The review of new evidence 5 years later: SAMHSA's National Registry of Evidence-based Programs and Practices (NREPP)

The Substance Abuse and Mental Health Services Administration (SAMHSA) decided that NREPP should offer a second review option for interventions that have already been reviewed and included in the registry for 5 years. Principals from 135 such interventions were invited to participate in a second review, and an exploratory study of the Principals' responses to this invitation was conducted. The study used a mixed-method approach, quantitatively describing characteristics of Principals and their interventions and qualitatively summarizing feedback from phone interviews with a convenience sample of Principals participating in a second review. Of the Principals invited, 21% accepted a second review, 24% were interested but unable or not ready to submit materials, and 56% did not accept or did not respond. Mental health treatment interventions were more likely to undergo a second review, and substance abuse treatment interventions were less likely. Similar percentages of interventions undergoing a second review had received funding from the National Institutes of Health (86%) and had been evaluated in a comparative effectiveness research study (79%). Overall ratings for interventions improved in each second review completed. The interviewed Principals perceived potentially lower ratings as the only risk in participating in a second review.
