Neuroticism And Stressful Life Events: Probing Mechanisms Underlying Vulnerability To Stress-Related Depression, Erin Bondy
Arts & Sciences Electronic Theses and Dissertations
Elevated neuroticism (N) potentiates the depressogenic effects of stressful life events (SLEs). We first replicate this association using longitudinal data (N=971 older adults) from the St. Louis Personality and Aging Network (SPAN) study. Here, SLEs prospectively predicted future depressive symptoms, especially among those reporting elevated N, even after accounting for prior depressive symptoms and previous SLE exposure (NxSLE interaction: p=0.016, ΔR2=0.003). These findings were further replicated in cross-sectional analyses of the Duke Neurogenetics Study (DNS), a young adult college sample with neuroimaging data (n=1,343: NxSLE interaction: p=0.019, ΔR2=0.003). Because evidence suggests that stress may promote depression …

The Role Of Personality In The Development Of Health Disparities During Late-Mid Life, Juliette Mcclendon Iacovino
Arts & Sciences Electronic Theses and Dissertations
Objectives: The current study examined race/gender disparities in initial levels and trajectories of self-reported physical and mental health, and health care utilization, as well as the impact of personality and stressful life events on race/gender disparities. We hypothesized that health disparities would remain stable or decrease over time; that at-risk personality traits (e.g., high neuroticism) would have a more robust negative impact on health for black participants; that trust would mediate racial disparities in health; and that personality traits would moderate the association between stressful life events and health trajectories differentially across race/gender. Methods: Analyses utilized the first six waves …
