Anger feelings and anger expression as a mediator of the effects of witnessing family violence on anxiety and depression in Japanese adolescents

The effects of anger feelings (rated by the State-Trait Anger Expression Inventory) and witnessing family violence on anxiety and depression (rated by the Hospital Anxiety and Depression Scale) were examined in 457 junior high school students. Anxiety and depression scores were correlated with frequencies of witnessing family violence. In a regression analysis, however, after controlling for the demographic variables and depression score, the anxiety score was predicted by State Anger, Anger-Out, and Anger-Control; the depression score was predicted, after controlling for the demographic and anxiety score, by State Anger, Anger-In positively, and by Anger-Out and Anger-Control negatively. Witnessing family violence failed to add significant contribution in predicting anxiety or depression. These results were generally supported by structural equation modeling. The effects of witnessing family violence on dysphoric mood may be mediated by anger feelings. The style of dysphoric mood may be predicted by the style of anger expression.
