A follow-up study of the “Lighthouse” mentalization-based parenting program: Mentalization as a mediator of change

This paper reports follow-up findings for an Mentalization based treatment (MBT) parenting intervention delivered to a community mental health sample. Parents completed the 12-week version of the Lighthouse Parenting Program (LPP) and were evaluated on parenting practices, parent-child relationships, parental mental health indicators, and child problem behaviour levels. We evaluated the extent to which improvements in mentalizing at follow-up mediated changes in parenting, parental adjustment, mental health, and child outcomes. Results included a reduction in parental coercive behaviours and child problems, improved parent-child relationship, and better parental psychological adjustment and mental health. Improvement in self-focused mentalizing were observed. Self-focused mentalizing mediated the changes in most outcomes from baseline to 3-month follow-up. These results provide strong preliminary evidence that the LPP improves parent and child outcomes.
