialization, racial identity and culturally relevant coping strategies 3) examine whether cluster profile buffers stress exposed African American adolescents from increased internalizing symptoms, anger and decreased life satisfaction. One hundred-fifty-one African American adolescents (grades 9th - 12th) from four high schools and a community group from a major Midwest city and a major city from the Southeast reported on exposure to …

The Direct And Indirect Impact Of Pain Intensity, Weight Status, And Activity Involvement On Social Competence Outcomes In Children And Adolescents With Spina Bifida, Bonnie S. Essner

Dissertations

The purpose of this study was to test a mediated effects model in which youth with spina bifida who have greater pain, are more overweight, or have worse motor control were expected to have fewer friends and to display worse social performance in part because their higher degree of condition severity interferes with their involvement in developmentally-appropriate activities.

Data for the current study were drawn from the first wave of a larger, longitudinal study of psychosocial adjustment of children and adolescents with spina bifida. The sample was comprised of 108 children and adolescents with spina bifida and shunted hydrocephalus, ages …
