Strategies to increase readiness to change may enhance community-based substance use treatment outcomes. This study evaluated the effect of solution-focused brief therapy (SFBT) on readiness to change and substance use compared to treatment as usual (TAU) in a Brazilian community-based substance use treatment center.One hundred two adults (M = 36.79, SD = 10.29) were quasi-randomized into SFBT or TAU groups. Assessments were completed at baseline, post-test, and 1-month follow-up. The primary outcome was the changes in readiness to change at post-test and 1-month follow-up. The secondary outcome was the change in substance use at 1-month follow-up.Through Quade non-parametric analysis of covariance (ANCOVA), both groups decreased tobacco, alcohol, and cocaine/crack use at 1-month follow-up, but SFBT had greater reductions in alcohol use (p = .05). ANCOVA analysis demonstrated no differences between groups on readiness to change at any time point. However, among participants who used multiple substances (n = 59), SFBT showed higher readiness to change at post-test (p = .05).These findings strengthen the evidence that SFBT holds promise for positive community-based substance use treatment outcomes.
