Methods: This study used a longitudinal quasi-experimental design with propensity scores to examine the effects of recovery high schools. Participants were 260 adolescents with histories of SUDs who were enrolled in recovery high schools (n = 143) or high schools without a recovery focus (n = 117). Approximately 56% of the sample was male; with 83% White, 12% Hispanic, and 10% African American; and an average age of 16.28 years (SD = 1.09) at baseline. Dependent variables included measures of recent alcohol, marijuana, opiate, or other drug use. Three-level mixed-effects growth curve models (Rabe-Hesketh & Skrondal, 2008) were used to compare trajectories of substance use over the 12-month study period for students attending recovery high schools versus non-recovery high schools.
Results: Results from the multilevel growth curve models indicated that adolescents attending recovery high schools reported significantly greater reductions in alcohol use (b = -0.67, 95% CI [-1.22, -0.12], d = -0.33), marijuana use (b = -1.81, 95% CI [-2.79, -0.83], d = -0.64), and other drug use (b = -1.30, 95% CI [-2.03, -0.56], d = -0.47), relative to those in non-recovery high schools. There was no evidence that recovery high school attendance was associated with trajectories of opiate use (b = -0.17, 95% CI [-0.57, 0.23], OR = 0.84), however, opiate use was relatively rare in this sample of youth.
Conclusions: Recovery high school attendance may lead to significant reductions in substance use among youth with SUDs. Recovery high schools may thus offer a unique form of preventive continuing care for youth with SUDs by providing students with a safe and supportive learning environment.
