Brief report: Ethnic identity and aggression in adolescence: a longitudinal perspective.

Ethnic identity has been found to relate to many positive psychological outcomes, such as self-esteem and well-being, but little has been said about negative social outcomes such as aggression, nor have these relations been tested across time. The current study examined the concurrent and longitudinal relations between ethnic identity and peer nominated aggression at two time points with a two-year interval (8th and 10th grades) in a sample of 125 Israeli adolescents with an immigration background (56.8% girls). As hypothesized, ethnic identity related negatively to aggression at both T1 and T2. In addition, ethnic identity predicted a relative decrease in future aggression. Given these findings, the article suggests the importance of strengthening ethnic identity through interventions and educational programs.
