This article reviews the state of the science on psychosocial treatments for disruptive behaviors in children, as an update to Eyberg, Nelson, and Boggs (2008). We followed procedures for literature searching, study inclusion, and treatment classification as laid out in Southam-Gerow and Prinstein (2014), focusing on treatments for children 12 years of age and younger. Two treatments (group parent behavior therapy, and individual parent behavior therapy with child participation) had sufficient empirical support to be classified as well-established treatments. Thirteen other treatments were classified as probably efficacious. Substantial variability in effectiveness of different programs within the same treatment family has been previously documented; thus, a particular level of evidence might not hold true for every individual program in a treatment family. Systematic investigations of implementation, dissemination, and uptake are needed to ensure that children and families have access to effective treatments. Investigations into how to blend the strengths of the effective approaches into even more effective treatment might also lead to greater impact.
