 This is a multi-county randomized controlled trial of the Fostering Healthy Futures FHF preventive intervention program consisting of mentoring and skills groups with 256 maltreated preadolescent youth in out-of-home care. It is hypothesized that participation in the FHF program will result in better functioning in cognitive, social, and behavioral domains, and that these gains will result in improved mental health functioning, quality of life, and reductions in problem behaviors and adverse life-course outcomes.
