Parenting intervention effects on reunification: A randomized trial of PMTO in foster care.

Evidence-supported parenting interventions (ESPIs) have expanded into child welfare because a growing research base has demonstrated positive results among children with serious emotional and behavioral problems. Despite a clear federal policy emphasis on reunification, few randomized trials have tested ESPIs with biological families of children in foster care; even fewer studies have investigated the distal outcomes of ESPIs. The aim of the current study was to examine the effects of Parent Management Training, Oregon (PMTO) model on reunification. Children in foster care with emotional and behavioral problems were randomized to in-home PMTO (n = 461) or services as usual (SAU) (n = 457). Cox regression models tested whether children in the PMTO group achieved higher rates of reunification. We applied life tables data for integrals calculations to estimate days saved in foster care. Analyses were conducted as intent-to-treat (ITT), and per protocol analysis (PPA). ITT results showed reunification rates were 6.9% higher for the PMTO group (62.7%) than the SAU group (55.8%) with 151 days saved per typical child. PPA indicated that intervention completion strengthened effects as PMTO completers' reunification rates (69.5%) were 13.7% higher than the SAU group (55.8%), and were 15.3% higher than non-completers (54.2%). Days saved were also greater for completers as compared to the SAU group (299 days) and non-completers (358 days). Overall, findings suggest that an in-home parenting intervention positively affected reunification as delivered to biological parents of children and youth in foster care with serious emotional and behavioral problems. Implications and future considerations for research are discussed.
