Little is known about what additional services youth receive while they reside in out-of-home treatment settings. However, such information may be crucial for explaining effectiveness and variation in outcomes for youth in such settings. Our research examines patterns of multi-sector service use for youth in two settings--Therapeutic Foster Care and group homes. Data come from in-person interviews with Treatment Foster Parents and Group Home Staff for a NC state-wide sample of youth with psychiatric disorders and aggressive behavior. Findings indicated high rates of service use by youth in both settings. Analyses indicated significant differences in service types used by youth in each setting, yet similar volume of service use between settings. Clinical and demographic factors did not significantly influence types of services received. Differences in service patterns between the two groups indicated that youth in TFC were more likely to receive community-based, individualized services while youth in group homes were more likely to receive more restrictive services.
