Family-management skills of parents of seventh- and tenth-grade boys were related to each of 2 criterion measures of delinquency: police contacts and self-reported delinquency. The measures of family-management skills were monitoring, discipline, problem solving, and reinforcement. The measures of parent monitoring and discipline were shown to correlate significantly with both criterion measures. The monitoring score accounted for the most variance in both criterion measures of delinquency, and the problem solving and reinforcement measures accounted for the least. The monitoring score also differentiated moderate offenders from persistent offenders.
