Examined influence of perceived self-efficacy for affect regulation with older adolescents. Found that self-efficacy to regulate affect related to high efficacy to manage academic development, resist social pressures for antisocial activities, and engage with empathy in others' emotional experiences. Perceived self-efficacy for affect regulation was mediated by behavioral forms of self-efficacy. Perceived empathic self-efficacy was accompanied by prosocial behavior, low delinquency, and increased vulnerability to depression in females. (Author/KB)
