Trial of a Parenting Discussion Group in Panama, Central America

This is a randomized controlled trial (RCT) with two groups (waiting list versus Triple P discussion groups) and measurements at pre-intervention, post intervention, three and six months follow up.

The intervention trialed was a 2-hour, one-session discussion group on child noncompliance. Groups were composed by a maximum of 10 parents and were facilitated by the principal researcher, who is an accredited practitioner. The groups were interactive and discussion based, and a power point presentation with embedded-video clips were used to aid the facilitator. The key points that were covered in the discussion group included reasons for disobedience, parenting traps, encouraging good behaviour, and managing disobedience. Parents also received a workbook that included the content covered in the discussion group and 2 follow up telephone calls to check how they were doing after.

Participants were randomly assigned to a treatment group (Triple P discussion groups) or to a waiting list group. A statistician independent from the research team generated a random list of numbers. Randomization was stratified based on the level of child behavioural difficulties (high or low) measured at baseline. In order to ensure allocation concealment, sequentially-numbered, opaque, sealed envelopes (SNOSE) were opened after participants agreed to take part in the study and completed a baseline assessment. After randomization, those assigned to the waiting list group were assessed at time 1 (baseline) and then 4 weeks, 3 months and 6 months after the first assessment. Those assigned to the treatment group were assessed at time 1 (baseline), 2 weeks, 3 months and 6 months after the intervention. Assessments were carried out by a research assistant who was blind to group allocation.
