Brief Summary

Aim of study: To evaluate the effects of the shortened version of the Incredible Years (IY) Basic programme, the study which the parents were recruited to. A randomising experimental control between-group design was used with pre- and post-intervention measurements, and a one-year, four-year and ten-year follow-up. Children and families were randomized to either the shortened basic version (n = 89), or the control group (n = 97).

Outcome Measures

Primary Outcomes (1)

  • Longitudinal change in ECBI scores

    Eyberg Child Behavior Inventory (Robinson et al., 1980). The ECBI provides a list of 36 problem behaviours commonly reported by parents of children with disruptive behaviour problems. The inventory assesses behaviour on two dimensions: the frequency of the behaviour and its identification as a problem. The frequency ratings range from 1 (never) to 7 (always), and are summed to yield an overall problem behaviour Intensity score (Cronbach's alpha 1⁄4 0.82) ranging from 36 to 252.

    baseline, 6-8 weeks after intervention, one-year follow up, four-year follow up, ten-year follow up

Secondary Outcomes (4)

  • Reasons for participation and help seeking behaviour

    Four-year follow up

  • Longitudinal change in PROC scores

    baseline, 6-8 weeks after intervention, one-year follow up, four-year follow up, ten-year follow up

  • Longitudinal change in PSI scores

    baseline, 6-8 weeks after intervention, one-year follow up, four-year follow up, ten-year follow up

  • Longitudinal change in PPI scores

    baseline, 6-8 weeks after intervention, one-year follow up, four-year follow up, ten-year follow up

Brief Incredible Years parent trainingBEHAVIORAL

The IY parent training programme (3-8 years) developed by Webster-Stratton at the Parenting Clinic, University of Washington, is a manualised and video-based training programme for parents of young children with conduct problems (Webster-Stratton and Reid, 2003a). Parents assigned to the short IY Basic (S-IY) condition were divided into groups of 10-12 parents. The S-IY was led by two experienced group leaders and parents met weekly for two-hour sessions at a public health care center in the community. The group leaders led discussions regarding central aspects of parenting on the basis of the video vignettes, role play and homework.
