Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen Dec 2021

Statistical Mediation Analysis In Regression Discontinuity Design For Causal Inference, Donna Chen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Regression discontinuity designs (RDDs) are the most robust quasi-experimental design, but current statistical models are limited to estimates for the simple causal relationship between only two variables: the independent and dependent variables. In practice, intervening variables (or mediators) are often observed as part of the causal chain. Mediators explain the why and how a treatment or intervention works. Therefore, mediation and RDD analysis combined can be a useful tool in identifying key components or processes that make intervention programs effective while making causal inferences for improving student achievement, despite natural constraints, limitations, and ethical considerations. Without an integrated framework of …


Investigating The Fit Of The Generalized Graded Unfolding Model (Ggum) When Calibrated To Irt Generated Data From Dominance And Ideal Point Models, Abdulla Alzarouni Jul 2021

Investigating The Fit Of The Generalized Graded Unfolding Model (Ggum) When Calibrated To Irt Generated Data From Dominance And Ideal Point Models, Abdulla Alzarouni

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The assessment of model fit in latent trait modelling, better known as item response theory (IRT), is an integral part of model testing if one is to make valid inferences about the estimated parameters and their properties based on the selected IRT model. Though important, the assessment of model fit has been less utilized in IRT research than it should. For example, there have been less research investigating fit for polytomous dominance models such the Graded Response Model (GRM), and to a lesser extent ideal point models such as the Generalized Graded Unfolding Models (GGUM), both in its dichotomous and …


Relationship Of Early Life Maltreatment To Self Regulation During An Affective Stroop Task, Sophie Tonjes May 2021

Relationship Of Early Life Maltreatment To Self Regulation During An Affective Stroop Task, Sophie Tonjes

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Background: Previous research has found that childhood maltreatment is associated with emotional regulation difficulties, as well associations with brain structures, such as the amygdala and hippocampus. However, there are individual differences in the effect of maltreatment on emotional regulation, and this relationship may be dependent upon amygdala or hippocampal volume. The present study hypothesized that amygdala or hippocampal volume would moderate the relationship between maltreatment and emotional regulation. Method: Forty-nine college students were assessed for their history of parenting and participated in the magnetic resonance imaging (MRI) study. Moreover, to measure emotional regulation skills, participants completed the Affective Stroop task, …


Attachment Injury-Related Responses From The Offending Partner And Forgiveness In Romantic Relationships, Shruti Pillai May 2021

Attachment Injury-Related Responses From The Offending Partner And Forgiveness In Romantic Relationships, Shruti Pillai

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Attachment injuries in romantic relationships carry the potential for several negative outcomes for the injured partner, the offending partner, and the relationship. Forgiveness can serve to repair the damage caused by such an injury. The concept of forgiveness, however, has predominantly only been studied as the responsibility of and of primary interest to the injured partner. There is a growing need for closer examination of what the offending partner can do to promote forgiveness. The Attachment Injury Resolution Model (AIRM) proposes eight distinct steps including actions for each partner that can lead a couple towards recovery. This study examined the …


Exploring Supervisor Experiences Of Hope In Clinical Supervision: A Phenomenological Approach, Robert Byrom Jr. May 2021

Exploring Supervisor Experiences Of Hope In Clinical Supervision: A Phenomenological Approach, Robert Byrom Jr.

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Supervisory experiences have been identified as one of the primary resources for the clinical training of psychotherapists with respect to both the development of necessary skills and the ability to cope with encountered difficulties. This phenomenological study explored the experiences of clinical supervisors in a current supervisory relationship with one or more supervisees. Specifically, this study explored how supervisors experience their supervisory relationships, how supervisors conceptualize hope as it relates to supervision, how supervisors express hope for their supervisees, and how supervisors promote hope within supervision. Semi-structured interviews were conducted with between 3 to 15 individuals recruited from counseling psychology …


Power, Privilege, And Fraternity Men's Perceptions Of Sex And Sexual Violence: A Phenomenological Study, Justine Diener O'Leary May 2021

Power, Privilege, And Fraternity Men's Perceptions Of Sex And Sexual Violence: A Phenomenological Study, Justine Diener O'Leary

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Sexual violence is a prevalent concern on college campuses (see Washington Post & Kaiser Family Foundation, 2015; Cantor et al., 2015). Men are the primary perpetrators of sexual violence (Black et al., 2011), with particular groups, such as fraternity men, particularly prone to perpetrating sexual violence (Foubert et al., 2007). The CDC (2014, 2021) recommends utilizing a social-ecological model of prevention that address risk factors at four levels: individual, relational, community, and societal. The purpose of the present transcendental phenomenological pilot study was to explore fraternity men’s perceptions of systemic influences on sex, consent, and sexual violence. Utilizing a modified …


Examining The Efficacy Of An Intervention Package Delivered Via An Online Learning Tool To Improve Prerequisite Algebra Skill Fluency, Nicole Bricko Apr 2021

Examining The Efficacy Of An Intervention Package Delivered Via An Online Learning Tool To Improve Prerequisite Algebra Skill Fluency, Nicole Bricko

College of Education and Human Sciences: Dissertations, Theses, and Student Research

This dissertation study investigated the efficacy of a multi-component intervention package delivered via an online learning tool on math fluency for prerequisite algebra skills for three 6th-grade students. Students were referred by their math teacher due to concerns with academic performance. Target skills were individualized for each student based on screening assessments and measured continuously during both baseline and intervention. The multiple-probe across skills design demonstrated that students increased their math fluency on prerequisite skills. A staggered pattern of increases across skills for two participants indicated experimental control was achieved and student’s performance improved. The Quizlet® intervention …
