The 1 percent program disappeared when the federal Community Mental Health Centers Program was block-granted to the states in 1981. With the formation of the Substance Abuse and Mental Health Services Administration (SAMHSA) in 1992, NIMH gave up its demonstration authority. Initially, SAMHSA continued the research demonstration program, along with some efforts by private foundations that supported multisite demonstrations. Since the late 1990s, however, there has been a steady attrition of research demonstration programs in favor of single-site development grants. Most recently SAMHSA stopped conducting rigorous evaluations of its demonstration programs almost entirely.
