This article presents new information on the reliability of the North Carolina Family Assessment Scale (NCFAS), the measurement of family functioning, and the concurrent and predictive validity (Rubio, Berg-Weger, Tebb, Lee, & Rauch, 2003) of the NCFAS in relation to placement prevention and future placement among families receiving Intensive Family Preservation Services (IFPS). The NCFAS shows growing promise as a practice-based instrument that assists practitioners in the identification of treatment needs of families referred for service, detecting and assessing treatment-related changes that occur in the NCFAS’s measured domains, relating those changes to the placement status of children at the end of service, and in predicting the likelihood of the children’s future out-of-home placement.
