Objective: Individuals who experience polyvictimization, or victimization across multiple life contexts, show particularly severe outcomes across a range of mental health diagnoses, potentially related to difficulties in regulating emotion. However, prior research has been limited by reliance on cross-sectional designs and retrospective trait measures of emotion regulation. The present study used ecological momentary assessment to test associations between polyvictimization and emotion regulation in daily life. Method: After completing a baseline survey assessing trauma exposure, mental health symptoms, and trait emotion regulation, undergraduates (N = 122) completed smartphone surveys assessing state emotion regulation four times per day for 14 days. Results: Low correspondence was observed between trait and state measures of emotion regulation. After accounting for baseline mental health symptoms, polyvictimization independently predicted lower scores on an aggregative measure of putatively adaptive strategies (i.e., reappraisal, acceptance, problem solving) in daily life. However, polyvictimization did not predict aggregate scores of putatively maladaptive strategies (i.e., cognitive and expressive suppression, rumination, impulsive behavior, avoidance). Baseline depression and posttraumatic stress predicted higher use of putatively maladaptive strategies. Conclusions: Results suggest polyvictimization may be associated with less use of adaptive emotion regulation in daily life, whereas mental health symptoms may be associated with more use of maladaptive strategies. These findings highlight the utility of experience sampling approaches for increasing insight into emotion regulation difficulties among trauma survivors.
