Abstract
Background and objectives: Stress is well established as a strong risk factor for internalizing psychopathology. Learned helplessness research demonstrates that perceived controllability of stressors affects internalizing symptoms. Furthermore, subjective perceived stress is associated with psychopathology. However, most recent research has focused on measuring the frequency and expert-rated severity of stressful life events despite evidence for the importance of stress perceptions. The present study brings together past and current literatures to investigate the importance of perceived severity and controllability of recent life events in the association between stressors and internalizing symptoms.
Design and methods: We used a revised version of the Adolescent Life Events Questionnaire (ALEQ) that asked participants (ages 13-22, N = 328) to rate the frequency of 65 stressful events typical to youth, as well as the perceived stressfulness and control they felt over each event. Events were categorized prior to analysis as dependent (self-generated), independent (fateful) or neither.
Results: Controllability and severity appraisals were associated with depression and anxiety symptoms, controlling for stressor frequency (which also predicted symptoms), for dependent but not independent stressors.
Conclusions: These results highlight the importance of controllability and severity appraisals as potential risk factors for internalizing disorders, exposing a potential target for therapy.
