Differences between child welfare- and nonchild welfare-involved families regarding barriers to child mental health care, attendance, program satisfaction, and relationship with facilitators are examined for a multiple family group service delivery model aimed at reducing childhood disruptive behaviors. Although child welfare-involved caregivers reported more treatment barriers and less program satisfaction than non-child-welfare-involved families, no significant differences exist between groups on average total sessions attended and attendance rates over time.
