Launched in March 2007, the Substance Abuse and Mental Health Services Administration (SAMHSA) established the National Registry for Evidence-based Programs and Practices (NREPP), an online searchable database of mental health and substance use interventions. Inclusion on the list of interventions does not mean endorsement as the interventions are self-nominated and voluntary. Ratings range from the lowest of 0.0 to the highest of 4.0.  In July 2013, NREPP posted its 300th intervention summary.

The emphasis of the California Evidence-Based Clearinghouse for Child Welfare (CEBC) is on child welfare programs and practices.  It, too, offers an online searchable database.  Interventions are rated on a five-point rating scale where 1=strongest research evidence to 5= concerning practice that appears to pose substantial risk to children and families.  The intervention’s relevance to child welfare is also provided.

The US Office of Juvenile Justice and Delinquency Prevention offers an online searchable guide to model prevention and intervention programs.  Programs are reviewed on the basis of effectiveness and deemed exemplary, effective, or promising and included in the Model Program Guide.

Blueprints for Healthy Youth Development limit their program reviews to practices that prevent problem behaviors and facilitate healthy development.  Reviewers examine effectiveness to determine whether a problem is model or promising; model programs and their effectiveness designation are included in an online, searchable database.
