Path analysis was used to assess the contribution of 4 exogenous developmental variables (sexual abuse, physical abuse, exposure to violence, exposure to pornography - each occurring prior to age 13) and 4 personality constructs ("psychopathic and antagonistic attitudes," "psychosocial deficits," "pedophilia," "hostile masculinity") to the prediction of non-sexual delinquency and number of male child victims in a sample of 256 adolescent males with a history of "hands-on" sexual offending. "Psychosocial deficits" was found to partially mediate the effects of the exogenous variables on both outcomes. Exposure to violence both directly, and indirectly through "psychopathic and antagonistic attitudes," contributed to the prediction of non-sexual delinquency. Sexual abuse by a male directly, and indirectly through "hostile masculinity" and "pedophila," contributed to prediction of number of male child victims. Clinical implications of the findings are discussed. Tables, figure, and references (Published Abstract)
