About NREPP


What Is NREPP?

The National Registry of Evidence-based Programs and Practices (NREPP) is a searchable online database of mental health and substance abuse interventions. All interventions in the registry have met NREPP’s minimum requirements for review and have been independently assessed and rated for Quality of Research and Readiness for Dissemination.

The purpose of NREPP is to help the public learn more about available evidence-based programs and practices and determine which of these may best meet their needs. NREPP is one way that SAMHSA is working to improve access to information on evaluated interventions and reduce the lag time between the creation of scientific knowledge and its practical application in the field.

NREPP is a voluntary, self-nominating system in which intervention developers elect to participate. There will always be some interventions that are not submitted to NREPP, and not all that are submitted are reviewed. In addition, new intervention summaries are continually being added, so the registry is always growing. Please check back regularly to access the latest updates.

What Information Does NREPP Provide About Interventions?

NREPP publishes a report called an intervention summary on this Web site for every intervention it reviews. Each intervention summary includes:

  • General information about the intervention
  • A description of the research outcomes reviewed
  • Quality of Research and Readiness for Dissemination ratings
  • A list of studies and materials reviewed
  • Contact information to obtain more information about implementation or research

How Should NREPP Be Used?

NREPP can be a first step to promoting informed decisionmaking.

  • The information in NREPP intervention summaries is provided to help you begin to determine whether a particular intervention may meet your needs.
  • Direct conversations with intervention developers and others listed as contacts are advised before making any decisions regarding selection or implementation of an intervention.
  • A list of potential questions to ask developers (PDF, 54KB) is available from NREPP to facilitate these conversations.

NREPP rates the quality of the research supporting intervention outcomes and the quality and availability of training and implementation materials.

  • NREPP ratings do not reflect an intervention's effectiveness. Users should carefully read the Key Findings sections in the intervention summary to understand the research results for each outcome.

NREPP does not provide an exhaustive list of interventions or endorsements of specific interventions.

  • Use of NREPP as an exhaustive list of interventions is not appropriate, since NREPP has not reviewed all interventions.
  • Policymakers and funders in particular are discouraged from limiting contracted providers and/or potential grantees to selecting only among NREPP interventions.
  • Review of interventions and their posting on the NREPP Web site do not constitute an endorsement, promotion, or approval of these interventions by NREPP or SAMHSA.
