This study sought to identify lessons for social workers from the health care research on influencing practitioners to use evidence-based practices (EBP). Research reviews of strategies to influence providers to use EBP are summarized. Among the findings are that printed educational materials, the use of local opinion leaders, and continuous quality improvement are weak interventions. Educational outreach visits and audit and feedback showed weak to moderate effects, whereas certain types of continuing education and use of computers showed moderate effects. Although much needs to be learned about providing social workers with the latest research knowledge, a combination of strategies is more likely to be effective. (Contains 1 table.)
