Treatment Outcomes and Mediators of Parent Management Training: A One-Year Follow-Up of Children with Conduct Problems

This effectiveness study presents the results of a 1-year follow-up of a randomized controlled trial of Parent Management Training. Families of 112 Norwegian girls and boys with clinic-level conduct problems participated, and 75 (67%) families were retained at follow-up. Children ranged in age from 4 to 12 at intake (M=8.44). Families randomized to the control group received an active treatment alternative as would be normally offered by participating agencies. Multi-informant, multisetting outcome measures were collected and results from both intention-to-treat and treatment-on-the-treated analyses are presented. In two separate indirect effects models, assignment to Parent Management Trainingthe Oregon model predicted greater effective discipline and family cohesion at postassessment, which in turn predicted improvements in several child domains at follow-up.
