Social Determinants Of Mental Health Outcomes, Ariana Fein

Honors Theses

Mental health disorders, particularly anxiety and depression, are a growing global concern with profound consequences on individuals' well-being and societal functioning. The burden of these disorders is not only psychological but also economic, affecting quality of life. Mental health outcomes are heavily influenced by a range of social determinants, such as financial status, education, and access to healthcare. While extensive research has focused on WEIRD (Western, Educated, Industrialized, Rich, Democratic) countries, there remains a significant gap in understanding how these determinants affect mental health in low-resource settings or non-WEIRD countries. This study aimed to address this gap by exploring the …

Predictors Of Anxiety And Depression In Dental Students - A Nationwide Study, Margaret Xiaojiao Yang

PCOM Psychology Dissertations

Student mental health is a growing concern in higher education, particularly within rigorous clinical training programs. This study estimated the prevalence of anxiety and depression among U.S. dental students and examined associations with resilience and perceived institutional and faculty support. A cross-sectional survey was administered to more than 1,100 full-time students at over 30 accredited dental schools. The instrument collected demographics, the Brief Resilience Scale (BRS), the Generalized Anxiety Disorder–7 (GAD-7), the Patient Health Questionnaire–9 (PHQ-9), and four items assessing perceived support. Among respondents who completed the GAD-7 (n = 965), 43% scored ≥ 8, indicating probable generalized anxiety disorder. …

Ketamine Infusion Treatment For Depression, Isabella Schwing

Capstone Showcase

Depression remains a significant public health challenge in the U.S., affecting millions of adults and contributing to both psychological and financial burdens. Major depressive disorder impacts approximately 14.5 million U.S. adults, with about 30% of cases classified as treatment-resistant depression. Traditional antidepressant therapies, including selective serotonin reuptake inhibitors and serotonin-norepinephrine reuptake inhibitors, often have delayed onset and limited efficacy, leaving a substantial portion of patients without adequate relief. Given these limitations, there is an urgent need for alternative treatment options.

Recent research has highlighted ketamine as a promising intervention for Major Depressive Disorder and Treatment Resistant Depression. Initially identified as …

Self-Determined Strategies For Physical Activity Motivation Among Women With Polycystic Ovary Syndrome, Pamela J. Wright Phd, Ms, Med, Rn, Cen, Cynthia Corbett Phd, Rn, Faan, Bernardine M. Pinto Phd, Fapa, Fsbm, Fabmr, Michael D. Wirth Msph, Phd, Face, Robin M. Dawson Phd, Rn, Cpnp-Pc

Publications

BACKGROUND: According to clinical practice guidelines for polycystic ovary syndrome, first-line treatment includes performing 150 min of moderate-to-vigorous physical activity on most days of the week plus at least 2 days of resistance training. However, < 40% of women with polycystic ovary syndrome engage in regular physical activity, and about 60% are sedentary. Research evidence supports theory-informed physical activity interventions to improve motivation for physical activity. This study examined the fit of a behavioral change theory for women with polycystic ovary syndrome. OBJECTIVES: The purposes of this qualitative study were to analyze physical activity barriers through the lens of self-determination theory and identify motivational strategies that may promote initiation and maintenance of physical activity among women with polycystic ovary syndrome. DESIGN: The study involved a qualitative, descriptive design using theory-driven thematic analysis. METHODS: After emailing a demographic questionnaire and Personal Health Questionnaire-8 to screen for depressive symptoms, participants (n = 7) met three times via Zoom during the summer of 2021. Meetings were audio-recorded, transcribed, and analyzed. RESULTS: Participants were aged 33.9 (±8.1) years, premenopausal, mostly White (71%), educated (100% with at least some college), employed full-time (86%), and married (86%) with a mean depressive symptoms score of 6.4 (±3.4) indicating mild depression. Strategies such as a buddy system, physician support, technology, and behavioral change techniques are necessary to meet the psychological needs of autonomy, competence, and relatedness among women with polycystic ovary syndrome to help increase exercise motivation. CONCLUSION: Findings supported the use of self-determination theory by emphasizing that the social context of polycystic ovary syndrome can undermine physical activity behavior. Thus, physical activity interventions should consider the social context, peer support system, and mental health status of women with polycystic ovary syndrome, and include tailored programs and motivational strategies to help meet the psychological needs of autonomy, competence, and relatedness.

Comparative Efficacy Of Hallucinogens In Treating Mood Disorders Through A Meta-Analysis Of Symptom Reduction, Dosage, And Duration, John Marco D.F. Muniz

Honors Undergraduate Theses

Background: Hallucinogens including psilocybin, lysergic acid diethylamide (LSD), ketamine, N,N-dimethyltryptamine (DMT) (as ayahuasca), have re-emerged as potential rapid-acting treatments for mood disorders. We conducted a meta-analysis of placebo-controlled trials evaluating their efficacy in depression and anxiety disorders. Methods: A systematic review identified 12 trials (Total ≈ 670) meeting inclusion criteria (randomized, placebo-controlled). Data on Cohen’s d and Hedges’ g effect sizes for depression- and anxiety-related outcomes were extracted. We computed pooled effect sizes (weighted by sample size and inverse variance), performed subgroup analyses by drug, diagnosis, follow-up duration, and outcome measure type, and assessed heterogeneity (I², Q …

Cognitive Impairment And Depression In Hispanic And Non-Hispanic White Low-Income Older Adults A Cross-Sectional Study, Cecil Latta

Honors Undergraduate Theses

Hispanic older adults represent a growing population in the United States and may be disproportionately affected by cognitive impairment and depression. We theorize that cognitive impairment would be more prevalent in the older Hispanic community and would affect the levels of depression in both Hispanic and non-Hispanic Whites older adults. This cross-sectional study examined the association between cognitive impairment and depression in 157 older adults, including Hispanic (n = 91, 57.96%, age: M = 76.4, SD = 6.8) and non-Hispanic White (n = 66, 42.04%, age: M = 76.2, SD = 6.5).

Nurse-Led Cbt For Depression In Heart Transplant Patients: A Feasibility Study, Matthew R. Wallace

DNP Projects

Background: Heart transplant recipients are at an elevated risk of experiencing depressive symptoms compared to the general population. Those with depression post-transplant face increased complications, e.g., infection, organ rejection, prolonged hospitalization, and higher mortality rates. However, specific psychotherapeutic interventions tailored for heart transplant recipients remain limited. Nevertheless, there is substantial evidence supporting the effectiveness of various interventions for adults with heart failure, a condition frequently diagnosed in these patients. This suggests that successful strategies for managing depressive symptoms in heart failure patients could be adapted for heart transplant recipients.

Purpose: The purpose of this project was to evaluate …

Racial-Ethnic Differences In The Associations Between Functional Disabilities And Subsequent Depression Among Community-Dwelling Midlife And Older Adults In The Us, Debasree Das Gupta, Uma Kelekar, Kallol Kumar Bhattacharyya, Sidney Carl Turner

Kinesiology and Health Science Faculty Publications

Background: The intersection of race/ethnicity with disability is a critical dimension of mental health outcomes in later ages that remains under-investigated.

Objective: We examined the role of race-ethnicity in moderating the associations between functional disabilities and subsequent depression among Americans 51 and older and stratified into the two age-groups of midlife (51-64) and older adults (≥65).

Methods: Using a nationally representative sample of community-dwelling Americans (≥51; n=7,475) in the 2016-2018 Health and Retirement Study, we conducted bivariate and multivariable regression analyses. Racial-ethnic groups included non-Hispanic (NH) Black, Hispanic, and NH White and a binary (0/1) outcome defined subsequent depression in …

Effect Of The Lifestyle, Exercise, And Nutrition Weight Loss Intervention On Depressive Symptomatology Among Breast Cancer Survivors, Ziyuan Ma

Public Health Theses

Background: Breast cancer patients have up to a five-fold higher risk of depression compared with the general population, with an estimated prevalence of depressive symptoms of 25%. Depressive symptoms among breast cancer patients can affect treatment adherence, quality of life, and mortality. Some studies indicate lifestyle interventions can lower depression symptoms in general population samples; however, few studies have examined changes in depression among breast cancer survivors enrolled in lifestyle interventions. The purpose of this study was to examine the effect of a 6-month diet-and exercise-induced weight loss intervention versus usual care on depressive symptomatology among breast cancer survivors.Methods: 151 …

Globally, Depression is a serious public health concern among elderly populations. The aim of this study was to estimate the prevalence of depression and its coping strategies among geriatric population and to evaluate the association between socio-demographic factors and level of depression.

Methods: A cross-sectional study was conducted among 410 study participants in both rural and urban areas. Geriatric Depression Scale (GDS-15) was used to measure the depression and brief-COPE (28-items) scale was used to measure the coping …

Investigating The Impact Of A Brief Self-Compassion Intervention On Shame And Psychopathology For Women With Histories Of Childhood Emotional Abuse, Sarah Hill

Graduate Research Theses & Dissertations

Background: Childhood emotional abuse, while frequently co-occurring with other types of abuse, is often neglected within the trauma literature, but has been found to be an important independent predictor of adult psychopathology. Shame represents a potentially important and malleable factor that may contribute to the development and maintenance of poor psychological outcomes. As such, interventions focused on increasing self-compassion have been identified as promising methods to decrease experiences of shame, and ultimately symptoms of psychopathology. While literature on brief self-compassion interventions has rapidly increased in recent years, notable gaps remain. Specifically, there is limited research exploring the impact of brief …

Imagine For Tomorrow, What You Cannot Feel Now – The Role Of Anhedonia In Imagery-Enhanced Behavioral Activation, Max Heise, Julie L. Ji, Jessica Werthmann, Fritz Renner

School of Psychology

Preliminary evidence suggests that mental imagery-based elaboration of rewarding activities enhances anticipated pleasure, motivation, and behavioral engagement in non-clinical samples, but its effects in individuals experiencing anhedonia (loss of pleasure/interest) is unclear. Study 1 (N = 90) contrasted imagery-enhanced activity scheduling with two scheduling-only control conditions (Reminder/No Reminder Control) in an unselected sample. Study 2 (N = 108) compared imagery-enhanced activity scheduling with two control conditions (Neutral Imagery/Motivational Verbal Reasoning) in individuals experiencing mild to moderate anhedonia. Both studies measured changes in activity appraisal (anticipated pleasure, anticipated reward/mastery, motivation) in the lab, and behavioral engagement across a subsequent 7-day period. …

Short-Term Health And Safety Outcomes Associated With Digital Hotline Use At Interpersonal Violence-Focused Agencies, Leila Wood, Elizabeth Baumler, Rachel J Voth Schrag, Aly Kramer Jacobs, Jeff R Temple, Erin Clark

Faculty, Staff and Student Publications

Community organizations strive to help survivors of intimate partner violence (IPV), stalking, sexual assault and human trafficking address health and safety needs. Hotline, offered by local agencies, is the first line of support for survivors to address needs. Increasingly, hotline is offered in digital formats (chat and text) to meet the emergent needs of survivors. Despite the growing use of digital hotline, little is known about short-term health and safety changes associated with use. Partnering with 2 local agencies in a Southern state, we recruited first-time digital hotline participants to an online baseline and follow-up (6 weeks later) assessment (n …

A Multilevel Framework For The Promotion Of Maternal Mental Health And Well-Being During The Perinatal Period, Jenn A. Leiferman, Jessica Walls Wilson, Charlotte V. Farewell, Chelsea Walker-Mao, James F. Paulson

Psychology Faculty Publications

Background: Depression and anxiety are prevalent in the perinatal period and may contribute to adverse maternal and child health outcomes. A focus on multilevel protective factors may be effective in promoting well-being and increasing quality of life (QOL) in the perinatal period while simultaneously reducing or preventing depression and anxiety symptoms. We tested a conceptual model that posits specific personal, social, and community factors affecting depression, anxiety, and QOL among pregnant and postpartum individuals.

Methods: Four hundred and thirty-eight pregnant or postpartum individuals completed a 121-item cross-sectional survey composed of validated tools that assessed multilevel protective factors, health behaviors, and …

Examining The Relationship Between Bicultural Stress And Mental Well-Being Among Second-Generation Filipino Americans Living In The United States, Krista Parker

Antioch University Dissertations & Theses

Research investigating the bicultural and mental health experiences of Filipino Americans, the third largest Asian American group in the United States, are consistently overlooked, with second-generation Filipino Americans (SGFAs) facing greater risk of adverse mental health outcomes. This quantitative study addresses a critical gap in research by examining the relationship between bicultural stress and mental well-being among SGFAs living in the United States. Using a cross-sectional survey design, a multivariate regression analysis examined the relationship between bicultural stress and four mental health constructs (as measured by depression, anxiety, stress, and self-esteem) among 302 SGFA participants. Results from this study strongly …

Subthreshold Depression In The National Epidemiologic Survey On Alcohol And Related Conditions Iii (Nesarc-Iii): A Quantitative Analysis Of Prevalence, Characteristics, And Burden In A Nationally Representative Sample, Scott T. Young

Antioch University Dissertations & Theses

While subthreshold depression (subD) is relatively young for a diagnostic concept at a mere half century old, it has burdened individuals and societies for far longer. Research has established that it is a highly prevalent, clinically important entity with clear links to personal distress and impairment (including increased suicidal ideation and behavior), societal burden (e.g., increased reliance on public assistance programs), and economic costs (both personal and public). Research has also demonstrated that it represents a significant risk factor for incident major depression (MD) and that it likely represents both a prodromal and residual state in the normal course of …

Investigating Protective And Risk Factors And Predictive Insights For Aboriginal Perinatal Mental Health: Explainable Artificial Intelligence Approach, Guanjin Wang, Hachem Bennamoun, Wai Hang Kwok, Jenny Paola Ortega Quimbayo, Bridgette Kelly, Trish Ratajczak, Rhonda Marriott, Roz Walker, Jayne Kotz

Research outputs 2022 to 2026

Background: Perinatal depression and anxiety significantly impact maternal and infant health, potentially leading to severe outcomes like preterm birth and suicide. Aboriginal women, despite their resilience, face elevated risks due to the long-term effects of colonization and cultural disruption. The Baby Coming You Ready (BCYR) model of care, centered on a digitized, holistic, strengths-based assessment, was co-designed to address these challenges. The successful BCYR pilot demonstrated its ability to replace traditional risk-based screens. However, some health professionals still overrely on psychological risk scores, often overlooking the contextual circumstances of Aboriginal mothers, their cultural strengths, and mitigating protective factors. This highlights …

Beyond My Control: The Role Of Sense Of Control On Cognitive Functioning And Depressive Symptoms In Older Adults, Sabine Lohmar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Depression and depressive symptoms commonly coincide with mild cognitive impairment (MCI) and dementia in older adults (Ismail et al., 2017; Panza et al., 2010), with its prevalence varying based on dementia severity, diagnostic criteria, and dementia subtype (Chi et al., 2015; Ismail et al., 2017; Leung et al., 2021; Lopez et al., 2003). This relationship is hypothesized to exist for a variety of reasons, including that depressive symptoms occur as an emotional response to cognitive functioning (Bennett & Thomas, 2014; Richard et al., 2013). Emotional responses may be explained by a decline in sense of control, or the belief in …

Social Support And Negative Affective Outcomes Among Older Adults: Does Valuing Autonomy Matter?, Erika Anne Fenstermacher

Graduate Theses, Dissertations, and Problem Reports (ETD)

While not a normal part of aging, depression is a concerning psychiatric condition in late life. Depression is a significant predictor of suicide and the highest rates of suicide occur in middle aged and older adult men. One factor that may protect against depression and suicidal behavior among older adults is social support. Social support has been demonstrated as a significant factor in health and well-being. Perceived social support has consistently been linked to beneficial outcomes, however, received support has mixed results with some studies even finding received support to be harmful. For individuals who highly value autonomy, it may …

The Moderating Effects Of Self-Compassion On The Relationship Between Shame And Depression In Military Populations, Sarah Foran

College of Graduate Studies: Theses & Dissertations

The U.S. Military has faced a continuous rise in mental health concerns reported by service members and veterans (Currier et al., 2017; Rosenheck & Fontana, 2007). Studies of military personnel have found that up to 15% of service members meet the criteria for experiencing depression (Shen et al., 2012). Often, individuals with military experience face numerous stressors that positively contribute to this experience of depression and feelings of shame (Bradbard et al., 2014; Litz et al., 2009). Military culture (often emphasizing shame related to mental health) has also been found to put military personnel at higher risk of experiencing depression …

Does Friend Groups’ Co-Rumination Explain Depression Homophily Among Undergraduate Women's Friendship Groups?, Alyssa D. C. Klas

College of Graduate Studies: Theses & Dissertations

The transition to college is a period known for changes in social support and increases in depression risk. Undergraduate women are particularly vulnerable to developing internalizing symptoms like depression in response to relational stressors and social norm pressures associated with college life. Co-rumination, defined as excessive and ongoing discussion about problems and emotionally distressing topics, both fosters connection and intimacy between friends and increases risk of depressive symptoms. Thus, relationships that are typically seen as buffers from depression may, paradoxically, contribute to risk when support-seeking becomes maladaptive. Most research on co-rumination’s effects is limited to friendship dyads. However, within larger …

Reply [To Burnout Reflections: Musings On Bianchi And Schonfeld’S Five Focal Areas], Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

Contrary to what one might assume, the burnout construct did not emerge from systematic research. The definition of burnout was formulated in the 1970s based on prenotions and anecdotal evidence. No sound empirical studies, no in-depth theoretical reflections, not even a review of the stress literature underpinned the introduction of the construct. It is thus unsurprising that some observers regard the edifice of burnout research with scepticism. The pioneers of burnout research neglected basic scientific standards and, by overlooking the abundant work of contemporary stress researchers, deprived themselves of important safeguards against illusions of novelty making big claims based on …

Barriers And Motivators To Attending Group Exercise Classes In Women With Anxiety, Depression And Post-Traumatic Stress Disorder, Sarah Ford

Theses: Doctorates and Masters

Research has demonstrated the positive effect of exercise on mental health disorders such as anxiety disorder, depression and post-traumatic stress disorder. Studies have also investigated the barriers and motivators that women in particular experience when contemplating the ways in which to engage in physical activity. However, a literature gap exists regarding women who experience anxiety disorder, depression and post-traumatic stress disorder, and the barriers and motivators that they specifically navigate when looking to attend group exercise classes. In this body of research for the award of Master of Medical and Health Science by Research, a scoping review was first conducted …
