Unity Against Adversity: Examining The Moderating Effect Of A Sense Of Community Between Discrimination And Discrimination-Related Distress Among Racial And Ethnic Minoritized Adults, Kimberly Velazquez

Dissertations and Theses

Background: Racial and ethnic minoritized populations are significantly more likely to develop mental health conditions, such as depression, anxiety, and posttraumatic stress disorder, than White populations. Some of the predominant causes are rooted in the impact of discrimination, and other social determinants of health (SDOH), including adverse experiences. Studies found that discrimination can lead to a distinct form of anxiety described as discrimination-related distress, which has a higher negative association with poor mental health symptoms. It has been suggested that having a strong sense of community (SOC) –a collective sentiment shared by community members regarding their membership, feelings of belonging, …

Competitive And Facilitative Interactions Between Pavlovian Cues In Human Associative Learning: A Behavioral And Neural Analysis, Fahd Alhazmi

Dissertations, Theses, and Capstone Projects

Learning to anticipate significant events accurately is a crucial element of survival for all species. The process by which animals acquire this knowledge has been a central question of psychological research. A fundamental assumption of many learning theories is that the predictive value assigned to cues is not simply determined by their probability of reinforcement but rather by their ability to compete with other cues present during learning. The assumption of cue competition has significantly contributed to the development of behavioral and neuroscience research for decades, as it has opened the door to new empirical and theoretical advances on the …

Investigating Steady State Visually Evoked Potentials As A Novel Biosignature For Anxiety-Related Attention Bias, Elizabeth R. Davis

Dissertations, Theses, and Capstone Projects

Anxiety-related attention bias (AB), a type of cognitive bias underlying the development and maintenance of anxiety disorders, is typically defined as exaggerated attention towards threat; however, some individuals also demonstrate AB away from threat and in some instances, no detectable AB at all. Debate about the reliability and validity of AB behavioral measures has prompted examination of additional assessment methods. Neurophysiological methods, such electroencephalography (EEG), have yielded encouraging early findings. The steady-state visually evoked potential (SSVEP), a measure of selective visual attention derived from EEG, holds promise as a biosignature for AB. Research documents heightened SSVEP power to emotionally salient …

A Parar Para Avanzar: To Stop/To Stand/To Strike To Advance, Christina N. Barrera

Theses and Dissertations

This paper presents the first fragments of a political framework outlining how I situate my work, which lives between “craft” and “art” models of making and between colonized and colonizing traditions. My writing proposes ways of making and being informed by practices, strategies, and organizing that work towards greater autonomy and liberation under these conditions.

The Feasibility Of Remote Brief Mindfulness Training And Impact On Anxiety-Related Attention Bias, Hanna Culang

Theses and Dissertations

Brief mindfulness training (BMT) improves anxiety and the allocation of attentional resources. Whether BMT can remediate disruptions in attention associated with anxiety, such as anxiety-related attention bias (AB), remains unclear. This experimental study revealed that BMT significantly improved subjective state mindfulness and state anxiety, but did not influence AB.

Pondering Possible Psychological Pandemonium: Covid-19’S Impact On Undergraduate Students’ Distress Levels, Laura Alarcon

Student Theses

The pandemic has altered everything in its path, including a broad impact on mental health, but not everyone has been affected equally. The COVID-19 pandemic presents an opportunity to examine if previously found differences in how non-Hispanic white and Latinx populations experience anxiety persist and/or were compounded. This study investigated distress levels of Latinx and non-Hispanic white undergraduate students at a public Hispanic Serving Institution both prior to and during the pandemic. A two-way ANOVA was run on a subset of an existing database to assess changes in distress levels between the two populations and timeframes. It was hypothesized that …

Covid-19 Vaccine Related Anxiety Partially Mediates The Association Between Covid-19 Related Anxiety And Student Adjustment To College During The Pandemic, Hanh Nguyen

Dissertations and Theses

The COVID-19 pandemic caused severe disruptions to the education of millions of college students, who were forced to adapt to sudden changes in living and learning environments. In this study, we sought to investigate two different dimensions of anxiety that were specific to the pandemic – COVID-19 related anxiety and COVID-19 vaccine anxiety – hoping to pinpoint the relationship between these two variables and students’ ability to adapt to college. Specifically, using cross sectional survey data during three semester waves (Spring 2021, Fall 2021, and Spring 2022) we hypothesized (1) a decreasing trend across time in both COVID-19 related anxiety …

Piled Up, Sophia Lebowitz

Capstones

Piled Up is a 10 minute film about Anna Sacks, a dumpster diver in New York City who has recently found viral social media fame for calling out wasteful corporate practices. Meanwhile, the physical build-up of the trash she collects, and the anxiety of the never-ending cycles of waste are weighing her down and keeping her from her goals.

This is a surprising story about a woman who has found overwhelming social media success while simultaneously dealing with the mechanism of that success, waste, building up in her life. Her videos have garnered her thousands of followers and millions of …

Targeting Ampa Receptor Modulation During Early Life Adversity: A Mediator For Threat Associated Memories, Roseanna M. Zanca

Dissertations, Theses, and Capstone Projects

Early life adversity (ELA) is the exposure to a single or to multiple traumatic events before the age of 18 that go beyond the child’s coping. These adverse events are often exacerbated during adolescence particularly when cognitive performance is compromised. Adolescents who experienced ELA may show symptoms of post-traumatic stress disorder (PTSD), while not vividly recalling the early life trauma. These individuals show atypical connectivity between prefrontal-amygdala and hippocampus, all of which is associated with an increased risk of experiencing a traumatic event again later in life. While clinical research has increasingly stressed the importance in addressing the long-lasting consequences …

Learning To Feel Safe: A Translational Study Of The Influence Of Safety Learning On Anxiety-Related Overgeneralized Fear, Hyein Cho

Dissertations, Theses, and Capstone Projects

Anxiety disorders are among the most common mental health diagnoses, affecting about a third of the population in their lifetime. However, approximately a third of individuals with anxiety do not respond to current treatment approaches, highlighting the need to identify additional potential therapeutic mechanisms. Safety learning is one such mechanism, but methodological challenges and a dearth of research have prevented the field from advancing the understanding of the role of safety learning in the etiology and remediation of anxiety disorders. Animal research, using single-cued safety learning paradigms, has yielded promising early findings, demonstrating that safety learning directly reduces anxiety-related behaviors …

The Joint Influence Of Social Support And Coping On Anxiety In Aya Cancer Survivors, Genevieve Durso

Theses and Dissertations

Background Adolescent and young adult (AYA) cancer survivors experience unique psychosocial needs during remission. Cancer-related anxiety is endemic amongst AYA survivors and can impede upon the survivor’s life post-cancer treatment. Independent of one another, confiding in a social support system and frequent engagement in coping mechanisms benefit those throughout the cancer experience, leading to more positive psychosocial outcomes. Hypothesis The dual utilization of one’s social support network and coping mechanisms would reduce cancer-related anxiety in AYA cancer survivors. Methods This study’s data was derived from a prior study conducted at Memorial Sloan Kettering Cancer Center, consisting of 128 adolescent and …

Does Resilience Moderate The Impact Of Children’S Experiences Of Racial And Ethnic Discrimination On Internalizing Problems?, Dahlia Abbas

Dissertations and Theses

This study’s objectives were to investigate how children’s experiences of discrimination impact the severity of their internalizing symptoms, and whether the relation between discrimination and internalizing symptom severity is moderated by resilience. It was predicted that children who had experienced more discrimination would have more severe internalizing symptoms, especially when they have low levels of resilience. Children [N=20; Mean (SD) age= 11.83 (2.50)] receiving low-cost music lessons in northern Manhattan were recruited into a larger study examining how learning music affects cognitive and emotional development. Children were interviewed in-person about experiences of discrimination because of their race/ethnicity using the Perceptions …

Does Overweight/Obesity Moderate The Association Between Adhd And Internalizing Difficulties In Young Adults?, Breanna Badripersaud

Dissertations and Theses

This study’s objective was to investigate if ADHD symptoms and BMI are associated with internalizing impairments of depression, anxiety, stress and lower self-esteem in college students. It was predicted that higher ADHD symptoms would be associated with elevated depression, anxiety, stress, and low self-esteem, especially if BMI fell in the overweight/obese range. Undergraduate students [N= 580; Mean (SD) age= 20.7 (3.10)] from an urban campus completed an online survey comprising self-report measures of demographics, height/weight, attention and hyperactivity/impulsivity (Barkley Deficits Executive Functioning Scale ADHD- Executive Function Index), depression, anxiety, stress (all using the Depression Anxiety and Stress Scale) and self- …

Diet, Inflammation, Gut Microbiome, And Mental Health, Ashley R. Polokowski

Dissertations, Theses, and Capstone Projects

Omega-3 fatty acids (ω-3 FAs) are an essential fatty acid necessary for healthy development in mammals. They possess anti-inflammatory properties and have more recently been shown to impact gut microbiota, both factors hypothesized to be associated with depression and anxiety. Thus, empirical efforts have begun to examine the benefit of ω-3 FAs as a treatment option for various psychological disorders. Although there is evidence that ω-3 FAs have favorable outcomes on depressive symptoms, the relationship between ω-3 FAs and anxiety and the pathways by which ω-3 FAs produce beneficial health effects are poorly understood. Both inflammation and the gut microbiome …

The Impact Of Racial Microaggressions And Major Discriminatory Events On Mental Health, Florence Lui

Dissertations, Theses, and Capstone Projects

The current study, a secondary data analysis, sought to determine the number and nature of latent groups for experiences of spectrum racial discrimination (i.e., both major and microaggressive racial discrimination) in a sample of emerging adults from a people of color (POC)-majority public university setting in the United States, and to understand the role of socio-demographic variables in defining each group. In addition, the study aimed to ascertain the extent to which endorsing spectrum racial discrimination experiences predicted anxiety and/or depression above the effects of general, non-race-related stress. Finally, the analyses gauged the mediating and/or moderating role of coping in …

The 5-Ht1a-R Knockout Mouse As A Model Of Later Life Anxiety Disorders: Implications For Sex Differences, Tatyana Budylin

Dissertations, Theses, and Capstone Projects

Anxiety affects nearly twice as many women as it affects men across all cultures and economic groups. Importantly, girls have a higher chance of inheriting anxiety disorders than boys, and many anxiety disorders appear at a very young age. However, little is known about sex differences in brain and behavioral development and how they relate to anxiety in adulthood. Serotonin 1A receptor (5-HT_1A-R) mediated signaling has been implicated in depression and anxiety, however most studies that focus on the involvement of the 5-HT_1A-R have been conducted in adults. Little is known about how the 5-HT_{1A …}

The Impact Of Working Memory Load And Anxiety On Attention Bias Modification Training, David Lloyd Yap

Theses and Dissertations

The effect of attention bias modification training (ABMT) on anxiety-related attention bias (AB) in a large (N=204) non-clinical sample was sensitive to working memory load (WML). ABMT produced expected changes in AB in the low-WML, low-anxiety group only. High WML and high anxiety alone and in interaction disrupted ABMT.

Ck2 Negatively Regulates 5-Ht4 Receptor Signaling In The Prefrontal Cortex And Mediates Depression-Like Behaviors, Julia Castello Saval

Dissertations, Theses, and Capstone Projects

The serotonergic system has been the major candidate in the pathophysiology of mood related disorders such as anxiety and major depressive disorder (MDD). Unfortunately, current antidepressant drugs are ineffective in 50% of the population and require chronic administration for a period of 3-6 weeks before the onset of therapeutic response. 5-HT4 receptor (5-HT₄R) agonists have emerged as potential candidates for fast antidepressant action, since an antidepressant response can be achieved after 3 days of pharmacological administration in rodents.

This dissertation aims to investigate the role of casein kinase 2 (CK2) as a regulator of 5-HT₄R expression …

Novel Biobehavioral Methods For Assessing The Anxiety-Related Attention Bias, Samantha Denefrio

Dissertations, Theses, and Capstone Projects

Anxiety disorders will affect an estimated one in three Americans, significantly impacting emotional health and quality of life. High personal and economic costs make research on the etiology, maintenance, and treatment of anxiety a crucial public health goal. Selective and exaggerated attention towards threat, termed attention bias (AB), has been identified as a core behavioral and neurocognitive mechanism in anxiety. A novel treatment, attention bias modification training (ABMT), targets AB and aims to ameliorate anxiety. Rarely acknowledged, however, are the challenges in the conceptualization and measurement of AB. First, associations between anxiety and AB in anxious populations have been increasingly …

Addicted To The Answer, Charumathi Raman

Capstones

Hypochondria, which is now broadly known as health anxiety, is the fear of a serious illness that continues despite evidence to the contrary from laboratory tests and the reassurance of physicians. In the past people with this disorder would go from doctor to doctor seeking an answer, but now many people rely solely upon online information.

For people with health anxiety, the Internet provides a lot of fodder. Researchers have recently coined the term "cyberchondria" to describe the phenomenon of increased health anxiety due to online health searches.

Entering questions like “Who started World War Two?” or “Who was the …

Threat-Related Attentional Bias In Relation To Anxiety And Depressive Symptoms In The General Population: The Potential Role Of Sex Effects, Beril Yaffe

Dissertations, Theses, and Capstone Projects

Heightened sensitivity to relevant environmental stimuli (attentional bias) has been observed in relation to clinical and non-clinical anxiety and depression symptoms. While depression symptoms are associated with sensitivity to disorder and self-relevant words, hypervigilance to threatening stimuli is observed in relation to anxiety symptoms. Furthermore, attentional bias has been shown to play an important role in the development and maintenance of depressive and anxiety disorders. Accordingly, a large body of literature has examined threat-related attentional bias in relation to symptoms of anxiety and depression. However, several methodological inconsistencies exist across studies, including variability in definitions of threat, lack of consideration …

The Influence Of Visibility On Mental Health Amongst The Muslim Female Population In The United States, Sarika Antora

Theses and Dissertations

Physiological Correlates Of Affective Decision-Making In Anxiety And Depression, Louisa I. Thompson

Dissertations, Theses, and Capstone Projects

Improving our understanding of cognitive and physiological profiles in anxiety and depression has the potential to reveal novel ways to target and improve treatments for these prevalent mental health conditions. The present study examined the impact of self-reported anxiety and depression symptoms on three established decision-making measures, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), Balloon Analogue Risk Task (BART; Lejuez et al., 2002), and Game of Dice Task (GDT; Brand et al., 2005), in a diverse sample of 100 college students (age 18 to 35). Physiological measures of tonic heart rate variability and galvanic skin response …

A Tale Of Two Tasks: Comparing Steady-State Visually Evoked Potentials With The Dot Probe As Measures Of The Anxiety-Related Threat Bias, Aqib J. Chowdhury

Theses and Dissertations

The present study explored how the anxiety-related threat bias (TB) measured by the dot probe is associated with steady-state visually evoked potentials (ssVEPs). ssVEPs were not significantly correlated with TB measured by the dot probe, suggesting that the dot probe and ssVEPs may index distinct components of attention to threat.

Sex Differences In The Anxiety Effects Of Cannabinoids, Helen T. French

Dissertations, Theses, and Capstone Projects

Aim: Anxiety disorders are twice as common among women, and those with anxiety disorders are 2-3 times more likely to have a substance abuse disorder than the general populace. However, little data exists on the sexually dimorphic effects of cannabinoids. In male humans and rodents, low acute doses of cannabinoids are anxiolytic while high and/or chronic doses are anxiogenic. In the dose response curve (DRC), we examined whether the biphasic effects of cannabinoids observed in males are also present in females. In the CB1R antagonism study, CP55,940-induced CB1R activation was antagonized via the CB1R-selective antagonist rimonabant to test the hypothesis …

Medication Management In Pediatric Chronic Illness: Should Patient Anxiety Be Considered?, Claire J. Hoogendoorn

Dissertations, Theses, and Capstone Projects

Introduction: There is growing support that psychological symptoms can impact various aspects of disease, well-being, and medical treatment for those with a chronic illness like Crohn’s disease (CD). Yet, almost no studies have examined whether psychological symptoms can influence management or efficacy of patient medication regimens. The aims of this project were to examine whether anxiety predicted pediatric patients’ level of medication management, medication prescription changes, and corticosteroid prescription and duration.

Method: A total of 105 pediatric patients ages 8-18 (M=14.5, SD=2.3) completed a validated anxiety questionnaire during a GI office visit (baseline). Prescribed IBD …

Feminine Ideology, Relational Self-Concept, And Internalizing Symptoms In Women, Anjali George

Dissertations, Theses, and Capstone Projects

Background: Investigators have theorized that women may experience internalizing disorders such as depression and anxiety more frequently than men in part because of unique socialization processes that women undergo. One aspect of early socialization thought to contribute to women’s propensity for depression and anxiety is the way women are brought up to relate to themselves in relation to others, often placing greater importance on the needs, desires, and value of others, at times at a psychological cost to themselves. This study attempts to elucidate the relationship between gender socialization, relational self-concept, and internalizing symptoms in women.

Methods: Two hundred and …
