ABSTRACT: Unhealthy family dynamics often develop in families where addiction is present and negatively impact individual and family health. Family members becoming ready to make personal changes might positively impact family functioning and improve family support. More research is needed to examine this relationship in family recovery. Using structural equation modeling, family member readiness to change and family functioning over time were examined. Readiness and family functioning were positively and reciprocally associated with each other across 2 assessment points. Gender was associated with initial readiness to change and family functioning. Individual readiness to change may enhance family functioning and promote recovery-oriented changes for each family member.
