In this study, we examined the functioning of children and families treated in an intensive family preservation service program. Study subjects were 42 adolescent children and one of their parents. Subjects were studied at admission, at discharge, and between 9 and 12 months after discharge. Data were drawn from interviews with children, their parents, and their caseworkers. Interviews were semistructured and included four standardized measures. Univariate and multivariate analyses revealed that at follow-up children and their families were functioning at a lower level than nonclinical samples, their functioning improved between admission and discharge and did not decline between discharge and follow-up, and child and family factors were more strongly associated with family functioning at follow-up than were treatment factors.
