Exploring The Links Between Social Anxiety And Depression In The Maintenance Of Romantic Relationships, Christian M. Hahn

Electronic Thesis and Dissertation Repository

Social anxiety is characterized by fear and avoidance of social encounters and has recently been associated with a variety of difficulties in romantic relationships. Complicating further investigation of these associations is the high degree of comorbidity between social anxiety and depressive symptomatology, which share several similarities in expression despite disparate underlying causes. The present thesis examines the unique influences of social anxiety and depression on a number of central aspects of relationship functioning and provide the first longitudinal investigation of the impacts of actor and partner social anxiety and depression on relationship quality and functioning. In Study 1, three independent …

Baseline And Stress-Induced Cognitive Control Deficits And Pro-Inflammatory Cytokines In Currently, Remitted, And Never Depressed Individuals, Katerina Rnic

Electronic Thesis and Dissertation Repository

Background: Cognitive theories posit that cognitive control deficits promote depression by reducing ability to self-regulate under stress. When activated by stress and accessible to working memory, negative cognitive content and structure (i.e., schemas), may interfere with cognitive control abilities, resulting in even greater declines in executive functioning. Moreover, burgeoning evidence indicates that social stress upregulates inflammation, resulting in a pro-inflammatory phenotype that drives depression pathogenesis. However, cognitive mechanisms underlying this process are not well understood. An objective of this study was to examine depression-related deficits in cognitive control and their association with poor self-regulation. Another purpose was to evaluate the …

The Role Of Social Disconnection In The Relationship Between Perfectionism And Psychological Distress, Samantha Chen

Electronic Thesis and Dissertation Repository

This dissertation investigated the interpersonal mechanisms through which various aspects of perfectionism confer risk for psychological outcomes. Three studies were conducted based on the Perfectionism Social Disconnection Model (Hewitt, Flett, & Mikail, 2017), which proposes that individuals with higher levels of perfectionism may experience significant social disconnection, which then lead to a variety of maladaptive outcomes. Study 1 examined the longitudinal impacts of trait perfectionism and sense of relatedness on the variance in change in psychological outcomes. Findings showed that negative perceptions of relatedness partially mediated the link between socially prescribed perfectionism and psychological distress three months later; however, this …

A Study Of Multiple Predictors Of Cognitive Fatigue In Individuals With Multiple Sclerosis, Leila M. Mackay

Electronic Thesis and Dissertation Repository

Persons with multiple sclerosis (PwMS) commonly experience cognitive fatigue (CF), defined as a decrease in cognitive performance over a sustained activity and measured objectively or subjectively. In the present research, we evaluated the extent to which depression, anxiety, information processing speed, sleep quality, and disease severity predict subjective and objective CF, in a sample of 55 PwMS (37 females, M = 44.23). Although no statistically significant predictors of objective CF were demonstrated, all variables predicted subjective CF, R2adj = .384 [F (6, 40) = 5.783, p = .0002]. In particular, depression and information processing speed were found to be significant …

A Dyadic Partner-Schema Model Of Relationship Distress And Depression: Conceptual Integration Of Interpersonal Theory And Cognitive-Behavioral Models., Jesse Lee Wilde, David J. A. Dozois

Psychology Publications

Difficulties in romantic relationships are a prominent part of the disorder for many individuals with depression. Researchers have called for an integration of interpersonal and cognitive-behavioral theories to better understand the role of relational difficulties in depression. In this article, a novel theoretical framework (the dyadic partner-schema model) is presented. This model illustrates a potential pathway from underlying "partner-schema" structures to romantic relationship distress and depressive affect. This framework integrates cognitive-behavioral mechanisms in depression with research on dyadic processes in romantic partners. A brief clinical case example is presented to illustrate the utility of the dyadic partner-schema model in conceptualizing …

The Role Of Cognitive Distortions In The Longitudinal Relationship Between Problematic Drinking And Depressive Symptoms, Monica F. Tomlinson

Electronic Thesis and Dissertation Repository

This dissertation investigated the mechanisms by which problematic drinking contributes to depressive symptoms in two longitudinal, prospective, cohort-design studies. Distorted cognitive processes (dysfunctional attitudes, negatively-biased information processing, and rumination) were proposed as mediators in the relationship between problematic drinking and depressive symptoms over time. Study 1 (N = 1090) assessed participants’ levels of problematic drinking, dysfunctional attitudes, and depressive symptoms at three-month intervals for one year. Findings indicated that the social and occupational consequences of alcohol use (e.g., interpersonal conflict) significantly predicted depressive symptoms. The amount and frequency of alcohol consumption did not. Therefore, impairment, but not level of …

A Randomized Controlled Trial Of Internet-Delivered Cbt And Attention Bias Modification For Early Intervention Of Depression, R. Mcdermott, David J. A. Dozois

Psychology Publications

Abstract

The conceptualization and empirical knowledge base related to major depression has increased dramatically in recent years. We now have well-developed and validated models of depression from a range of theoretical perspectives. These models have significantly enhanced the development of effective treatments and preventative interventions. Although various prevention programs are available, Web-based protocols can enhance accessibility to evidence-based prevention programs. The current study involved a randomized controlled trial focused on the prevention and treatment of depression in high-risk first- and second-year undergraduate students. Three Internet-delivered preventative programs were compared: cognitive behavioral therapy (CBT; MoodGym), attentional bias modification, and an active …
