•Perceived ethnic discrimination (PED) is associated with risky behaviors.•Theory suggests that this is particularly true for individuals with poor coping.•In a survey study, angry rumination interacted with PED to predict risky behaviors.•This interaction was not mediated by increased depressive or anxious symptoms.•Rumination may be an important process to target in ethnic minorities. Perceived ethnic discrimination (PED) is associated with increased engagement in risky behaviors in ethnic minority emerging adults. Risky behaviors may reflect efforts to cope with emotional distress like depression or anxiety resulting from PED, particularly for individuals with poor emotion regulation skills. We hypothesized that the association between PED and risky behaviors would be particularly strong for emerging adults with tendencies for angry rumination. We further hypothesized that increased depressive and anxious symptoms would mediate the effect of the PED-rumination interaction on risky behaviors. In this survey study, 155 ethnic minority college students completed measures of PED, depressive and anxiety symptoms, trait angry rumination, and risky behaviors. Analyses revealed that angry rumination moderated the association between PED and greater risky behaviors. Depressive and anxiety symptoms did not mediate this effect. Although cross-sectional, these findings suggest that individuals with poor coping skills may be especially likely to respond to stressors such as PED by engaging in risky behaviors. Implications include using rumination-focused interventions in order to prevent engagement in risky behaviors in ethnic minority emerging adults.
