The effect of assertive continuing care on continuing care linkage, adherence and abstinence following residential treatment for adolescents with substance use disorders

Aims This study compared assertive continuing care (ACC) to usual continuing care (UCC) on linkage, retention and a measure of continuing care adherence. Outcome analyses tested the direct and indirect effects of both conditions and level of adherence on early (months 1–3) and longer-term (months 4–9) abstinence. Design Two-group randomized design. Setting Eleven counties surrounding a community-based residential treatment program in the Midwestern section of the United States. Participants A total of 183 adolescents, ages 12–17 years, with one or more Diagnostic and Statistical Manual version IV (DSM-IV) substance use dependence disorder and met American Society for Addiction Medicine (ASAM) placement criteria for non-medical residential treatment. Intervention Prior to discharge from residential treatment, participants were assigned randomly to receive either UCC, available at outpatient clinics in the 11-county study area, or ACC via home visits. Measurements Self-reported interview data were collected at intake, 3, 6 and 9 months post-residential discharge. Urine test data and interviews with a caregiver were conducted at baseline and 3 months. Findings ACC led to significantly greater continuing care linkage and retention and longer-term abstinence from marijuana. ACC resulted in significantly better adherence to continuing care criteria which, in turn, predicted superior early abstinence. Superior early abstinence outcomes for both conditions predicted longer-term abstinence. Conclusions ACC appears to be an effective alternative to UCC for linking, retaining and increasing adherence to continuing care. Replication with larger samples is needed to investigate further the direct and indirect effects of ACC found in this study.
