Parental reflective functioning (PRF) is the ability of parents to understand their child’s behavior in light of underlying mental processes; it is a core element in the parent–child relationship. RF is also considered crucial for self-regulation for both parents and their children. We investigated the relationship between improvement in PRF after DUET group intervention (a RF-based intervention) and improvement in the parent–child interaction, child RF, and child adjustment, and we examined whether these improvements were distinct for children with different temperamental traits (e.g., effortful control). Eighty-four parents completed the DUET program and were assessed before and after the intervention. PRF was measured using observation (mind-mindedness) and a questionnaire. Statistical analysis included hierarchical regression and moderation of regression analysis. Results showed that improvement in the parent–child interaction, child RF, and child behavioral problems were related to improvement in PRF. Furthermore, we found that child temperament acted as a moderator in the link between PRF and child RF, supporting a vantage sensitivity model, meaning that it was the more sensitive children who benefitted the most as a result of the positive change in their parents’ RF. Clinical and future directions of this study are discussed.
