Study hypothesis

The diagnosis Conduct Disorder (CD) is used to refer to severely disruptive, aggressive and/or destructive behaviour characterised by a repetitive and persistent pattern of anti-social behaviour in children and adolescents with an estimated prevalence between 5% and 10%.

The hypotheses of this study are:
1. Parenting skills will improve and parental stress and depression will be reduced following parent training.
2. Children whose parents received parent training will show reduced problem behaviour and hyperactivity, and improved self-control.

Condition

Conduct disorder in pre-school children

Intervention

The study evaluates a parenting programme as an intervention. The 126 participants were randomly allocated to intervention and waiting list control on a 2:1 (intervention to control) basis, after they were stratified by age and sex of index child, using a random number generator. Block randomisation took place, that is, parents were randomly allocated to intervention or control after baseline assessment at each of the 11 areas. Families were seen at baseline, follow up one, two, and three, with each time point being six months apart.

The Webster-Stratton Incredible Years BASIC Parenting Programme was being delivered as the preventive intervention. The intervention was delivered between baseline and follow-up one, with controls being offered the intervention after follow-up one. Researchers collecting questionnaire and observational data at each time point were blind to which group/condition the participants were allocated to.
