The problem
Intervention: Solution-focused brief therapy (SFBT), a strengths-based therapeutic approach delivered to parents in the child welfare system
Who it was tested with: 180 parents involved in the child welfare system with substance use disorders attending an outpatient addiction treatment center.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"A randomized controlled trial design was used to evaluate the effectiveness of SFBT as compared to treatment-as-usual in an outpatient substance abuse treatment center. Mixed linear models tested within and between-group changes using intent-to-treat analysis (N = 180)." This represents a rigorous experimental design with randomization and comparison group, meeting standards for causal inference, though the null between-group findings limit conclusions about SFBT's unique effectiveness.
The lack of statistically significant differences between groups means SFBT cannot be shown to outperform standard care. The study does not establish whether improvements were due to SFBT specifically or to non-specific factors like treatment engagement.
