AbstractThe Family Intensive Treatment (FIT) team model provides intensive team-based, family-focused, comprehensive services to families in the child welfare system with parental substance misuse issues. The current evaluation study examined the effect of FIT on child safety, permanency, and parental wellbeing. A longitudinal quasi-experimental design with a two-group comparison using propensity score matching was used. Compared to a group of similar parents/caregivers receiving child welfare services (N = 2976), parents/caregivers who received FIT (N = 3025) were less likely to have new allegations of child maltreatment within 6 and 12 months after participating in the FIT program. There was no significant association between FIT receipt and recurrence of verified (i.e., substantiated) maltreatment: the rates of verified maltreatment were very similar for the parents/caregivers in the FIT group and the parents/caregivers in the comparison group. Similarly, no significant differences were found when the rates for foster care reentry were examined. In contrast, children of parents/caregivers who received FIT achieved permanency faster and at a greater rate compared to their counterparts. In addition, participation in the FIT program predicted improvement in parental/caregiver emotional protective capacity and overall protective capacity and showed a positive tendency in improvement of parental/caregiver behaviors related to their protective role. Finally, parents/caregivers who received FIT demonstrated significant improvements over time in several wellbeing domains including Daily Living Activities, Mental Health and Addiction, and Adult and Adolescent Parenting.
