References to Evidence-based Program Registry (EBPR) websites for behavioral health in U.S. state government statutes and regulations.

Background and aim: U.S. state governments have the responsibility to regulate and license behavioral healthcare interventions, such as for addiction and mental illness, with increasing emphasis on implementing evidence-based programs (EBPs). A serious obstacle to this is lack of clarity or agreement about what constitutes "evidence-based." The study's purpose was to determine the extent to which and in what contexts web-based Evidence-based Program Registries (EBPRs) are referenced in state government statutes and regulations ("mandates") concerning behavioral healthcare. Examples are: What Works Clearinghouse; National Register of Evidence-based Programs and Practices; Cochrane Database of Systematic Reviews. Methods: The study employed the Westlaw Legal Research Database to search for 30 known EBPR websites relevant to behavioral healthcare within the statutes and regulations of all 50 states. Results: There was low prevalence of EBPR references in state statutes and regulations pertaining to behavioral healthcare; 20 states had a total of 33 mandates that referenced an EBPR. These mandates usually do not rely on an EBPR as the sole acceptable source for classifying a program or practice as "evidence-based." Instead, EBPRs were named in conjunction with internal state or external sources of information about putative program effectiveness, which may be less valid than EBPRs, to determine what is "evidence-based." Conclusion: Greater awareness of scientifically - based EBPRs and greater understanding of their advantages need to be fostered among state legislators and regulators charged with making policy to increase or improve the use of evidence-based programs and practices in behavioral healthcare in the U.S.
