 Participants in this 18-month, open-label study will be randomly assigned to either receive standard of care or participate in an MFG in addition to receiving standard of care. Participants assigned to standard of care will receive treatment that is traditionally offered to outpatients. Participants in an MFG will meet in their groups once a week for 16 weeks. Sessions will include adult caregivers and all children over age 6. Each session will follow the same procedures, and will proceed through the following stages: creating social networks; information exchange; group discussions; individual family practice; and homework assignment. Assessments of youth functioning will be held at Weeks 8 and 16 and Months 6 and 18 post-treatment.
