Results revealed that the experiences of childhood sexual abuse and parental alcoholism independently predicted higher levels of suicidality. In addition, participants' reports of past family conflict were associated with higher levels of suicidality, whereas reports that families were cohesive, fostered expressiveness and independence, engaged in intellectual-cultural recreational opportunities, and emphasized moral and religious values were associated with decreased risk. Regression models were useful in describing the joint effects of childhood adversity and family environment. Findings suggested that childhood sexual abuse and parental alcoholism increase suicidality and that specific interventions that could be studied for effectiveness include the reduction of family conflict and efforts aimed at increasing the level of family cohesion.
