In this study, we explore how specific individual, family, and family-within-community characteristics, as well as aspects of in-home family therapy, relate to responses to treatment. The Child and Adolescent Functional Assessment Scale scores and Global Assessment of Functioning scores were used as outcome measures. Results revealed significant differences between pre- and post-scores for clients receiving in-home family therapy services, providing an initial indicator of treatment success. In addition, primary family caregiver social support, role performance in school/work, and self-harmful behavior were indicative of successful outcomes. Clients with higher problem levels had the greatest rates of change, and clients receiving more hours of services fared better in therapy.
