In-home based services developed as an alternative to out-of-home placement for at-risk children and adolescents. Since the late 1990s, there has been criticism of effective ways to measure in-home based programs. Most researchers agree on the effectiveness of in-home based services in reducing the number of youth placed outside the home, but there is little agreement on ways to measure the effectiveness of these services. The current study explored the benefits of in-home based services by examining whether overall functioning improved following treatment. The outcome measure for this study was Global Assessment Functioning (GAF). The study used pre-treatment and post-treatment GAF scores to evaluate responses to services for 209 clients, who ranged in age from 5 to 18. Based on the GAF scores, 91% of the clients demonstrated improvements, suggesting that youth that receive in-home based services might avoid out-of-home placement after treatment.
