The purpose of the current study was to examine the relationships among selected family interaction variables and psychosocial outcomes in a sample of Jamaican adolescents. The authors hypothesized that adolescent psychosocial outcomes would be negatively associated with physical violence, verbal aggression would be more potent than physical violence, and the combined effect of all aggression and violence would be more detrimental than either form of aggression by itself. Overall, the results supported the authors' hypotheses about the detrimental effects of negative family interactions on children's well-being. All the parent-child and interadult variables were positively associated with problematic adolescents' adjustment. However, the verbal aggression variables indicated a greater adverse effect than the physical violence variables. Additionally, the combined effect of parent-child and interadult aggression and violence indicated greater detriment to adjustment than each factor by itself. Interpretation of the findings within the Jamaican context and direction for future research are discussed. (Contains 4 tables.)
