The Relationship Between Body Mass Index And Depression In College Students, Bryn Kable

CMC Senior Theses

College student mental health has seen a serious decline over the last decade (Esaki-Smith, 2022). One factor that has been linked to both physical and mental disorders is obesity. A common way to operationalize weight is through body mass index (BMI) (Ilman et al., 2015). There is evidence that BMI and depression are correlated linearly in that individuals with higher BMIs have higher levels of depression (Badillo et al., 2022; Simon et al., 2008). The exact mechanisms of this relationship are still generally unknown; thus, the goal of this study was to investigate the relationship between BMI and depression in …

Oral Contraceptives And Affective Disorders: Neurobiology And Informed Choice, Sophia Mae Drezner

Scripps Senior Theses

Pregnancy prevention and female reproductive freedom have been some of the most contested political issues for decades. Abortion, a fundamental part of women’s healthcare, divides liberals and conservatives on an international scale. The consequences of unintended pregnancy without safe and reliable contraception are widespread, disproportionately impacting women of color, trans and non-binary folks, and poorer communities. The birth control pill is the most common form of oral contraception (OC) globally. Many people with ovaries begin the pill or other hormonal contraceptive (HC) methods as young as 11 years old. Exogenous progesterone and estrogen are known to impact mood, affect, physiology, …

At The Intersection Of Identity: An Exploration Of Sense Of Belonging And Depression, Kalah Brown

CMC Senior Theses

Belonging is vital to our well-being, health, and identity. At the same time, belongingness is tied so closely to our identity, such that our specific identity may influence the extent to which we feel that we belong, as well as moderating the relationship between belonging and mental health. This present study investigates whether intersectionality, how and if a person is a minority, moderates the relationship between belonging and depression. College students were administered the Beck’s Depression Inventory II and the General Belongingness Scale. They also filled out demographic information to capture their identity and levels of intersectionality. Both belonging and …

Respiratory Sinus Arrhythmia And Depressive Symptoms: Considering The Role Of Cultural Orientation And Fit, Akriti Poudel

CMC Senior Theses

The aim of this study was to examine the relationship between cultural orientation, respiratory sinus arrhythmia (RSA), and depression. Horizontal collectivism (HC) has been shown to be predictive of positive psychological adjustment (Oh, 2022; Schermer et al., 2023), but the extent to which the individual’s level of HC matches with the group is not well understood. RSA has traditionally been conceptualized as a measure of adaptive functioning; (Graziano & Derefinko, 2013; Qu & Leerkes, 2018, Hinnant et al., 2011) however, more recent research has proposed that RSA is better conceptualized as a marker of susceptibility to environmental influences (Sturge-Apple et …

Self-Distancing As A Persuasive Amplifier For Increasing Help-Seeking Among People With Depression, Sara M. Hollar

CGU Theses & Dissertations

People with high levels of depressive symptomatology report less favorable attitudes toward help-seeking and reduced help-seeking intentions than people with lower levels of depressive symptomatology. While some attempts to persuade people with depression to seek help have been successful, others have failed. Preliminary research using both perspective-taking and mental time-travel self-distancing writing tasks have shown potential. However, a video that asked people to think, rather than write, about help-seeking from a distanced perspective failed to increase help-seeking outcomes. This dissertation tests a new approach where participants are prompted to take a self-distanced approach while watching existing help-seeking video messages. In …

Social Support, Self-Esteem, And Levels Of Stress, Depression, And Anxiety During The Covid-19 Pandemic, Candace Ying Tsai

Scripps Senior Theses

The COVID-19 pandemic resulted in unprecedented disruptions to daily routines and social connections, which negatively impacted the mental health and well-being of many. Unsurprisingly, the most utilized coping strategy during the pandemic involved social support. However, those low in self-esteem seem to question others’ positive regard and continued acceptance, and overall perceive others’ behavior more negatively than those with high self-esteem (Murray, Holmes, et al., 1998). The proposed correlational study will examine the effects of social support and self-esteem on stress, anxiety, and depression during the COVID-19 pandemic, as well as investigate whether one’s self-esteem affects the influence that social …

Putative Mechanisms Underlying The Antidepressant Actions Of Ketamine: A Review And Study Proposal, Tristan Reece

CMC Senior Theses

Major Depressive Disorder (MDD) is a highly debilitating and common psychiatric disorder that affects over 250 million people globally; it is among the most financially and emotionally burdensome illnesses in the world. Currently approved antidepressants are suboptimal in their efficacy and latency of therapeutic action. In contrast, single administrations of sub-anesthetic ketamine have been shown to rapidly alleviate depressive symptoms within hours, even in treatment-resistant patients. Ketamine is believed to exert these effects by increasing glutamatemediated neurotransmission and promoting rapid neurotrophic factor release, restoring the integrity of neural circuits that are compromised in depression. However, uncertainty surrounding its specific antidepressant …

The Association Between Social Capital And Depression, Abdulrahman Abudawood

CGU Theses & Dissertations

Mental health is an integral component of a healthy and balanced life, and deterioration in mental health has a significant impact on the quality of life. Being an active member of the community can positively impact personal mental health and emotional wellbeing. The World Health Organization (WHO) considers Social Capital (SC) a significant determinant of individual mental health. Despite that, there are limited studies analyzing the association between SC and the prevalence or severity of depressive symptoms experienced by suburban residents of the United States. This study aimed to assess the relationships between the six dimensions of SC introduced by …

The Effects Of Retirement On Division Iii Collegiate Athletes' Mental Health, Laura Dickinson

CMC Senior Theses

Following their participation in athletics after their collegiate retirement, this research examines whether there is a relationship between college athletes' mental health and their athletic identity. Specifically, it examines whether athletic retirement leads to anxiety and depression. Participants will be asked to answer a survey that relates to their athletic identity, and the occurrence of symptoms related to depression and anxiety at different periods of their collegiate career and after their athletic retirement. Results are predicted to demonstrate a significant relationship between retired athletes’ level of athletic identity and the prevalence of depression and anxiety following cessation of athletics. However, …

Patients' Expectations' Effects On Treatment Outcome In Major Depressive Disorder (Mdd) In Intensive Short-Term Dynamic Psychotherapy (Istdp), Taylor Kahn

Scripps Senior Theses

Existing research has supported the influence of patients’ expectations on symptom reduction in both antidepressant trials and cognitive behavioral therapy (CBT) for individuals suffering from major depressive disorder (MDD). Intensive short-term dynamic psychotherapy (ISTDP) is effective in treating individuals with MDD, and its structured sessions, similar to the replicable format of CBT, offer a valid psychodynamic therapy that can be compared to past CBT research. This study will attempt to examine whether patients’ expectations will affect equal or greater symptom reduction when being treated with ISTDP than if treated with CBT. It will also examine whether patients’ expectations affect the …

I’M Sexy And I Know It: The Impact Of Sexual Self-Esteem And Body Satisfaction On Disordered Eating Behavior, Marissa Parks

Scripps Senior Theses

Rates of dieting, disordered eating, and eating disorders are continuing to rise in the United States. Many factors influence decisions to engage in problematic eating, including body satisfaction and self-esteem. This paper outlines two studies that examined these relationships and proposed an intervention to reduce disordered eating. In the first study participants were primed to think about a time when they had negative thoughts about their intelligence, their body, or their sexual self-esteem and then measured body image avoidance, self-esteem, sexual self-esteem, disordered eating behaviors, well-being, and depressive symptoms. Consistent with previous research, it was found that having participants recall …

An Extension Of The Savoring Approach To Increasing Help-Seeking For Depression: Reducing Self-Focus Through A Writing Task And Savoring Psa, Tasha Straszewski

CGU Theses & Dissertations

Past depression mass media campaigns have been utilized to increase mental health literacy, decrease stigma, or a combination of the two. However, among these campaigns, some have not been effective, and some have resulted in iatrogenic effects (see Gulliver, Griffiths, & Christensen, 2010, for examples of both). In hopes of improving the effectiveness of depression campaigns, laboratory studies have utilized persuasion approaches to increase help-seeking among individuals with heightened depressive symptomatology. More recently, Siegel and Thomson (2016) turned to the utility of infusing individuals with positive emotion to increase help-seeking intentions (i.e., positive emotion infusions; PEIs) and found initial success …

The Effect Of The Change In Call Loan Rates And Volatility On Stock Returns In 1929: An Empirical Study Into A Determinant Of The Great Depression, Amberish Chitre

CMC Senior Theses

I investigate the effect of the change in call loan rates on stock returns during 1929. Call loan rates are the interest rates on borrowed funds to trade equity on a given exchange. It is estimated that 40% of stocks during this period were bought on margin. After a price decline comes a margin call, followed by a forced sales of securities, which leads to additional margin calls and future price declines. I regress daily excess returns on the change in daily call loan rates during 1929. In addition, I estimate volatility using an ARCH model and observe the previously …

Perceived Social Support And Suicide-Related Depression Symptom Clusters Among Queer College Students, John Kellerman, Daniel Krauss

CMC Senior Theses

LGBTQ+ individuals report disproportionately high rates of depression and suicidal behaviors compared to the general populations, particularly among queer youth. Certain depressive symptoms and symptom clusters, namely hopelessness and self-blame, are predictive of suicidal behavior and outcomes. In contrast, perceived social support may act as a buffer against suicide ideation. The disparity in the rate of queer suicidality may be predicted by higher rates of hopelessness and self-blame, as well as lower rates of perceived social support among depressed queer youth in comparison to depressed non-queer youth. The current study will test this hypothesis using a sample of depressed queer …

Log Kya Kahenge: Psychological Well-Being And Perceived Stigma In The South Asian American Community, Khushboo Jain

Pomona Senior Theses

Current research has independently studied depression, stigma, and coping mechanisms in relation to culture, yet the effects of perceived stigma on the relationship between depression and control coping are heavily understudied. Typically, studies have broadly focused on comparing eastern and western cultures, but have not analyzed how populations with mixed cultural influences experience depression and stigma and further engage in control coping mechanisms. This study thus explores how perceived stigma moderates the relationship between depressive symptoms and control coping mechanisms for South Asian Americans. The study hypothesizes that the level of perceived stigma will moderate the relationship between depression and …

A Link Between Gut Microbes & Depression: Microbial Activation Of The Human Kynurenine Pathway, Christina Cobb

CMC Senior Theses

Our gut microbiota is involved in human development, nutrition, and the pathogenesis of gut disorders, but has more recently been implicated as a possible mechanism in the pathophysiology of several brain disorders, including disorders of mood and affect, such as depression. Researchers have referred to this dynamic, bidirectional signaling pathway between the gut and the brain as the “gut-brain axis.” However, most research on this axis has been limited to rodent studies, and there has been little insight into the mechanism behind it. I propose that the kynurenine pathway, where tryptophan is converted to kynurenine, is a compelling mechanism mediating …

Healing From Racism With Compassion Meditation: Effects Of Coping On Mental Health, Courtney Chan

CMC Senior Theses

This study examines whether Compassion Meditation (CM) can help ethnic minority college students heal from race-related stress. The present study hypothesized that through participation in a CM intervention, the augmentation of adaptive coping strategies (i.e., self-compassion) and the reduction of maladaptive coping strategies (i.e., internalization, defined as self-blame, and detachment, defined as social isolation) would reduce depression and PTSD. Participants (N = 9) participated in an 8-session weekly CM intervention and completed three questionnaires at the beginning, middle, and end of the intervention. Results demonstrated that increasing self-compassion predicted decreases in depression, and that reducing coping via detachment predicted …

Polarizing Narratives: Harmful Representations Of Mental Illness And Bipolar In Popular Media, Mary Jane Coppock

Scripps Senior Theses

Representations of mental illness in mainstream media have historically been infantilizing and dangerous. In the last century, dominant media has perpetuated inaccurate and damaging tropes about bipolar disorder in particular, perpetuating misunderstanding and stigma. Despite this fact, art can provide an outlet through which healthy images that promote understanding and sympathy can be dispersed. My project, Polarized, presents a more accurate representation of the disorder and its effects on individuals who struggle with it, as well as their loved ones. Bipolar disorders are a group of mental illnesses that cause dramatic shifts in an individual’s mood, energy, thinking ability, and …

Social Comparison And Self-Presentation On Social Media As Predictors Of Depressive Symptoms, Janet L. Uhlir

Scripps Senior Theses

Social media, an online arena for social behaviors such as self-presentation and social comparison, may have effects on users’ mood and mental health. Favorably presenting oneself is linked to positive outcomes such as higher self-esteem, whereas social comparison, in general and specifically upward social comparison to higher-performing others, is related to feelings of inadequacy, envy, and depression. Social comparison may explain the “Facebook depression effect,” acting as a mediator between time spent on social media and depressive symptoms. A correlational study is proposed that will ask 200 participants to report their time spent on various social media sites, self-presentation of …

It's Worse Than We Think: Why It Matters That We Underestimate Depression, Tess Hubbeling

CMC Senior Theses

This paper will examine specific processes involved within the decision-making process of how to allocate limited health care resources. I will start by discussing how in order to compare and differentiate between health states, we have created ranking systems, based on the health state’s impact on people’s quality of life, which health states need more care, and which can be most effectively treated. We evaluate impact on quality of life by assigning quality weights to years of life lived with that health state, which we call quality-adjusted life years, or QALYs.

Next, I will discuss the problems with assigning quality …

Sceletium Tortuosum And Mesembrine: A Potential Alternative Treatment For Depression, Rebecca Schell

Scripps Senior Theses

Major depressive disorder affects people’s productivity and ability to function in everyday life. The disorder can be attributed to neurochemical imbalances of various neurotransmitters including but not limited to serotonin, dopamine, and norepinephrine. Conventional pharmacological treatments have focused primarily on these three neurotransmitters, and have been shown to be effective in alleviating most of the major symptoms of depression. Although these treatments are effective with most patients, they are known to have adverse side effects, causing patients to seek alternative treatments. Sceletium tortuosum, a succulent plant found in the Cape region of South Africa, has been shown to have …

The Relationship Between Adolescent Depression And Social Skills In Young Adulthood, Emily H. Simmons

Scripps Senior Theses

This study investigated the relationships between a history of adolescent depression and social skills in young adulthood. Participants between the ages of 22 and 30 reported past and present experiences with depression and completed assessments of three aspects of social skills: emotional understanding, strength of social relationships, and interpersonal competence. Results indicated an association between current depression and social skills deficits but no main effect of adolescent depression on overall social skills. However, greater emotional understanding was associated with a history of adolescent depression. An earlier age of onset predicted stronger social relationships while length of depressive episode and time …

Applying The Biopsychosocial Model: Factors Associated With Depression In Mexican-American Adults, Alison B. Ross

Scripps Senior Theses

Although professionals in psychiatry, psychology and medicine claim to endorse the biopsychosocial model as proposed by George L. Engel (1977), clinicians in all three fields still tend to underutilize it. Some academics have also criticized the model for its inadequate emphasis on cultural contextualization. To improve upon the model, I sought to empirically establish the relationship between culturally-specific social factors and psychological disorder, in this case depressive symptoms in Mexican-American adults. Eighty-six Mexican-American participants living on the US-Mexico border completed scales measuring depressive symptoms, bidirectional acculturation, living situation, diabetes, and health beliefs regarding the origins of diabetes. The results revealed …
