The aim of this study was to conduct an experimental outcomes evaluation to examine the impact of adding an evidence-based family strengthening program to reentry services for fathers leaving jail or prison. The program, Strengthening Families Program for Parents and Youth 10-14 (SFP), was tested to see whether it improved family functioning and child well-being among a vulnerable population of reentering fathers with children ages 10-14. Eighty families were randomly assigned to a control group or to the SFP group. Differences in key father, child, and caregiver outcomes were assessed. An implementation evaluation was also conducted to provide clarification and understanding of the outcome evaluation results, and an opportunity to replicate and extend practices that work best with reentering fathers.
