Biological Stress Response And Cognitive Vulnerability To Depression In Adolescence, Bridget M. Brush Aug 2018

Biological Stress Response And Cognitive Vulnerability To Depression In Adolescence, Bridget M. Brush

College of Science and Health Theses and Dissertations

Depression is the leading cause of worldwide disability. Rates of Major Depressive Disorder (MDD) increase exponentially over the adolescent transition, suggesting adolescence represents a key period of risk for the onset of depression. Previous research has associated both biological stress response and cognitive vulnerability with symptoms of depression; however, there is little research examining the joint effects of these two risk factors and symptoms of depression, especially during adolescence. The present study examined the association between symptoms of depression and two established risk factors for depression: cognitive vulnerability, as measured by negative cognitive style, and biological stress response, as measured ...

Meaning As A Buffer Against Adolescent Psychopathology, Ellen Shaina Dulaney

College of Science and Health Theses and Dissertations

This thesis investigates the function of meaning in life in adolescence to ascertain whether specific psychological resources may protect youths against threats to subjective well-being. Meaning in life and the search for the meaning in stressful occurrences were independently examined for their influence on stress impact and depression symptomatology. 201 American middle-school and high-school students between 12 and 19 years of age were recruited for this study. Participants reported on questionnaires targeting frequency of negative life events; depressive symptoms; sense of meaning; and tendency to reframe stressors in terms of their meaning, termed “stressor meaning seeking”. It was expected that ...


Exposure To Community Violence And The Trajectory Of Internalizing And Externalizing Problems In A Sample Of Low-Income Urban Youth, Jeremy Jay Taylor Aug 2013

Exposure To Community Violence And The Trajectory Of Internalizing And Externalizing Problems In A Sample Of Low-Income Urban Youth, Jeremy Jay Taylor

College of Science and Health Theses and Dissertations

Intro: The transition from childhood to adolescence is a period of increased risk for psychological problems (e.g. Keiley, & Martin, 2002). Exposure to community violence, may impact the degree to which psychological problems emerge during adolescence (Grant et al., 2004). Previous research also indicates that low-income urban youth are disproportionately exposed to severe community violence, leaving them at higher risk to experience psychopathology (Grant et al., 2004). However, recent longitudinal research suggests that this elevated risk may decline throughout the adolescent years (Murphy et al., 2000) especially for internalizing problems (J. Twenge & S. Nolen-Hoeksema, 2002). The current research hypothesizes that ...
