Body-Based Harassment And Eating Disorder Symptomology In Cisgender, Transgender, And Gender Nonconforming Individuals, Sharla D. Biefield

Theses and Dissertations--Psychology

Past research estimates that over 60% of adolescents and young adults report eating disorder symptomology (EDS), increasing their risk for psychiatric and physical comorbidities, substance abuse, and self-harm. EDS rates are also higher among transgender and gender nonconforming (TGNC) individuals. TGNC individuals also experience higher rates of bias-based harassment, than their cisgender peers. Much of this harassment is body-based harassment (BBH), such that the harassment often targets aspects of an individual’s body. The current study utilized a pantheoretical framework, incorporating minority stress theory and objectification theory, and a multi-method approach to investigate (1) if BBH increases TGNC individuals’ risk for …

Longitudinal Perspectives On Individual Outcomes, Family Functioning, And Social Support Among Diverse Adoptive Families, Emily Lapidus

Theses and Dissertations--Psychology

Given that family processes change when a child enters adolescence, it is imperative for research to utilize longitudinal analyses to capture a family unit’s development over time. This research is especially lacking amongst diverse families, such as those formed utilizing adoption or headed by same-gender parents. Utilizing both the Parenting Stress Model and Family Systems Theory, it has been shown that family dynamics are key indicators when predicting functioning within a family, opposed to family structure. Therefore, it is hypothesized that there will be no significant differences related to family processes (e.g., family functioning, parenting stress, adolescent adjustment, and social …

Birds Of A Feather: Exploring Social Facilitation Effects On Learning And Suboptimal Choice In Pigeons (Columba Livia), Peyton Mueller

Theses and Dissertations--Psychology

The social facilitation effect describes a change in the behavior of an individual due to the presence of another organism of the same species (i.e., a conspecific). Many theories exist that attempt to explain why this change in behavior exists across species. A set of four experiments were executed to best explain how pigeons learn in the presence of non-competing conspecifics. The first experiment sought to replicate an interesting effect previously found in cockroaches and rats, such that conspecific presence inhibits performance early in training but facilitates it with increased training. The second experiment placed the novel response acquired in …

Victimization, Symptoms Of Posttraumatic Stress Disorder, And Gender As Predictors Of Long-Term Substance Use Outcomes Of Patients In Community Treatment Programs, Christopher John Penn

Theses and Dissertations--Psychology

Violence victimization and posttraumatic stress disorder (PTSD) are prevalent among individuals with substance use disorders (SUDs). Current evidence is mixed regarding the impact they have on substance use-related treatment outcomes and few studies have examined victimization and PTSD symptoms together in the same model. The current study will evaluate whether there is an indirect effect of past year victimization on substance use-related treatment outcomes through the pathway of PTSD symptom severity, among a subsample of 1,613 adult men and women reporting a lifetime history of victimization who participated in the Kentucky Treatment Outcome Study (KTOS), a statewide study evaluating federally- …

Prenatal Ethanol Exposure Impairs Performance On Spatial And Tactile Sequential Discrimination Task In Juvenile Rats, Caleb S. Bailey

Theses and Dissertations--Psychology

Fetal alcohol spectrum disorders (FASDs) are a set of cognitive and behavioral abnormalities that arise in ~5% of children who have been prenatally-exposed to alcohol. Prenatal alcohol exposure (PAE) can cause impairments in learning acquisition, working memory, response inhibition, and attentional-set shifting that result in exaggerated deficits in executive function and impairments in goal-seeking behavior. There are standard procedures used in rodent research to address some components of these deficits, but few procedures are sensitive enough to comprehensively assess such deficits. To address this issue in FASDs research techniques, we developed a procedure that requires prolonged executive function in a …

The Effects Of Escalated Fentanyl Intake On Decision-Making Dynamics, Trinity Shaver

Theses and Dissertations--Psychology

Opioid Use Disorder is characterized partially as a decision-making disorder. Decision-making theories, such as habit theory and relative value theory, have aimed to better understand the shift in preference for drug over other alternatives. In order to compare these two contrasting theories, an allomorphic concurrent choice task will run in tandem with an escalation procedure. Male and female Sprague-Dawley rats were tested for choice differences in an allomorphic choice procedure. Reward dimensions, such as relative reward rate, were manipulated within sessions, and magnitude (remifentanil dose), was manipulated between sessions. To study the effects of escalated fentanyl intake on relative valuation, …

The Role Of Maladaptive Emotion Socialization In Risk For Urgency And Problem Drinking In Adolescents, Emily Atkinson

Theses and Dissertations--Psychology

Negative urgency (NU; the tendency to act rashly when experiencing negative emotions) is a robust risk factor for a number of problem behaviors, including early adolescent drinking. Little is known about the factors that precede the development of NU, and hence the full etiology of this component of risk. The current study aimed to investigate the possibility that childhood maladaptive emotion socialization (MES; the tendency for children’s expressions of emotions to be met with punishment, minimized, or invoke a reaction of distress from their parents/caretakers) increases risk for the development of NU. Secondarily, the study tested whether MES predicts increased …

The Effects Of Social And Nonsocial Contextual Stimuli On The Renewal Of Cocaine Seeking, Bree Humburg

Theses and Dissertations--Psychology

Those with substance use disorders can undergo craving and relapse when re-exposed to a drug-associated context. This study determined if renewal of cocaine seeking is differentially controlled by contexts consisting of social and/or nonsocial stimuli. Experiment 1, rats self-administered cocaine in Context A which included a social peer and house light illumination. Following self-administration, rats were randomly assigned to an AAA or ABA group for extinction and renewal. For the AAA rats, context was similar to self-administration; for ABA rats, the drug-associated stimuli (peer and house light) were removed (Context B). Following extinction, renewal of cocaine seeking was examined by …

Seeing The System Vs Seeing The Individual: How Contextual Information And Framing Facilitate Perceptions Of Structural Inequality, Derek Kahng

Theses and Dissertations--Psychology

The current study investigates factors that facilitate adolescents' structural attributions. Namely, we focus on two main factors. First, we investigate if contextual information such as intergroup/intragroup comparisons and group/individual level framing of inequalities affects the likelihood of making structural attributions to race-based inequalities in academic achievement. Second, we investigate if the likelihood of making structural attributions differs based on individual characteristics, such as the individuals’ race/ethnicity, subjective and objective social status, and belief in meritocracy and a just world. Results and its implications will be discussed in the paper.

The Effects Of Extended Fructose Access On Relative Value And Demand For Fructose, Saccharin, And Ventral Tegmental Stimulation, Megan Halloran

Theses and Dissertations--Psychology

Globally, food addiction (FA) is a growing area of research and is largely attributed to the availability of foods that are both energy dense and high in fats and sugars. Further, it has been suggested, that sugar and fat, when consumed frequently, have properties similar to drugs of abuse. While the validity of FA is questioned, researchers have drawn parallels between substance use disorder (SUD) and FA. For example, sugar binge models emphasize craving, withdrawal and binging as primary components of FA, which are also hallmarks of SUD. Additionally, both natural rewards, like sugars, and drug rewards act on the …

Trait Impulsivity And Acute Alcohol Responses As Markers Of Binge Drinking In Young Adults, Holley Jamison

Theses and Dissertations--Psychology

Impulsivity, tolerance to alcohol-induced motor impairment, and high sensitivity to alcohol-induced disinhibition each have empirical support as markers of alcohol-related problems. However, research on alcohol response and personality-based markers of risk have remained largely independent lines of research. This dissertation examined how individual differences in these well-established markers may interact to additively contribute to heavy drinking.

Participants were 96 young adults (21-33 years old). with no history of AUD. They self-reported their drinking habits over the prior 90 days, and behavioral tasks measuring disinhibition and motor impairment were administered on two separate days following two alcohol doses (active [0.65 g/kg] …

Calcium Imaging Of Central Amygdala Activity After Fentanyl Escalation, Samantha Malone

Theses and Dissertations--Psychology

Evidence suggests that rats given long access (LgA) sessions to self-administer (SA) opioids escalate their intake, while also showing greater withdrawal severity and drug-induced reinstatement compared to rats maintained on short access (ShA) daily SA sessions. Little is known about the neural changes that occur during opioid escalation that may impact withdrawal and relapse. Past work examining opioid SA using ShA sessions in rodents has identified the central amygdala (CeA) as an area of interest that becomes hyperactive in acute withdrawal and may be involved in the incubation of craving that occurs after protracted withdrawal. However, these studies have not …

Bipolarity Of Maladaptive Personality Traits In The Alternative Model Of Personality Disorders, Alexandra Hines

Theses and Dissertations--Psychology

It has been posited that extremely high or extremely low levels of any personality trait in the Five Factor Model of Personality can be maladaptive. However, the Alternative Model of Personality Disorders (AMPD) in Section III of the DSM-5 is composed almost exclusively of unipolar maladaptive traits. The lack of maladaptively low neuroticism and high extraversion fails to fully cover psychopathy; the lack of maladaptively high extraversion fails to cover histrionic personality disorder (HPD); the lack of maladaptively high agreeableness fails to cover dependent personality disorder (DPD); and the lack of maladaptively high conscientiousness fails to cover obsessive-compulsive personality disorder …

Personalized Longitudinal Network Models Of Alcohol Use: A Mechanistic Approach, Stephen Semcho

Theses and Dissertations--Psychology

AUD and high-risk drinking are significant public health concerns, and prevailing diagnostic models fail to account for the within-person variability in AUD presentation and the role of functional mechanisms that maintain drinking outcomes. The ETOH Framework highlights the importance of three primary superdomains that maintain and characterize AUD – reward salience, cognitive dyscontrol, and negative emotionality. The current study was the first attempt to investigate the role of the primary ETOH mechanisms, along with positive and negative affect, on alcohol use outcomes, using a novel approach to model individual-level networks of relations over time. This study gathered twice-daily diary data …

This Is Who I Am: Identity Development And Importance Among Diverse Youth From Lgbtq+ Parent Families, Madison T. Diomede

Theses and Dissertations--Psychology

Although the literature on identity and related constructs among adolescents, emerging adults, and diverse populations is growing, little research has investigated identity among adolescents and emerging adults specifically in the context of LGBTQ+ parent families. The present study seeks to fill this gap in the literature by qualitatively investigating identity development and importance among diverse youth with LGBTQ+ parents. Participants are 51 youth (ages 12-25 years) with at least one LGBTQ+ parent. Trained personnel conducted remote, audio-recorded, semi-structured interviews from December 2018-February 2020. Interviews included questions about participants’ individual identities and conversations they have had with their parents about those …

The Condom Use Outcomes And Sexual Functioning Of Young Adult Latinas: The Roles Of Intimate Partner Violence, Posttraumatic Stress Disorder, And Marianismo Beliefs, Jessica Flores

Theses and Dissertations--Psychology

Intimate partner violence (IPV) has been linked to poorer condom use outcomes and sexual functioning in women broadly. Limited studies have examined these associations in Latina samples through a culturally sensitive, trauma-informed lens. A sample of 383 U.S. Latina/Latinx/Hispanic women (Mage = 25.29 years; SD = 4.44) who had a past-year intimate relationship completed a cross-sectional online survey of IPV history, posttraumatic stress disorder (PTSD) symptoms, marianismo beliefs (i.e., traditional Latina gender role expectations), condom use outcomes (i.e., condom use attitudes, efficacy, negotiation efficacy, and behaviors) and sexual functioning. Linear regression models found that past-year IPV was positively related …
