This article presents the results of a study pertaining to the adolescent perception of the support he/she receives from his/her friends and its mediator effect in the relationship between domestic violence and behavior. The data were collected by questionnaire administered to 490 youths. The results show that domestic violence negatively impacts the girls’ behavior. However, for the boys, domestic violence only predicts the presence of the externalizing behavior. For the girls only, the relationship between domestic violence and behavior can be partially explained by the perception of support from friends.
