The aim of this study was to examine the relative effectiveness of Collaborative and Proactive Solutions (CPS) and Parent Management Training (PMT) for youth with oppositional defiant disorder (ODD) in a community setting. Based on a semi-structured diagnostic interview, 160 youth with ODD (age 7-14; 72% male; ethnicity representative of the wider Australian population) were randomized to CPS (n = 81) or PMT (n = 79) for up to 16 weekly sessions. The primary hypothesis was that participants in the CPS group, treated in a community setting, would exhibit significant improvement in ODD, equivalent to that of an evidence-based treatment, PMT.Assessment was conducted at baseline, post-intervention, and at 6-month follow-up, using independently-rated semi-structured diagnostic interviews, parent-ratings of ODD symptoms, and global ratings of severity and improvement. Analyses were conducted with hierarchical growth linear modeling, ANCOVA, and equivalence testing using an intent-to-treat sample. Both treatments demonstrated similar outcomes, with 45-50% of youth in the non-clinical range after treatment, and 67% considered much improved. No differences were found between groups, and group equivalency was shown on the independent clinician and parent-rated measures. Gains were maintained at the 6-months follow-up. In conclusion, CPS works as effectively as the well-established treatment, PMT, for youth with ODD, when implemented in a community-based setting. As such, CPS provides a viable choice for families who seek alternate treatments.
