Scaling Prevention Training: Evaluating the Outcomes of a Digital Prevention Specialist Course in a Statewide Block Grant Context

This study evaluated the effectiveness of an asynchronous Certified Prevention Specialist (CPS) training course in improving prevention knowledge and credential readiness among applicants and providers engaged in Indiana's Substance Use Prevention, Treatment, and Recovery Block Grant. Twenty-five community health professionals completed the self-paced online course, which was aligned with International Credentialing and Reciprocity Consortium standards and state training requirements. Data were collected from January 5 through October 1, 2024. Using a pre/post-test design with linear regression, participant outcomes were assessed through knowledge gains, module-level assessments, and CPS exam performance. Results indicated significant improvements in knowledge, with mean test scores rising from 38.84 (SD = 4.99) at baseline to 48.68 (SD = 5.48) post-course (t = 7.85, p < .001), or an 18 percentage point average increase. Regression analysis showed that younger participants, those with less formal education, and those without prior prevention training benefited most from the intervention. Module-level assessments averaged 92%, and among those who attempted the CPS exam (n = 5), 80% achieved a passing score. These findings demonstrate the effectiveness of asynchronous digital training for advancing prevention workforce development, particularly among early-career and less experienced providers. As a scalable, cost-free, and credential-aligned training model, this approach offers state agencies a viable strategy to expand workforce capacity and standardize prevention competencies. Broader adoption could strengthen prevention infrastructure nationwide by improving access to high-quality, flexible training that prepares professionals to implement evidence-based prevention strategies effectively.
