Socio-Demographic Risks Affect Executive Functioning, Brittny Rodgers, Nicole Shelley, Hannah B. White, Ph.D

Undergraduate Research Symposium

The goal of study 1 was to see if there was an association between average fixation durations in infants and socio-demographic risk. There were 102 infants (3.5 month old) that participated in the study. While infants were looking at stimuli, the researchers tracked their average fixation durations; their mothers took the socio-demographic risk scale (Rutter, 1979; Sameroff, 2000). This scale shows the mothers cumulative risk score by giving points to mothers based on their socio-demographic circumstances. Mothers received a point if they were, below median maternal education, below median estimated family income, or a racial minority. Results showed that the …

The Association Between Coping-Motivated Drinking And Alcohol-Related Consequences., Jacob D. Salser, Ian A. Mcnamara, Ryan W. Carpenter

Undergraduate Research Symposium

ABSTRACT. Background: College students’ alcohol use is an important topic of research. Past research indicates that people who drink to cope are at a higher risk for alcohol-related consequences compared to other drinking motives (i.e., enhancement, social, or conformity motives). This project aims to analyze drinking motives, specifically the subscales of coping-anxiety motives and coping-depressive motives, and their association with alcohol-related consequences in a unique population. In addition, the moderating effects of stress will be tested.

Methods: The data for this project was collected through a survey that was given to students (N=176) at the University of Missouri …

Hope For The Unhoused: Medical Treatment Access And Retention Among Unhoused Individuals With Opioid Use Disorder In The St. Louis Region, Allison Token

Undergraduate Research Symposium

Medical treatment for Opioid Use Disorder (MOUD) can be highly effective, but may be particularly difficult to access among individuals who are unhoused. This study investigated how experiencing insecure housing affects the receipt of and retention rates of MOUD among participants in the St. Louis region’s Engaging Patients in Care Coordination (EPICC)—a peer-based program designed to connect people with evidence-based OUD treatment. We hypothesized EPICC clients who were unhoused received MOUD less often than clients who were housed, and that EPICC clients who were unhoused were retained in treatment for shorter periods of time than EPICC clients who were housed. …

Telehealth Treatment For Opioid Use Disorder In Missouri’S Urban And Rural Areas Prior To And Since Covid-19, Aurora Rojo, Rashmi Ghonasgi, Zachary Budesa, Rachel Winograd

Undergraduate Research Symposium

Opioid use disorder (OUD) is a chronic health condition that can be adequately treated when individuals have access to needed services. Telehealth services can be delivered remotely through audio-visual technological communications rather than in-person visits, which can greatly improve care accessibility. Following the onset of COVID-19, there were swift clinical and policy adaptations to promote telehealth services across medical and behavioral health fields. This study aims to identify changes in the frequency of telehealth for OUD treatment in Missouri’s rural and urban counties prior to and since the onset of COVID-19. Chi-square tests and analysis of changes between years and …

Effects Of Foster Children’S Epigenetics In Abusive Environments, Shamika Ellis, Theresa Moore

Abstract: Effects of Foster Children’s Epigenetics in Abusive Environments

Shamika Ellis, Theresa A. Moore, Hannah B. White, PhD

This presentation will review the literature on the epigenetics of abused foster children, and the subsequent acute, delayed, and long-term physiological, cognitive, and behavioral effects. One study experimentally investigated the effects of sexual and physical abuse on 150 foster children from 8 to 19 years of age and found post-traumatic stress disorder (PTSD) was diagnosed in 64% of children who experienced sexual abuse and 42% of children who experienced physical abuse Further, of the foster children who had not experienced either form …

Psychopathy & Perceptions Of Control, Amy Kenny

Undergraduate Research Symposium

Psychopathy is a complex personality disorder characterized by egocentricity, antisocial tendencies, and emotionally insensitive behavior. One trait of psychopathy is a grandiose sense of self-worth, related to positive self-regard and egocentricity. A few studies have shown relationships between psychopathy traits and self-report measures of locus of control. However, less is known about how psychopathy traits, including grandiose self-worth, relate to perceptions of control in the moment using computer-based tasks. This study explored the correlation between psychopathy traits and perceptions of control in undergraduate students. We hypothesized that: (1) overall psychopathy scores would negatively correlate with perceptions of control, and (2) …

The Effect Of Caffeine On Bee Behavior: A Progressive Ratio Study, Kayle Cohen, Becky Hansis-O'Neill, Aimee Dunlap Dr

Undergraduate Research Symposium

This presentation focuses on the effect of caffeine on bee behavior using behavioral pharmacology methodologies. Researchers trained bumblebees to drink out of artificial flowers, then administered sucrose nectar or caffeinated sucrose nectar during a schedule of progressive and fixed ratios. The finding suggests that caffeine did increase the number of rewards during the fixed ratio, but not in the progressive ratio. However, research is still ongoing as bees continue to be tested..

The Fentanyl Crisis In The African American Community: Exploring Geographic Differences In Overdose In The St. Louis Region, Tanys Giles, Devin Banks, Rashmi Ghonasgi, Maria Paschke, Rachel Winograd

Undergraduate Research Symposium

The opioid overdose crisis in the United States has disproportionately affected the African American community. These increases are due in part to increased availability of fentanyl in the drug supply. However, little is known about the geographical characteristics of opioid overdose in the post fentanyl era and how it may vary based on neighborhood racial make-up. The current exploratory study investigates the geographic characteristics of opioid overdose in St. Louis City and County from 2016-2021. Data included geographical location of fatal opioid overdose among St. Louis residents (N=3,755). Analyses included examining hotspots (i.e., significantly high clustering) and cold spots (i.e., …

Exploring Best Practices In Umsl’S Collaborative Laboratory Internship And Mentoring Blueprint (Climb) Program, Dakota Warren

Undergraduate Research Symposium

The Collaborative Laboratory Internships and Mentoring Blueprint (CLIMB) was inspired by the University of Missouri–St. Louis and the Jennings School District’s desire to address the opportunity gap among minority students in the St. Louis region. Since its inception in 2015, CLIMB has expanded to meet the needs of local students to reduce the opportunity gap facing disadvantaged local school districts.

U.S. Military Veterans Transition To Two Midwest Universities: Post-Traumatic Stress Disorder, Moral Injury, And Academic Outcomes, Malychanh T. Bartlett

Dissertations

Abstract

Objective: To examine the association between posttraumatic stress disorder (PTSD) and moral injury (MI) and the extrinsic factors of the degree of negative patterns of healthy behaviors and negative experiences in an academic setting, the moderating effects of social support on PTSD and MI symptomatology, and the perception of academic success and positive perception of academic experience. Additionally, to examine the mediating effect of intrinsic factors (perceived academic experience) on academic outcomes objectively and subjectively.

Background: Student veterans as non-traditional students face challenges transitioning to the academic environment. Some have underlying mental and psychological complications of PTSD and MI, …

With A Little Help At Home: The Impact Of Romantic Partner Support On Daily Burnout And Workplace Incivility, Matthew Aplin-Houtz

Dissertations

With rude and discourteous encounters in the workplace becoming more common, Workplace incivility (WI) is at an all-time high. As such, workers experience levels of burnout from these negative social interactions. The literature concedes that the results of these interactions lead to mounting burnout, causing negative physical and emotional outcomes at the individual and organizational levels. Considering that the literature also supports that employees have the potential to recover from burnout symptoms through rest, obtaining the perception of control of their circumstances, and cognitive reframing, the time and activities a worker spends at home carry the potential for minimizing burnout …

Gender And Sociodemographic Discrepancies In Adhd Symptom Endorsement, Tabish Gul

Theses

Historically, the prevalence of attention deficit hyperactivity disorder (ADHD) has been found to be higher in men than women. However, recent work suggests that part of this discrepancy might be because ADHD may manifest in women in less disruptive ways and therefore be underdiagnosed. This issue is compounded by the fact that some ADHD traits may seem more “normative” at certain ages. To further understand potential biases in parent perception of ADHD symptoms, this study examines parent endorsement of the 18 DSM-5 criteria for ADHD cross-sectionally in a non-clinical sample of children from 3.3 to 6 years of age. It …

Treatment Outcome From Cognitive Processing Therapy Examined Three Ways, Sophie Haven

Dissertations

Cognitive Processing Therapy (CPT), a Cognitive Behavioral Therapy for treating Post Traumatic Stress Disorder (PTSD), is an evidence-based treatment that has been demonstrated to be effective in treating PTSD. Nonetheless, CPT can have a high rate of treatment non-completion. Attrition from therapy has been operationally defined using multiple contrasting methods. Understanding attrition using a definition with the most clinical utility is essential to improving outcomes from efficacious treatments. Two clinically relevant definitions for attrition, session attendance and symptom improvement, are critical to understanding attrition. Combining information from both definitions, to create four separate groups, will provide more accurate information about …

Do Allyship And Motivation Influence Women’S Cognitive Functioning And Self-Regulation After Witnessing Sexism?, Christina Garasky

Dissertations

Prior research shows the effects of sexism can accumulate over time, resulting in severe negative, cognitive, affective, motivational, and physiological consequences for women; however, most research focuses on the consequences of being a direct target of sexism, and the cognitive and motivational consequences of being a witness of sexism have not yet been fully explored. Additionally, while it is thought that allyship can help mitigate the consequences of sexism, minimal research has tested this relationship. It was proposed that shifts in reactive approach motivation (RAM); aimed to protect against anxiety and negative affect, may direct attention away from goal-oriented behaviors, …

Self-Compassion And Experiential Avoidance: Potential Pathways To Posttraumatic Growth, Julia Sager

Dissertations

Social support has been identified as one of the most consistent predictors of posttraumatic growth (PTG). Although the role of social support in the process of PTG is informative, social support is intrinsically reliant on other people. Identifying internal, potentially malleable, factors that are associated with PTG is essential for developing preventative interventions to improve trauma-related outcomes and increase levels of PTG among trauma survivors. Internal processes such as self-compassion and experiential avoidance may promote, or interfere with, deliberate processing and the subsequent development of PTG; however, this has not yet been examined in the literature. Thus, the primary aims …

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 …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Correlates Of Psychological Well-Being In Older Adults With Treatment-Resistant Depression, Selmi Kallmi

Dissertations

The purpose of this study was to examine the factors that are associated with psychological well-being in older adults with late-life depression and determine if social participation moderates and/or mediates these relationships. This dissertation study utilized secondary pre-treatment data collected from the “Optimum: Optimizing Depression Treatment in Older Adults” study (Cristancho et al. (2019). Community dwelling older adults (N = 369) were included if they currently met criteria for MDD, had failed at least two prior trials of MDD medication treatment, and were able to visit the study site to participate in cognitive and physical functioning assessments. Hierarchical multiple regressions …

Selfies And The Self: The Influence Of Instagram Posting On Self And Cognition, Giovanni Castillo

Theses

Research on Social Networking Sites (SNS) has shown a variety of both beneficial and detrimental psychological and cognitive outcomes associated with high frequency usage. We conducted an online study consisting of a series of questionnaires and a working memory task to explore the relationship between Instagram use intensity and cognition. The present study first investigated the relationship between Instagram (IG) use intensity, rumination, and cognitive failures. We randomly assigned participants into a selfie-posting, selfie-sending, or likes/comments reporting condition to determine whether selfie-posting behavior affects working memory performance. While we did not find significant associations between IG use intensity, rumination, and …

Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan

Dissertations

Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay …

Externalizing Behavior Predicts Differential Patterns Of Substance Use Among Adolescents By Race, Andrea Palacios

Undergraduate Research Symposium

Externalizing Behavior Predicts Differential Patterns of Substance Use among Adolescents by Race

Early substance use is associated with negative developmental outcomes and chronic disease. Adolescent externalizing behavior (e.g., rule-breaking, lying, aggression) is a consistent predictor of adolescent substance use. However, the association between externalizing behavior and different substances (e.g., alcohol, cannabis, nicotine) is unclear. It is important to clarify these relationships by race as previous research has demonstrated that substance use risk factors for Black youth differ from those for White youth, with whom much research has been conducted.

Non-Hispanic Black (n=16) and White (n = 20) adolescents ages 14-18 …

The Relationships Between Perceived Social Support, Discrimination, Distress, And Alcohol Usage, Kylie Thorwardson, Ryan Carpenter, Melissa Nance

Undergraduate Research Symposium

Those who identify with a sexual minority identity are more likely to experience stress in day to day life due to their identity. Given that alcohol use has been a recorded outlet for stress release, it was hypothesized that the discrimination and distress in those with a sexual minority identity would be positively associated with alcohol consumption. Additionally, it was hypothesized that there would be a negative association between perceived social support and alcohol consumption in individuals who identify as a sexual minority. Regression analysis failed to support all three hypotheses. However, significantly associated correlations were found between: Sexuality and …

Analyzing The Variable Pain, Payton Ruediger, Ryan W. Carpenter, Melissa Nance

Undergraduate Research Symposium

The smartphone apps TigerAware and Qualtrics were used to give participants surveys throughout the course of ten days. The participants were undergraduate students at UMSL who received extra credit for participating in the study. Out of the 126 participants, 13 were male and 113 female. The surveys focused on comparing the relationship between alcohol usage and other variables. These surveys had questions relating to alcohol usage, marijuana usage, mood, pain, and questions about daily functioning. …

Successful Women Majoring In Stem Have Higher Optimism And Lower Stigma Consciousness, Bridget Muise, Bettina Casad

Undergraduate Research Symposium

Women are underrepresented in science, technology, engineering, and math (STEM) education. We had 607 women majoring in STEM complete an online questionnaire reporting levels of coping, rejection sensitivity, stigma consciousness, and optimism and grade point average (GPA) was collected from school records. Results showed that higher rejection sensitivity predicts lower GPA even with higher coping skills. This indicates that even with good coping skills, higher fear of rejection for one's gender had a stronger effect on the academic performance of women in STEM. Additionally, higher optimism predicts higher GPA, but only for women with lower gender stigma consciousness. Optimism seems …

Rethinking Binge Eating Disorder: Is Resource Depletion The Missing Link?, Laura Fewell

Dissertations

Binge eating disorder (BED), the most prevalent of the eating disorders, is associated with significant mental health impairments, high healthcare costs and utilization, and increased mortality. Yet little is known about the mechanisms involved in binge eating, and existing BED theories are incomplete. Scholars have recently suggested that resource depletion, or the state of reduced self-regulation abilities, may apply to BED, but no identified studies have experimentally examined this relationship. The purpose of the current study was to examine the role of resource depletion in binge eating behaviors. Ego anxiety, discomfort anxiety, and dietary restraint were also examined as potential …

Posttraumatic Stress Symptoms, Anger, And Substance Use As Risk Factors For Trauma Revictimization, Hannah E. Walker

Dissertations

Maltreatment survivors are at an increased risk for adult revictimization. Yet, existing work has specifically focused on sexual revictimization, and it is unclear what factors increase one’s risk for revictimization more broadly. Posttraumatic stress symptoms (PTSS), anger, and substance use have been identified as potential risk factors for sexual revictimization. Still, the role of these variables is ambiguous in the broader revictimization framework. There is also a lack of understanding regarding the roles of the DSM-5 posttraumatic stress disorder (PTSD) symptom clusters and revictimization. This study aims to: 1) examine the links between maltreatment and revictimization and three factors (i.e., …

What’S Religion Got To Do With It?: Differing Religiosity Domains’ Association With College Students’ Sexual Consent During First-Time Intercourse, Kaylee Richmond

Dissertations

Within the U.S., 36% of women and 17% of men report experiencing sexual assault (Smith et al., 2017). The absence of sexual consent is often regarded as a defining component of sexual assault (Beres, 2014); thus, a potential area to examine to decrease rates of perpetration and victimization. To date, there has been a lack of research on contextual factors that are likely related to sexual consent, with a general focus on external consent (i.e., verbal/behavioral indicators; Muehlenhard et al., 2016). The present study examined the role of a contextual factor, religiosity, on sexual consent processes during the context of …

Race, Masculinity, And Personality Development: Understanding The Black Male Experience In America, Veronica High

Dissertations

Although men from all racial backgrounds have several poor health outcomes, most of the research suggests that Black men have even worse health outcomes compared to White men (Bowman, 1989; Watkins & Neighbors, 2007; Williams, 2003). The majority of published research on masculinity, however, has primarily focused on samples of White men. The issue of how racism intersects with masculinity and its impact on Black men remains understudied and is a current area of focus in the field. The present study examined relationships between Black men on the cultural measures of masculinity and self-esteem, Dark Triad (narcissism, psychopathy, and Machiavellianism), …
