Abstract

This paper presents 2-year follow-up data for a sample of 159, 4- to 7-year-old children with oppositional-defiant disorder (ODD) who were randomly assigned to: parent training (PT), parent plus teacher training (PT + TT), child training (CT), child plus teacher training (CT + TT), parent plus child plus teacher training (PT + CT + TT). At the 2-year follow-up, approximately 75% of children were functioning in the normal range according to parent and teacher reports. Twenty-five percent of children were classified as treatment non-responders at home and/or at school. Teacher training added significantly to long-term school outcomes for children who had pervasive behavior problems. Baseline, post, and 1-year follow-up parenting practices distinguished between home treatment responders and non-responders (parents of non-responders were more critical and less positive). For children with baseline pervasive home-school problems, baseline maternal parenting and posttreatment marital discord were associated with poor treatment response at home at the 2-year follow-up. In addition, 80% of pervasive children whose mothers were highly critical immediately posttreatment were classified as school non-responders at the 2-year follow-up.
