A randomized controlled trial of the triple P seminar series to promote parent and child self-regulation in Indonesia

This study evaluates the efficacy of the Triple P Seminar Series, a low-intensity, population-based parenting intervention in enhancing self-regulation among Indonesian parents and their children. A two-group randomized controlled trial (RCT) was conducted with 174 Indonesian parents of typically developing children aged 3–12. Self-regulation in parents and children, parenting practices, and child problematic behaviour were assessed at four-time points: baseline, post-intervention, three-month and six-month follow-up. Intent-to-treat was applied using linear mixed-model regression to evaluate intervention effects. Significant improvements in parent self-regulation and some domains of positive parenting practice over the 6 months were found. No significant differences were observed in child self-regulation and child misbehaviour across the conditions. Findings will contribute to the growing evidence on parenting interventions in non-WEIRD contexts and inform the potential of population-based parenting programs to promote self-regulation and positive parenting practices. This trial was pre-registered with the Australian New Zealand Clinical Trial Registry (ACTRN12623001009606). • An RCT tested Triple P seminars with Indonesian parents. • Parent self-regulation improved significantly over 6 months. • Parent - child relationship and parenting consistency increased. • No significant group differences in child self-regulation or misbehaviour. • Expands evidence on parenting programs in non-WEIRD settings.
