The mediating role of marital quality in parenting intervention: Effects on preschoolers' conduct problems and effortful control.

This study explores whether marital quality mediates the effects of a parenting intervention on preschoolers' conduct problems and effortful control. Using data from 209 children in a two-wave randomized controlled trial of the Hitkashrut program, participants were assigned to either a 14-session co-parent training group or a minimal intervention control group. Intent-to-treat analysis revealed that improvements in marital quality significantly mediated the intervention's impact on both conduct problems and effortful control. An alternative model, which hypothesized that changes in child behavior would lead to improvements in marital quality, was not supported, reinforcing the importance of targeting marital dynamics to achieve better child outcomes. These findings highlight the potential of marital-focused strategies within parenting interventions to foster healthier family environments and improve long-term developmental trajectories in children.
