Abstract

Prior trauma, current stress, and poor social support contribute to youth mental health problems. As daily stressors often increase in the aftermath of traumatic events, trauma could plausibly impact psychopathology not only directly but also indirectly via ongoing stress. In this study, we examined the relative roles of trauma and daily stressors in mental health outcomes in 753 Sri Lankan adolescents residing in areas impacted by the 2004 tsunami. In 2008, participants completed measures of trauma exposure, daily stressors, social support, posttraumatic stress symptoms (PTSS), emotional and behavioral problems (EBP), and functional impairment; a subsample (n = 89) repeated these assessments 16 months later. Regression models revealed positive associations between cumulative trauma and all three mental health measures. Significant variance in these associations could be explained indirectly, via daily stressors. For PTSS, the indirect effect accounted for 26.1% of the total effect of trauma, unstandardized coefficient ab = 0. 739, 95% CI [0.459, 1.122]. For EBP this percentage was 42.4%, ab = 0.287, 95% CI [0.189, 0. 404], and for functional impairment 70.0%, ab = 0.072, 95% CI [0.049, 0.121]. Indirect effects on impairment were strongest when perceived social support was low. Although we also present evidence that pathways between stressors and psychopathology may have been bidirectional, findings support the notion that adolescents' daily stressors are important transmitters of the impact of traumatic events and highlight the need for interventions focused not only on trauma processing but also on reducing current stress and improving social support.
