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 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 …

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 …

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 …

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 …
