Adolescent community reinforcement approach in secure care for adolescents with substance use and serious norm-violating behaviour: a randomised feasibility trial.

Abstract

Adolescents placed in state-run secure youth homes (by the Swedish National Board of Institutional Care) due to substance misuse and serious norm-violating behaviour (including offending) are in pressing need of effective help, yet available treatments lack scientific support. The treatment Adolescent Community Reinforcement Approach (A-CRA) supports abstinence and improves social functioning in outpatient settings, but has not been evaluated in secure youth homes. To evaluate the feasibility, acceptability and preliminary effects of A-CRA in Swedish secure youth homes, and assess the feasibility of study procedures before a multicentre randomised controlled trial (RCT). In a randomised feasibility trial, 42 adolescents (16-20 years) at four secure youth homes were allocated to A-CRA plus treatment as usual (A-CRA+TAU; n=22) or TAU alone (n=20). Substance use was measured with self-reports and registry data at baseline, post-treatment and up to 24 months after treatment; participants were also interviewed about acceptability and satisfaction. Feasibility was demonstrated: 77% reached the predefined exposure threshold (≥12 A-CRA procedures). Adolescents found the intervention acceptable and helpful in secure care. Study procedures were largely workable, though questionnaire data showed substantial missingness. Preliminary effects were favourable, with no evidence of harm. A-CRA appears feasible in secure youth care, with minor adjustments, and is perceived as helpful and acceptable by adolescents. Treatment effects will be evaluated in an upcoming multicentre RCT.
