The study examined several protective and vulnerability factors in a subsample of adolescents who witnessed high levels of interparental violence to determine what factors differentiated adolescents who inflicted (and received) violence in their dating relationship and those who had violence-free dating relationships. Males who witnessed high levels of interparental violence, who inflicted violence in their dating relationships, were differentiated from those who had violence-free relationships by the following variables: low socioeconomic status, exposure to community and school violence, acceptance of violence in dating relationships, and low self-esteem. Low socioeconomic status and acceptance of violence in dating relationships differentiated males who experienced dating violence and those who had not. With regard to females, exposure to community and school violence, poor school performance, and experiencing child abuse differentiated those who inflicted dating violence from those who had not, while poor school performance and experiencing child abuse differentiated females who experienced dating violence and those who had not.
