Abstract
This short-term longitudinal study examined psycho-social influences on substance use and mental health among children of divorced parents. The sample consisted of ethnically diverse fifth and sixth grade students, and compared children of divorced parents (CODPs; N = 176), who were an average of four years post-divorce, with children of married parents (COMPs; N = 213) who had never divorced. CODPs reported more life stress, less problem-focused coping, and more substance-using friends and family members than COMPs. Further, these variables were significantly related to CODPs' greater reported substance use, aggressive behavior, and depression than COMPs cross-sectionally, and longitudinally, four months later. The results suggest the importance of including both substance use and mental health outcomes in preventive interventions for CODPs.
