Evidence-Based Practices And Self-Efficacy: A Quantitative Study Of Mental Health Counselors Treating Clients With Substance Use Disorder, Carl Bastien
Dissertations
Substance use disorder affects a substantial number of individuals in the United States. The specific problem of this research is that it was not known to what extent their use of evidence-based practices is driven by their sense of self-efficacy. The purpose of this quantitative correlational research was to examine to what extent the use of evidence-based practices covary with a sense of self-efficacy for mental health counselors treating individuals diagnosed with a substance use disorder. The study population was 121 mental health counselors who specialized in substance use disorder treatment who completed a digital survey. The study findings did …
Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance
Gottman Processes And Couple Outcomes While Navigating Infertility, Clayton Brigance
Dissertations
Infertility remains one of the most difficult relational contexts for couples. However, some research suggests that some couples actually increase their overall satisfaction in their relationship through infertility due to a deeply shared emotional experience. To the knowledge of the author of this dissertation, no studies exist which explain how couples arrive at their relational outcomes through the experience of infertility. These studies within this dissertation add to the present literature by explaining how couples may arrive at their relational outcome through the lens of Gottman Method Couple Therapy (GMCT). For both studies presented here, 902 participants were recruited through …
Evaluating Outcome Factors Of Childhood Emotional Neglect: An Exploratory Factor Analysis, Taylor Levitt
Evaluating Outcome Factors Of Childhood Emotional Neglect: An Exploratory Factor Analysis, Taylor Levitt
Dissertations
Experiencing childhood maltreatment has been shown to have major implications on adult outcomes. Less is known about the outcomes of childhood emotional neglect (CEN). The purpose of this study was to identify factors related to psychological outcomes of CEN within the domains of depression, anxiety, and alexithymia as a precursor to the development of an inventory. One hundred and fifty participant responses on the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Toronto Alexithymia Scale-20 (TAS-20) were collected. Exploratory factor analysis was conducted where nine factors yielded significant results and were titled, “Depressive Symptoms,” “Difficulty Identifying Feelings,” “Usefulness of …
Development Of An Explainability Scale To Evaluate Explainable Artificial Intelligence (Xai) Methods, Stephen Mccarthy
Development Of An Explainability Scale To Evaluate Explainable Artificial Intelligence (Xai) Methods, Stephen Mccarthy
Dissertations
Explainable Artificial Intelligence (XAI) is an area of research that develops methods and techniques to make the results of artificial intelligence understood by humans. In recent years, there has been an increased demand for XAI methods to be developed due to model architectures getting more complicated and government regulations requiring transparency in machine learning models. With this increased demand has come an increased need for instruments to evaluate XAI methods. However, there are few, if none, valid and reliable instruments that take into account human opinion and cover all aspects of explainability. Therefore, this study developed an objective, human-centred questionnaire …
Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna
Can Ratings Of Item Location Enhance Statistical Item Parameter Estimation? Extending The Feasibility Of Unfolding Irt Models, Michael Mckenna
Dissertations
Research and development of modern psychometric methods such as item response theory have drastically changed the way we understand and carry out the measurement of psychological constructs. Despite this, there has been relatively little adoption by psychological researchers to incorporate these methods into their research. While multiple explanations are surely valid, one oft stated reason is the large sample size requirements of these methods. The sample size requirements of item response theory are needed so that effective estimation of item parameters can be carried out. In an attempt to make these modern measurement methods more accessible and feasible to psychological …
Supervisor-Subordinate Conflict Negotiation: Examining The Core Concerns In Light Of Communication Accommodation And Gender Roles, Piyawan Charoensap-Kelly
Supervisor-Subordinate Conflict Negotiation: Examining The Core Concerns In Light Of Communication Accommodation And Gender Roles, Piyawan Charoensap-Kelly
Dissertations
This quasi-experimental study examined a supervisor-subordinate negotiation of an emotion-laden conflict from the lens of the core concerns framework, communication accommodation theory, and gender roles research. Results empirically support CCF that, by accommodating or attending to the employees’ core concerns, managers can stimulate employees’ positive emotion and integrative intention. However, under- and overaccommodating the core concerns can lead to distributive intention. Additionally, the employees’ perception of manager goodwill can strengthen or attenuate the positive effect of core concerns accommodativeness on outcome variables especially for male managers. Thus, moderate accommodation is recommended for male managers. For female managers, the results show …
Color-Blind Racial Ideology, Social Justice Attitudes, And Cultural Competency In U.S. Medical Students And Resident Physicians, Jennifer G. Hahm
Color-Blind Racial Ideology, Social Justice Attitudes, And Cultural Competency In U.S. Medical Students And Resident Physicians, Jennifer G. Hahm
Dissertations
Health disparities disproportionately affect the lives of racial and ethnic minorities in the United States (Agency for Healthcare Research and Quality, 2015; U.S. Department of Health and Human Services NHQR, 2013). Social conditions, social determinants, and structural inequities have been acknowledged as influential forces on minority health (Link & Phelan, 1995; World Health Organization, 2011). Focusing on eliminating environmental and social conditions affecting the health status of racial and ethnic minorities should be a prerogative for healthcare professionals in reducing health disparities. The purpose of this study is to examine the relationship between color-blind racial ideology and social justice attitudes …
Systems Of Quantity Judgment In Various Species: A Meta-Analysis, Tiffany A. Woodard Baker
Systems Of Quantity Judgment In Various Species: A Meta-Analysis, Tiffany A. Woodard Baker
Dissertations
An abundance of behavioral and neuroimaging literature supports the presence of two cognitive systems for quantity judgments (Agrillo & Bisazza, 2014). In particular, small quantities are thought to be guided by the object-file system, a precise system that uses mental files to map onto real world objects, and large quantities by the approximate number system, an imprecise, estimation system (Dehaene, 1997). Evidence supporting both systems exists in a variety of species including nonhuman primates (Boysen & Hallberg, 2000), birds (Garland, Low, & Burns, 2012), amphibians (Uller, Jaeger, Guidry, & Martin, 2003), and fish (Agrillo, Dadda, Serena, Bisazza, 2009), but support …
Comparisons Of Artifact Correction Procedures For Meta-Analysis: An Empirical Examination On Correcting Reliabilities, Lei Zhao
Dissertations
This study reviewed some challenges and issues in artifact correction meta-analysis, particularly around using reliability estimates to correct for measurement error. Two individual correction procedures—the Hunter-Schmidt procedure and the procedure developed by Raju, Burke, Normand, and Langlois (the RBNL procedure)—are addressed in this research. The purpose of this study is to use real-world data to examine the differences between meta-analytic estimations produced by the two artifact correction procedures and those by the traditional bare-bones meta-analysis procedures, under the condition of inter-dependent reliabilities. The impact of this inter-correlation on meta-analysis results needs investigation when artifact indicators, such as reliability of predictor …
Using Robust Standard Errors To Combine Multiple Regression Estimates With Meta-Analysis, Ryan T. Williams
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 …
Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos
Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos
Dissertations
Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss and cognitive decline. Although the symptomology of Alzheimer’s disease is well defined, its precise etiology remains elusive. Animal models are invaluable for understanding the pathogenesis of this devastating disease. Knowledge of the neurochemical actions of amyloid-β oligomers in specific brain structures is essential for validating animal models of Alzheimer’s disease and for determining the most appropriate behavioral assays of memory. The specific aim of this project was to investigate the neurochemical effects of direct intracerebral infusion of amyloid-β oligomers in the rat. Experiment 1 investigated direct infusions of synthetic …

One hundred African-American women between the ages o f 18 years and 80 years who were born in the United States and for whom English was their primary language were exposed to video taped incidents o f historically accurate racist events from American history. Measures of emotional reactivity including heart rate, blood pressure and measures o f anger and anxiety were taken and the Hollingshead Four Factor Index o f Social Status was used to classify subjects into three socioeconomic levels. The experimental protocol required that subjects be exposed to a period of adaptation followed by a period of exposure …
Correlates Of Life Satisfaction After Retirement, Richard A. Tackett
Correlates Of Life Satisfaction After Retirement, Richard A. Tackett
Dissertations
Much of the literature on aging, retirement, and stages of life has focused on men. The changing role from productive members of society to that of being retired can be either viewed as an opportunity to experience new adventures or depressing for those who are unable to move successfully into the next developmental stage of life. This study examined factors that could contribute to life satisfaction in 144 individuals who were over 65 years of age. The factors that were included in this examination are self-esteem, morale, depression, and demographic characteristics (e.g., age, gender, ethnicity, educational level, marital status, income, …
