Interpersonal skills training to reduce aggressive and delinquent behavior: limited evidence and the need for an evidence-based system of care.

The prevention of aggressive and delinquent behavior during childhood and adolescence is one of the highest priorities for public health and crime prevention. The most common approach to preventing or treating these conduct problems has been to provide interpersonal skills training to the affected youth. This paper reviews all randomized controlled trials evaluating interpersonal skills training programs as an intervention to reduce conduct problems. Research shows that such programs have weak empirical support as isolated interventions. An alternative evidence-based system of care is described. Such a system would include behavioral parent training and behavioral classroom-based interventions for young children at risk of developing problems, as well as multisystemic family therapy or multidimensional treatment foster care for chronic delinquents. Within such a network of services, interpersonal skills training could play an important supportive role. Such a system holds the greatest promise for reducing the prevalence of aggressive and delinquent behavior in communities.
