| Scientific title | Treatment of oppositional defiant and conduct problems in young Norwegian children: results of a randomised controlled replication trial |
| Study objectives | The aims of the present study were to compare the effects of the Incredible Years (IY) basic parent training (PT) program, or PT combined with child therapy (PT+CT) to a waiting list control (WLC) condition in a randomised controlled trial including a one-year follow-up. |
| Ethics approval(s) | Informed consent was obtained from all parents. The study was approved by The Regional Committee for Ethics in Medical Research, University of Tromsø, and by the Norwegian Data Inspectorate in January 2001. |
| Health condition(s) or problem(s) studied | Oppositional defiant disorder and/or conduct disorder |
| Intervention | The treatment program, IY, was developed by Professor Carolyn Webster-Stratton at the parenting clinic at the University of Washington. IY is a manualised and video-based training program for young children with conduct problems. In child training (CT), groups of six children met with two therapists in the clinic for 18 - 20 weekly two-hour sessions, in all 36 - 40 hours of treatment in the Incredible Years Dinosaur School Program. The parents to children in CT participated in PT parallel to the CT intervention. The parents assigned to the PT condition were divided into groups of 10 - 12 parents (i.e. the parents of about six children in each group), who met weekly for 12 - 14 weeks for two hours with two accredited therapists. During the sessions, parents watched 250 video vignettes showing parent-child interactions. The therapists led discussions of central aspects of parenting on the basis of the video vignettes. The aims of the parent program are to promote parent competences and strengthen families by increasing parents' positive parenting, self-confidence in parenting, reduce negative parenting, improve parents' problem-solving skills and anger management, and improve school involvement. Parents receive home tasks and each session started with the parents describing their experience of these exercises. Children/families in the waiting list condition (WLC) were offered treatment after six months of waiting, for ethical reasons and these children were unavailable at the one-year follow-up. The children/families underwent a three-hour assessment before and after the waiting period. One year after ended treatment, a one-year follow-up assessment (12 months after terminated treatment) was conducted. |
| Intervention type | Other |
| Primary outcome measure | 1. Eyberg Child Behaviour Inventory (ECBI) 2. Kiddie-Schedule for Affective Disorders and Schizophrenia (Kiddie-SADS) Assessments in the active treatment were conducted before treatment and at the end of the treatment interventions (approximately 21 - 24 weeks after the initiation of the intervention), and 12 months after the post-assessments the one-year follow-up was conducted. The WLC was not available at the one-year follow-up. |
| Secondary outcome measures | 1. Child Behaviour Checklist (CBCL) 2. Teacher Report Form (TFR) 3. Parental Stress Index (PSI) Assessments in the active treatment were conducted before treatment and at the end of the treatment interventions (approximately 21 - 24 weeks after the initiation of the intervention), and 12 months after the post-assessments the one-year follow-up was conducted. The WLC was not available at the one-year follow-up. |
