A Mixed Method Investigation On The Effects Of Information And Motivation On Self-Regulation Skills And Fruit And Vegetable Consumption, Kristen Buford

Theses and Dissertations--Psychology

Introduction: The purpose of this research study is to understand the interplay between health information and health motivation on eating behaviors in African American emerging adults. Greater knowledge of nutrition is linked to healthier eating outcomes, but the motivations that individuals possess about their ability to improve their health also play a pivotal role. However, the joint effect of such constructs (i.e., information and motivation) on eating behaviors is unknown. Emerging adults are still developing their capacities to exercise their health autonomy, and this developmental period represents an opportunity to intervene before the onset of age-related chronic diseases in middle …

A Dual Process Model Perspective On Associations Between Parent And Offspring Problem Drinking, Karallyn E. Fitisone

Theses and Dissertations--Psychology

Parental problem drinking (PPD) is a well-established risk factor for adolescent alcohol use, yet the complex mechanisms involved remain underexplored. The present study addresses this critical gap by examining how PPD, parent emotion socialization, and emerging adult problem drinking are associated within the framework of the Dual Process Model of Substance Use. Participants were 2,036 undergraduates who completed an online survey assessing PPD, retrospective reports of parental reactions to their negative emotions in childhood, and students’ current levels of problem drinking, negative urgency, negative emotional reactivity, and emotion-regulation difficulties. Structural equation modeling was used to clarify the roles of emotion-related …

Multidimensional Health Outcomes In Lgbtq+ Older Adults In The United States: Individual And Community-Level Protective Factors, Emily P. Lapidus

Theses and Dissertations--Psychology

Despite a lifetime of systematic barriers, LGBTQ+ individuals age into late adulthood, likely due to various protective factors. Guided by the Iridescent Life Course Framework (ILCF; Fredriksen-Goldsen & Muraco, 2019), I analyzed unique protective factors at two levels: (1) individual psychological factors (i.e., resilience, identity management) and (2) community-level factors (i.e., LGBTQ+ community connectedness, social support). Health was operationalized as mental health, physical health, and health-promoting behaviors. The present study accounted for covariates (i.e., financial barriers to healthcare, felt subjective age discrepancy, lifetime discrimination). I hypothesized that both stronger individual and community factors would be associated with better physical and …

"We Talk About It At The Dinner Table": Parent Discussions Of Identity And Politics In Diverse Adoptive Families In The United States, Abigail L. Moore

Theses and Dissertations--Psychology

Parents discussing identity and politics with their diverse adolescents can be protective against experiences of political stress and negative outcomes (Anderson, 2023). Identity discrepancies between parents and adolescents may complicate these conversations (McCrimmon et al., 2024). However, this research often only focuses on only one identity (e.g., race or gender; Mendez, 2022). Because negative political climates affect multiple identities simultaneously (Kassing et al., 2021), the current study explores political conversations in diverse, adoptive family contexts with varying (un)shared identities. Through reflexive thematic analysis (Braun & Clarke, 2021), 7 major themes were developed. Results suggest that identity discrepancies may underlie a …

Associations Between Queer Parent Family Socialization And Adolescent Outcomes Among Diverse Lgbtq+ Parent Families In The U.S., Nita U. Kulkarni

Theses and Dissertations--Psychology

Queer parent family socialization refers to the way LGBTQ+ parents talk with their children about what it means to be queer in society, how to handle discrimination, and ways to have pride in their family’s identity. This construct has been linked with positive well-being outcomes in children, and this study used a strengths-based, mixed- methods framework informed by Minority Stress Theory and intersectionality to examine how queer parent family socialization related to several adolescent well-being outcomes, namely internalizing behaviors, social competence, and adaptive coping. Participants recruited across two projects were 191 queer parents with an adolescent and 114 adolescents with …

Living With Flying Colors: Associations Among Lgbtq+ Identity, Religiosity, Spirituality, Community, And Overall Well-Being Among Lgbtq+ Older Adults, Madison T. Diomede

Theses and Dissertations--Psychology

Experiences of discrimination and prejudice place LGBTQ+ individuals in older adulthood (i.e., 55 years old and older) at risk for poor overall well-being. This risk can be especially salient in the Southern and Midwestern U.S., where LGBTQ+ individuals enjoy fewer legal protections than in the Northeast and Western regions of the U.S. In defiance of these odds, LGBTQ+ individuals in older adulthood cultivate overall well-being through psychological-level constructs, like LGBTQ+ identity affirmation, and community-level constructs, LGBTQ+ community connection. Yet, little research has examined these avenues of strength among LGBTQ+ individuals in older adulthood. Guided by Iridescent Life Course Theory and …

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

Interparental Conflict And Sibling Relationship Quality In Emerging Adulthood: An Emotional Security Perspective, Courtlyn A. Fields

Theses and Dissertations--Psychology

Sibling relationships are among the earliest lifelong relationships and have been found to be protective against family dysfunction and positive adjustment outcomes. Yet research on sibling relationships remains limited. The current study aims to expand understanding of sibling relationship quality in emerging adulthood through the application of Emotional Security Theory (EST). EST provides a framework for understanding how adult sibling relationships may be impacted by childhood experiences of destructive interparental conflict. A sample of 1222 undergraduates with siblings completed an online survey. Participants retrospectively reported on interparental conflict and emotional security in childhood, and reported on their current emotion regulation, …

Gender Differences In Preschool Conduct Disorder Symptoms Across One-Year, Madeline K. Petersen

Theses and Dissertations--Psychology

Conduct disorder is a childhood disruptive behavior disorder that exhibits striking gender differences in prevalence, comorbidities, and associated outcomes. These gender differences, particularly symptomology, remain understudied in conduct disorder despite the growing prevalence in females. This paper seeks to examine gender differences in parent rated conduct disorder symptoms in preschoolers overrecruited for disruptive behavior problems at three different timepoints across one-year. It is hypothesized that males will exhibit higher levels of physical aggression symptoms at the initial timepoint with declining rates across a one-year period compared to females, while females will exhibit lower levels of conduct problems at the first …

It Takes A Village: Impact Of Lgbtq+ Community On The Relationship Between Parenting Stress, Parent Mental Health, And Child Adjustment, Kevin Mcaweeney

Theses and Dissertations--Psychology

While LGBTQ+ parented families are largely the same as their cis-het parent counterparts, they still experience unique factors exclusive to them. One such factor is access to the LGBTQ+ community. While research has emphasized the importance of community within the family system, the role the LGBTQ+ community can play for LGBTQ+ parented families is largely unexplored. Additionally, LGBTQ+ research examining parents of adolescents is similarly lacking. Utilizing a sample of LGBTQ+ parents with adolescent children, and informed by ecological systems theory, self-determination theory, and the parenting stress model, I examine the influence parent’s sense of LGBTQ+ community has on the …

The Effect Of Cytomegalovirus Infection On Daily Stress Processes In Early Adulthood, Elana Gloger

Theses and Dissertations--Psychology

Chronic stress increases risk for disease, poor health, and early mortality. Cytomegalovirus (CMV), a common latent herpes virus, may promote neurological changes that increase vulnerability to chronic stress by way of self-regulatory deficits, though this has yet to be directly tested. Investigating CMV at younger ages is crucial to understand the effect of CMV across the lifespan and identify modifiable health-factors for future anti-aging interventions. The present study aimed to investigate how, and for whom, CMV associates with daily stress processes in early adulthood.

Participants (N = 108, M_age = 19.7, 83.3% female, 72% White) completed an in-person lab …

Power Of Perception: The Role Of Perceived Caregiver Mindset Beliefs On Undergraduate Student Academic Engagement, Katherine R. Tanaka

Theses and Dissertations--Psychology

Promoting academic engagement is vital for college student success. Researchers have explored factors like growth mindset, the belief that intelligence can improve with effort, as a driver of academic engagement. Beyond personal mindset, students’ perceptions of key social influences, such as caregivers, also play a role. This study examined how undergraduate students’ own mindsets and perceptions of their caregivers’ mindsets relate to four components of academic engagement: behavioral and emotional engagement, and behavioral and emotional disaffection. Data from undergraduates (N = 1417) were analyzed using surveys, descriptive statistics, hierarchical regression, and exploratory moderation. Students generally reported both a personal …

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 …

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 …

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.

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 …

Sexual Orientation And Gender Expression As Predictors Of Sogie-Based Harassment, Michelle Tam

Theses and Dissertations--Psychology

The current study examined which individuals are most at risk for becoming targets of SOGIE-based harassment (specifically, White, male sexual minorities or White, male gender nonconforming individuals). The study also explored potential motivations behind SOGIE-based harassment (specifically, violations of normality and violations of morality) and whether these motivations are predicted by individual differences (specifically, sexual prejudice, beliefs in heteronormativity, tolerance of ambiguity, and adherence to gender norms). College students (n = 206; 67.5% female) were randomly assigned to one of four conditions, each with a different male target (straight/gender conforming, straight/gender nonconforming, gay/gender conforming, gay/gender nonconforming). Students saw a …

Associations Between Identity And Future Parenthood Among Lgbtq+ Asian/Pacific Islander Americans, Kay Simon

Theses and Dissertations--Psychology

In recent years, the number of lesbian, gay, bisexual, transgender, and queer (and additional identities; LGBTQ+) identified people and the number of Asian Pacific Islander Americans (APIA) have been increasing in the United States (Movement Advancement Project 2019; Newport, 2018). As the individuals in these demographic groups develop over their lifespan, many will become parents and form families, but little work is currently available on the experiences of LGBTQ+ APIA individuals and future parenthood. Here, I report findings on the perceptions and importance of future parenthood, identity development, identity integration, and microaggressions and/or discrimination (as they relate to racial-ethnic and …

Parent School Involvement, Student School Engagement, And Academic Achievement In Children Adopted From Foster Care By Lesbian And Gay Parents, Cassandra P. Vazquez

Theses and Dissertations--Psychology

Sparse research has examined academic outcomes of children adopted from foster care by lesbian and gay (LG) parents. Children who have experienced foster care are at greater risk for negative outcomes, but investment in academic achievement could help buffer potential adversity. Parent and student engagement with school peaks in middle childhood, so this may be an important period for understanding processes that influence academic achievement. This study explores how LG parents (N = 57) of school-aged children (Mage = 10.56 years) adopted from foster care in the U.S. involve themselves in their child’s school, how this involvement may …

The Role Of Attachment And Cognitive Pre-Sleep Arousal On Associations Between Sleep Concordance And Sleep Quality, Taylor L. Elsey

Theses and Dissertations--Psychology

The amount of time someone spends co-sleeping with their partner, known as sleep concordance, has implications for sleep quality in couples. Attachment security has emerged as an important moderator of the association between sleep concordance and subjective sleep quality (Elsey et al., 2019). The current study tested whether cognitive pre-sleep arousal explains this pattern of moderation. Prior research suggests that these associations between sleep concordance, attachment security, and subjective sleep quality may be stronger for women than men, therefore gender differences in associations were also examined. Participants were 204 (68% female) individuals in an exclusive relationship lasting at least 3 …

Examining The Impact Of Social Media Use On Body Dissatisfaction And Eating Disorder Symptomatology Among Adolescents, Ilyssa P. Salomon

Theses and Dissertations--Psychology

Media exposure is often cited as a causal factor in the development of body dissatisfaction, or negative thoughts and feelings toward the body (Grogan, 2017; Thompson, Heinberg, Atlabe, & Tantleff-Dunn, 1999). While eating disorders most commonly emerge during late adolescence (18-21 years), risk factors that predict the later onset of eating disorders emerge much earlier and escalate during adolescence (13-16 years; Hudson, Hiripi, Pope, & Kessler, 2007; Rhode, Stice, & Marti, 2016). Overall, links between exposure to traditional forms of mainstream media (e.g. television and magazines), body dissatisfaction, and eating disorder symptomatology are well- established in the literature, with robust …

Elementary School Children’S Understanding Of Disproportionate Discipline, Sharla D. Biefeld

Theses and Dissertations--Psychology

In the U.S. Black students, particularly Black boys, receive more out of school punishments, are punished more frequently, and are punished for more subjective behaviors than their White peers (Skiba, Michael, Nardo, & Peterson, 2002). This phenomenon is referred to as disproportionate discipline and is an early precursor to the disproportionate number of Black men and boys incarcerated in the U.S. Disproportionate discipline begins as early as preschool, and continues throughout elementary, middle, and high school (Gregory & Fergus, 2017). Perceptions of discrimination greatly impact children’s school involvement, school belonging, and educational outcomes (Brown, 2017, for review). However, little is …

Attentional Control In Infancy: The Role Of Sociodemographic Risk, Cortisol, And The Home Environment, Hannah B. White

Theses and Dissertations--Psychology

Infants’ ability to channel their cognitive resources by controlling their visual attention allows them to be active agents in their learning and development. Individual differences in attentional control have been linked to a wide variety of developmental outcomes including disparities between social classes in cognitive functioning. However, it is yet unknown when in development differences in attentional control related to sociodemographic factors emerge, or how factors of the home environment and the infant’s stress response relate to this effect. Accordingly, Experiment 1 examined whether certain sociodemographic factors, such as socioeconomic and minority status, predict 3.5-month-old infants’ (N = 102) …

Body Processing And Attentional Patterns In Infancy, Rachel Lynn Jubran

Theses and Dissertations--Psychology

Bodies provide important social information, and adults benefit from this information by recognizing and responding appropriately to bodies. Body recognition is enabled by the fact that human bodies are defined by parts, such as the limbs, torso, and head, arranged in a particular configuration. To understand the development of social cognition, it is important to analyze and document how infants come to recognize bodies. Infants are sensitive to distortions to the global configurations of bodies by 3.5 months of age, suggesting an early onset of body knowledge. It was unclear, however, whether such sensitivity indicates knowledge of the location of …

Adopting Identities: Associations Between Adoption, Racial-Ethnic, And Sexual Minority Parent Socialization And Children’S Attachment, Global Self-Worth, And Understanding Of Identity, Kyle A. Simon

Theses and Dissertations--Psychology

Utilizing a sample of lesbian, gay, and heterosexual adoptive parent families with school-age children, results suggested that parents engage in adoption communication less but racial-ethnic socialization more when a child is transracially adopted. No differences were found in lesbian and gay parents socialization practices for adoptive or racial-ethnic identity. Further, lesbian and gay parents engaged in sexual minority parent socialization less than adoptive or racial-ethnic socialization. Children’s self-worth was related to sex but not socialization practices such that girls reported lower self-worth, and no significant associations were present for children’s closeness. Children’s age, sex, and transracial adoptive status were predictive …

The Role Of Couple Sleep Concordance In Subjective Sleep Quality: Attachment As A Moderator Of Associations, Taylor L. Elsey

Theses and Dissertations--Psychology

Sleep is not a solitary activity for the majority of adults, this impacts sleep quality, health, and well-being. Couples experience sleep concordance, or a synchronization of sleep-wake times, which can improve and diminish sleep quality (Gunn et al., 2015). This study explores the association between sleep concordance and sleep quality by examining attachment style as a moderator. Daily sleep diaries were completed by 179 heterosexual couples. Sleep concordance was calculated by dividing total time partners were in bed together by total time at least one partner was in bed each day. Data were analyzed using a multilevel model described by …

Looking The Part: An Examination Of Longitudinal Gender Presentation Among Children With Gay, Lesbian, And Heterosexual Adoptive Parents, Samuel T. Bruun

Theses and Dissertations--Psychology

Gender presentation, appearing in a way that fits social expectations of one’s gender role, represents one of the most obvious ways in which one’s gender identity becomes salient to others. This quality is especially relevant to note given the continued controversy surrounding children’s gender role development when raised by non-heterosexual parents. The current study is an examination of how gender presentation develops in adopted children with lesbian, gay, and heterosexual parents across two time points (Wave 1: N = 106, M_age = 36.07 months; Wave 2: N = 90, M_age = 8.34). Children’s gender presentation was analyzed using …

Gender-Based Harassment In Early Adolescence: Group And Individual Predictors Of Perpetration, Michelle Jennine Tam

Theses and Dissertations--Psychology

The current study examined gender-based harassment in early adolescence and the characteristics of individuals who perpetrate such harassment (specifically, experiences with witnessing gender-based harassment and gender identity). Students in seventh and eighth grade (n = 483; 247 girls, 236 boys) completed surveys containing measures of gender identity (perceived same and other-gender typicality, felt pressure to conform to gender norms, and gender contentedness), and questions about witnessing and perpetrating teasing, bullying, and rejection because of a peer’s gender typicality or atypicality. Results revealed that the more GBH an individual had previously witnessed in their classroom, the more likely they were …

Parental Empathy, Aggressive Parenting And Child Adjustment In A High Risk Sample, Shuang Bi

Theses and Dissertations--Psychology

The current study examined the relation between parental empathy, parenting aggression and child maladjustment in a group of parents who perpetrated child abuse and neglect. Twenty parents who were court mandated to receive a parenting intervention program at the Nest Center for Women, Children, and Families participated in this research study. Information about parental dispositional empathy, parent-child specific empathy, parenting aggression and child internalizing and externalizing symptoms were collected through an interview with the parents. Parents in this study reported high levels of dispositional empathy, but exhibited low to moderate levels of empathy in a parent-child relationship rated by coders. …

The Selfie Generation: Examining The Relationship Between Social Media Use And Early Adolescent Body Image, Ilyssa P. Salomon

Theses and Dissertations--Psychology

Social media use among adolescents continues to increase each year. This study explored how the amount of time spent using social media and the specific behaviors used on social media, namely behaviors that involve self-objectification, were related to early adolescents’ body image (i.e., body shame and body surveillance). Three types of social media popular among adolescents were examined: Twitter, Facebook, and Instagram. The current study also examined whether certain youth are more at risk for negative body image outcomes than others, by assessing whether adolescents who are particularly focused on others for approval (i.e. high self-monitors) show greater decrements in …
