Investigating Active Ingredients of the GenerationPMTO Intervention: Predictors of Postintervention Change Trajectories in Parenting Practices

Empirically determining the active ingredients of evidence-based parenting interventions is a promising means for strengthening interventions and enhancing their public health impact. This study aimed to determine which distinct ingredients of the GenerationPMTO (GenPMTO) intervention were associated with subsequent changes in parenting practices. Using a sample of 153 participants randomly assigned to the GenPMTO condition, we employed multilevel modeling to identify intervention ingredients empirically linked with change trajectories in parenting practices observed across the 2 years following intervention exposure. Coercive parenting and positive parenting outcomes were examined. Study results indicated that emotion regulation, effective communication, problem solving, and monitoring each demonstrated a significant pattern of findings for coercive parenting. Differential exposure to each of these ingredients significantly predicted the level of coercive parenting immediately postintervention and/or trajectories of change in coercive parenting across the subsequent 2-year period, controlling for coercive parenting at baseline. No significant predictors were found for positive parenting trajectories. Our findings suggest four components as active ingredients of the GenPMTO intervention for coercive parenting. Identification of these active ingredients may lead to strengthening future iterations of GenPMTO by expanding the set of core components specified in the model, which may further improve public health benefits. Implications for further understanding change stemming from evidence-based parenting interventions are also discussed.
