Does What Doesn’T Kill You Make You Stronger? Examining The Effects Of Resilience And Functional Outcomes On Post-Traumatic Growth In Adults With Acquired Disability, Dominique Renee Ghirardi M.S.

Theses and Dissertations

Disabilities acquired in adulthood are often unexpected and disruptive because a loss of functioning can affect one’s ability to maintain employment, pursue their interests, and participate in social activity without assistance or accommodation. This is especially true for those who experience a life-altering injury or develop a chronic health condition between the ages of 18 and 64, as they likely have not planned for the financial and social adjustments that life with a disability involves. However, factors such as post-traumatic growth can reveal the extent to which someone experiences personal growth and improvement in the wake of a traumatic and …

Investigating The Longitudinal Relationship Between Social Motivation And Depression In Autistic Adults, Robyn H. Himelstein

Theses and Dissertations

Autism affects individuals across the lifespan, yet there tends to be limited research and services for autistic adults. This is especially concerning given that autistic adults have high mental health needs, with depression being one of the most common and clinically significant co-occurring conditions. We explored the longitudinal relationships between social motivation, social access (i.e., having opportunities for meaningful social interactions), loneliness, and depression in N=303 autistic adults ages 18-65. Participants completed online surveys about social behavior and wellbeing three times over 3–4 months. We hypothesized that an interaction between higher social motivation and lower social access at Time 1 …

The Emergence And Predictive Utility Of Early Markers Of Social Anxiety In Young Children With Fragile X Syndrome, Conner James Black

Theses and Dissertations

Fragile X syndrome (FXS) is a monogenic neurodevelopmental disorder characterized by elevated rates of intellectual disability, autism, and anxiety. Social anxiety affects approximately 60 percent of individuals with FXS and is cited as one of the most impairing comorbid disorders in FXS; however, little is understood about the developmental patterns of social anxiety markers in young children with FXS. The current study investigates cardiac and behavioral markers of social anxiety across the first five years of life and tests the predictive utility of these variables on social anxiety symptomatology. Participants included 80 children with FXS and 50 neurotypical controls. Participants …

Contingency Management For Opioid Use Disorder: Early Treatment Adherence And Mood, Shelby Renee Goodwin

Theses and Dissertations

Opioid use results in potentially devastating consequences, but medications for opioid use disorder, such as buprenorphine, serve as effective ways to curb cravings and withdrawal, helping an individual reduce their use. Unfortunately, around half of patients discontinue buprenorphine treatment within 30 days and co-occurring conditions such as mood symptoms may serve as additional barriers and decrease engagement. This study sought to examine contingency management (CM; incentives for meeting behavioral goals) as a potential intervention to increase early treatment engagement, as well as the role of total depression, anxiety, and stress (mood) severity in the efficacy of contingency management. New patients …

Evaluating The Acute Effect Of Vaping On Food Intake, Gabrielle Maldonado

Theses and Dissertations

Background: Weight control is a common motive for continued cigarette smoking, and weight concerns pose a barrier to quitting. These effects are driven in part by nicotine’s ability to reduce overall appetite and ultimately body weight. Electronic nicotine delivery systems (ENDS) have been marketed and used for weight control, suggesting that the use of these products potentially may share similar effects as well as barriers to quitting as observed for cigarette smoking. However, little to no controlled clinical lab evidence exists supporting ENDS use for weight control. The present study tested the influence of an ENDS on acute eating behavior …

Analysis Of Referrals To Trauma Psychology And Subsequent Development And Proof-Of-Concept Study Of Provider Mental Health Training At A Level I Trauma Center, Samantha Mladen

Theses and Dissertations

Introduction: Millions of people are traumatically injured each year, with a significant portion going on to develop negative mental health sequelae. Many Level I trauma centers are integrating psychologists to provide acute assessment and intervention to patients at risk for poor outcomes. However, medical providers receive very limited training in how to best refer patients to mental health services and may benefit from such education.

Objective: To characterize current patterns of referral to trauma psychology at a Level I trauma center and to develop, refine, and test proof-of-concept for a new training for referring providers.

Method: One year of patient …

Family-Based Support As Social Determinants Of Health Protective Factor On Depression Of Parents Of Children With Autism Spectrum Disorder, Bisola E. Duyile

Theses and Dissertations

All parents experience challenges in their caregiving roles (Barańczuk & Pisula, 2020). However, parents raising a child/children with disabilities experience different social barriers (Oliver, 1996) that may also contribute to additional stressors in their caregiving role (Tomeny, 2016). Although these parents, on average, have reported greater symptoms of depression than parents of typically developing children, research shows that parents who reported receiving social support had lower symptoms of depression and stress (Das et al., 2017; Singh et al., 2017). Through the social determinants of health (SDOH) framework (ODPHP, 2022), the present study investigated informal/family-based support and its protective impact on …

Exploration Of Dimensional Structure Of Major Psychiatric Disorders Reveals Relationship With Substance Use And Personality, Noah Berley

Theses and Dissertations

Objective: Using a mixture of statistical techniques like structural equation modeling, confirmatory, and exploratory factor analyses, we aimed to determine the genetic factor structure among Externalizing, Internalizing, and Psychotic spectrum disorders through methods that evaluate GWAS-based correlations. Additionally, a subsequent factor analysis based on the most suitable psychiatric model was conducted to understand how non-clinical behavioral traits align with this factor structure.

Methods: Publicly available GWAS summary statistics for twelve major psychiatric disorders, six substance use measures and two personality domains were incorporated into structural equation models. Using the GenomicSEM software package, GWAS-based correlations were estimated between all twelve disorders …
