This study examined the impact of the Family Check-Up (FCU) and linked intervention services on health-risk behaviors and social adaptation among youth in middle school.
A total of 593 students and their families were randomly assigned to receive either the intervention or the usual middle school services. Forty-two percent of intervention families engaged in the service and received the FCU. Using complier average causal effect analyses, engagement in the intervention moderated intervention outcomes. Youth in families that engaged in the intervention reported lower rates of antisocial behavior and substance use over time than did a matched control sample. Results extend previous research that indicates a family-centered approach to supporting youth in public school reduces antisocial behavior, alcohol use, tobacco use, and marijuana use during the middle school years.
