In this month's issue, Psychiatric Services continues its series on evidence-based practices with two articles. In the first, Stanley D. Rosenberg, Ph.D., and his colleagues review evidence that exposure to trauma is endemic among people with severe mental illness and that posttraumatic disorders are often unassessed or misdiagnosed in this population, even though valid assessment techniques are available. They outline a research agenda for ensuring that effective treatments are developed and broadly disseminated (see page 1453). In the second article, consumer advocate Frederick J. Frese, III, Ph.D., and his coauthors argue that "provider-centric" approaches to implementing evidence-based practices that fail to integrate the recovery model will not win the support of a substantial proportion of consumers and their advocates. They suggest ways that policy makers and providers can better integrate such practices and the recovery model (see page 1462). Robert E. Drake, M.D., Ph.D., and Howard H. Goldman, M.D., Ph.D., are editors of this series, which began in January 2001 and will continue into the coming year.
