ABSTRACT
During the past decade, youth violence has received increasing attention as a major public health issue in Puerto Rico as well as in the United States. This study sought to identify risk and protective factors of youth violence in a representative sample of school adolescents in Puerto Rico. Risk and protective factors were grouped into five domains: individual, family, peer group, school and community. From a total of 2,385 participants, 10.7 reported at least one violent behavior and 3.4 reported two or more violent behaviors. In multiple regression analysis the risk factors identified were male gender, junior grade students, having a favorable attitude towards antisocial behavior, use of ecstasy, involvement with antisocial peers and reporting antisocial parents. Participation in family decisions was the only protective factor associated with violence. Findings from this study could have important implications for the development of preventive programs for the adolescent population in Puerto Rico
