This chapter offers a review of the behavioral model of psychosocial treatment for early-onset conduct problems (CPs). It focuses on three common formats of psychosocial treatment for them: individual family-based treatment, group-based treatment, and school-based treatment. The chapter then highlights a number of promising trends in, and future directions for, the psychosocial treatment of early childhood CPs, including technology-based treatments to expand the scope and reach of care and intensive treatment formats. The chapter also reviews some of the most widely researched and utilized psychosocial intervention protocols for the treatment of early child CPs. The intervention programs for young children with CPs best supported by the outcomes of clinical trials are behavioral in nature, and incorporate social learning theory and coercion theory. The chapter concludes by discussing areas in need of further empirical attention in order to optimize psychosocial procedures for redressing CPs that present in early childhood.
