This meta-analysis examines the relationship between active coping and psychosocial health among youth. Results from 40 studies of coping with interpersonal stress were synthesized using a random-effects model. Four areas of psychosocial functioning were examined: externalizing and internalizing behavior problems, social competence, and academic performance. The magnitude of the relationship between active coping and psychosocial functioning was small, with correlations ranging from 0.02 for internalizing behavior to 0.12 for academic performance. Mean effects were moderated by stressor controllability: youth who used active coping in response to controllable stressors had fewer externalizing problems and higher social competence, as compared to those who used active coping in response to uncontrollable stressors. Implications for primary prevention programs and directions for future research on child and adolescent coping are discussed.
