This study examined the predictive validity of the Washington Circle (WC) continuity of care after long-term residential treatment performance measure, as well as the impact of assertive continuing care interventions on achieving continuity of care. This measure is a process measure that focuses on timely delivery of a minimal floor of services that are necessary to provide sufficient quality of treatment but should not be construed to be the optimal continuity of care after residential treatment for any specific adolescent. Participants included 342 adolescents who were admitted to long-term residential treatment and randomly assigned to either standard continuing care or an assertive continuing care condition. Overall, results provide initial support for the WC continuity of care after residential treatment performance measure as a useful predictor of 3-month recovery status. In addition, assignment to an assertive continuing care condition was found to significantly increase the likelihood of achieving continuity of care. (C) 2010 Elsevier Inc. All rights reserved.
