Double Jointed: Gendered Flexibility And The Overextended Self, Grace A. Bromley

Theses and Dissertations

This thesis explores compulsory domesticity and the impulse to overextend oneself, both pressures often associated with the construct of femininity. Through diving into my personal history, which includes growing up in a three-generational home of women, I explore mimesis as it functions in both the replication of identity and in terms of pictorial representation; specifically I address its relationship to gender, manifestation within the body, and the search for subjectivity through the process of making and thinking. In various forms of material explorations, I play with ideas of malleability, mimicry and “embedded” behaviors that are passed down and embodied in …

Associations Among Acculturative Stress, Body Ideal Internalization, Body Dissatisfaction And Disordered Eating Behaviors Among Cisgender Heterosexual And Lgbt People Of Color, Taryn Henning

Theses and Dissertations

Research supports the relation between acculturative stress and disordered eating behaviors (DEBs) across racially and ethnically diverse groups of men and women. However, there is minimal research examining factors that further explain the relation between acculturative stress and DEBs. Also, this relation has not been evaluated in racially and ethnically diverse LGBT individuals. The current study aimed to address these gaps by examining the role of thin-, muscular-, and hourglass-ideal internalization and body dissatisfaction as mediators of the relation between acculturative stress and disordered eating behaviors among cisgender heterosexual Black, Latine, Asian American, Multiracial men and women and LGBT men …

Moonshine Babies, Arghavan Heydareslam

Theses and Dissertations

Moonshine Babies is a two-screen film made of collage/cut-out stop-motion and live-action. It is a visual poem based on my journals from when I recently started living in the US as an outsider. The experience left me feeling divided between the empty present and memories of the past. suggesting that there are collective memories among a group of interconnected individuals that unite them within a single narrative.

There was a moment when I asked, "If you are your memories, what does it mean to be somewhere you have no memories of and no one has memories of you there?"

Memories …

Assessing Providers’ Readiness To Integrate Mat Services In A Primary Care Setting, Carmen Ingram-Thorpe

Theses and Dissertations

Opioid use disorder is a growing concern in the United States. Despite medication-assisted treatment (MAT) being a more effective treatment option than behavioral treatment alone, primary care providers’ rate of adoption and utilization of MAT has not matched the demand of the opioid crisis. The largest barrier facing our local community is the availability of organizations and providers that can and will actually provide MAT services. The purpose of this study was to identify factors that impact primary care providers’ readiness to treat individuals with opioid use disorder (OUD) using MAT. This study used the ADKAR model as framework, which …

Mental Health Help-Seeking Behaviors And Service Utilization Of Black College Students, Troy J. Keys

Theses and Dissertations

Black college students are less likely to seek mental health services compared to other students. While previous research has identified barriers and facilitators contributing to Black college students’ help-seeking behaviors, the current political and social climate and pandemic have negatively impacted their mental health thus warranting the exploration of these factors again. This study aimed to identify the mental health help-seeking behaviors and attitudes of Black college students, the barriers and supports for help-seeking behaviors, their preferred service utilization providers, and their thoughts about promoting mental health help-seeking among their peers. Black college students (n = 21) enrolled at an …

Developing And Testing A Model Of Discrimination, Internalized Oppression, Mental Health, And Suicidality In Disabled Transgender And Gender Non-Binary (Tgnb) Individuals, Stephanie L. Cull

Theses and Dissertations

Transgender and gender nonbinary (TGNB) individuals experience high rates of discrimination and microaggressions that can lead to internalized cisgenderism and adverse mental health outcomes such as depression, anxiety, and suicidality. Individuals with disabilities similarly experience high rates of discrimination and microaggressions that can lead to internalized ableism and increased adverse mental health outcomes. Although both of these populations have been researched separately, very little extant research has explored the intersections of disabled and TGNB identities. The purpose of this study was to explore a hypothesized pathway leading from microaggressions through internalized oppression and mental health to suicidal ideation within a …

From Temporary Nurse Aide To Certified Nurse Aide: Examining Temporary Nurse Aides’ Perceptions Of Situated Learning As Preparation For The National Nurse Aide Assessment Program Examination, Amy Taloma

Theses and Dissertations

The Covid-19 pandemic exacerbated Certified Nurse Aide (CNA) staffing shortages in Long Term Care (LTC) facilities. To address these shortages, the Centers for Medicare and Medicaid Services (CMS) authorized LTC facilities to employ Temporary Nurse Aides (TNA). The American Health Care Association (AHCA) and the National Center for Assisted Living (NCAL) developed free online training for individuals which is much shorter than traditional nurse aide training and does not require hands-on skill training or a clinical practicum. The Federal Public Health Emergency (PHE) ended in October 2022. As a result, TNAs are no longer authorized to work in LTC Facilities …

Considering Systems Of Power And Black And Latine Students’ Belonging In Stem, Korinthia D. Nicolai

Theses and Dissertations

This dissertation focuses on (a) exploring the need for and strategies to facilitate the integration of Critical Race Theory (CRT) and educational psychology and (b) supporting Black and Latine students through examining the impact of systems of power via the integration of belonging and Critical Race Theory. This dissertation follows a three-paper format. In Paper 1, we recognize that psychology researchers can use CRT to explore race and racism. However, psychology scholars may confront growing pains when integrating CRT due to their respective inquiry worldviews–postpositivism and critical–which result in several tensions. These tensions may limit the uptake of CRT in …

Development Of A Validity Scale For The Icd-11 Personality Disorder Measure (Psi-11), Rae Lutz

Theses and Dissertations

Invalid responding is a significant issue in the utilization of self-report information. Invalid responding can be assessed by stand-alone validity measures or embedded validity scales. The International Classification of Diseases (ICD) is one of two major diagnostic systems which provide guidance on diagnosing personality disorder, with the most recent version (ICD-11) providing a fully dimensional model for personality disorders. No existing measures aimed at assessing dimensional personality pathology have addressed the combination of PD severity and trait qualifiers that were based upon ICD-11 guidelines. To address this gap, Clark et al. (2021) developed the ICD-11 Personality Disorder Measure (PSI-11). However, …

I Am Who I Am, Yifei Kong

Theses and Dissertations

I am Who I am

By Yifei Kong, MFA

My thesis research focuses on my cultural background and history as a Chinese woman. I explore the control and restraint of women from ancient times and highlight feminism. Traditional Chinese hair accessories reflect a type of control over women. Unlike traditional Chinese hair accessories, which use a lot of precious metals and precious stones, my work uses recycled aluminum cans. That is an exploration of contemporary jewelry materials and a reflection of women's independent right to choose. With my pieces, women can use their preferred colors without considering their class and …

Neurodevelopmental Trajectories As An Explanatory Mechanism For Adverse Mental Health Outcomes Following Child Maltreatment, Casey Burton Corso

Theses and Dissertations

Affecting one in every seven children in the United States, child maltreatment (CM) is a major public health issue associated with a myriad of adverse outcomes (e.g., alcohol and drug abuse, mental illness, interpersonal violence, sexual risk taking, etc.). While any subtype of CM (e.g., physical abuse, sexual abuse, emotional abuse, and neglect) increases the likelihood of subsequent psychopathology, heterogeneity in psychiatric sequelae of CM is associated with different CM subtypes. Elucidating the underlying mechanisms of this heterogeneity is vital for improving intervention and treatment of CM, and research aimed at accomplishing this is a critical need. One possible explanatory …

Variability In Perceptions Of Complementary Health Approaches Among Graduate Student Trainees, Delaney C. Bilodeau

Theses and Dissertations

Complementary Health Approaches (CHAs) encompass a diverse range of practices which are often used both independently and alongside conventional medical treatments. Understanding how graduate students training in different fields perceive CHAs is important because these professional trainees will go on to occupy roles as healthcare practitioners, researchers, policy makers, and consumers. This study used sequential rank agreement methods (Ekstrøm, Gerds, & Jensen, 2019) to investigate variations in perceptions of CHAs in a sample of graduate students (N = 416) from 140 possible training programs. Ratings of CHA familiarity, perceptions of CHA legitimacy, and willingness to recommend CHAs were compared …

The Influence Of Flavor On The Abuse Liability Of A Heated Tobacco Product And Its Feasibility As A Menthol Cigarette Substitute, Augustus White

Theses and Dissertations

Heated Tobacco Products (HTPs) purport to expose people that use cigarettes to fewer of the harmful or potentially harmful constituents of tobacco while still delivering reinforcing amounts of nicotine (Auer, Concha-Lozano et al., 2017). An exemplar of the HTP class, IQOS, and its three varieties of “HeatSticks” have been authorized by the Food and Drug Administration (FDA) as “Modified Risk Tobacco Products” (MRTP). However, as the FDA is planning to ban menthol as a characterizing flavor in cigarettes, questions remain regarding whether characterizing flavors should be permitted in HTPs (FDA, 2022e). New evidence regarding HTP abuse liability (i.e., the likelihood …

Using Natural Language Processing To Understand The Lived Experiences Of People Identifying With Adhd: What Themes Emerge In Social Media Posts?, Gabby C. Scalzo

Theses and Dissertations

Compared to the amount of research conducted on how to identify and understand children with Attention-Deficit Hyperactivity Disorder (ADHD), there has been relatively little work done to understand the lived experiences of adults with ADHD. Increased understanding of how adults with ADHD conceptualize themselves in the context of their diagnosis would help clinical experts tailor research and treatments to better serve these communities. However, there are several barriers towards conducting high-quality qualitative research, including time- and labor-intensity. This study, informed by qualitative research traditions, used innovative data sources (i.e., social media) and analytic techniques (i.e., machine learning) to reduce these …

Community Informant And Mental Health Provider Perspectives On Access To Mental Healthcare For Lgbtqia+ Communities In Virginia, Chariz Seijo

Theses and Dissertations

The existing literature on mental health disparities for lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA+) populations suggests members of LGBTQIA+ populations are at greater risk of mental health disorders than cisgender and heterosexual individuals. The COVID-19 pandemic has also exacerbated mental health disparities for many, including LGBTQIA+ populations. Combined with mental health provider shortages and anti- LGBTQIA+ bills across the country, inequities in mental healthcare are a significant concern. This qualitative study was designed to gather unique perspectives of key community informants and mental health providers on their experiences with mental healthcare provision to LGBTQIA+ communities in Virginia. …

Relations Between Adverse Childhood Experiences And Substance Use In Adolescents And Emerging Adults: The Moderating Role Of Exposure To Community Violence And Community Support And Community Recognition, Kiara Brown

Theses and Dissertations

Due to historical and current systemic racial inequities, African American adolescents and emerging adults living in low-income urban communities bear the burden of higher rates of adverse childhood experiences (ACEs) and exposure to community violence. Both exposure to ACEs and community violence are linked to higher levels of substance use. However, limited research exists on how exposure to community violence exacerbates the association between ACEs and higher frequencies of substance use in adolescence and emerging adulthood. There is also a need to understand how community-level protective factors may weaken the relations between ACEs and higher rates of substance use. The …

Shinners, Alexis E. Mabry

Theses and Dissertations

Shinners is a project that aims to examine the position of women in subcultures and capture conversations of women in subcultural sports. Within feminism, sociological constructs, campy horror, and personal experience I am manifesting the physical and mental obstacles faced in the subcultural sport of Bicycle Motocross (BMX) through photography, painting, collage, video, and sculpture. I interpret images posted to social media of injuries obtained while riding BMX as forms of empowerment, bodily gore as extreme evidence of participation, performative violence, valorizing the understanding of both the physical and psychological pain of failure, and the use of failure as a …

“I Know What Nothing Means”: Nostalgia, Hope, And The Postmodern Search For The Sublime, Kathryn L. Donati

Theses and Dissertations

Amid simultaneous crises of self, nation, digital citizenship, global health, climate change, and socio-political polarization, to name but a few of the catastrophes that seem to define life in the global West in the twenty-first century, where do we find hope? Do we find it at all? Is there any hope to be found? These are the questions that serve as the genesis for this undertaking in which I locate the origin of these crises far before the events of the 2016 and 2020 elections, far before even the panic of Y2K. I begin my examination of hope in contemporary …

Theses and Dissertations

Tobacco dependence has posed a significant public health challenge in the United States and disproportionately affects Latine adults' risk of developing a variety of adverse health conditions. Childhood trauma is a recognized risk factor for dependence, overall health, and mental health concerns. Still, the influence of compassion for self or compassion for others in this context remains unclear. This cross-sectional study investigated the moderating effects of self-compassion and compassion for others on the relationship between childhood trauma and cigarette dependence among Latine adults. Data was collected through questionnaires assessing childhood trauma, self-compassion, cultural values and factors, compassion for others, and …

Sense Make Before Book, Bradley Sinanan

Theses and Dissertations

“Sense Make Before Book” is an Indo-Caribbean turn of phrase which refers to common sense being more important than book smarts. My sister sent me a post the other day on Instagram of an Trinidadian woman using this phrase, saying it was one of Indo-Caribbean origin. I was interested and asked my mom about it. My mom says that when she was younger my grandpa said it often around their house in Princes Town, Trinidad and Tobago. This adage feels charged thinking about the history of indenture and its effects on the Indo-Caribbean diaspora.

The written word of archival history …

Evaluating The Role Of Interoceptive Awareness In Insomnia And Across The Sleep Health Spectrum, Lara Lobrutto

Theses and Dissertations

Interoceptive awareness, characterized by a non-judgmental and trusting attitude towards body sensations, is an understudied construct that is implicated in sleep and health outcomes. Interoceptive awareness is cultivated via contemplative and mindfulness-based practices. Given that it may be utilized to reduce pre-sleep arousal, which is a key mechanism in insomnia, interoceptive awareness is posited to be a protective factor for sleep health. A cross-sectional study was conducted among undergraduate university students (N = 420) in the Mid-Atlantic region of the United States to assess the association between interoceptive awareness and sleep outcomes. Participants received a survey link and completed …
