This month’s issue features three literature reviews on housing that highlight the importance of secure housing in recovery from serious mental illness. In the lead article, Debra J. Rog, Ph.D., and colleagues review the evidence base for permanent supportive housing, a much-studied intervention that provides affordable long-term housing to people with serious mental illness. Residents are also offered supportive services, but housing is not contingent on their service participation (page 287). In the second review, Sharon Reif, Ph.D., and colleagues examine research on recovery housing, which provides supervised short-term housing to help stabilize people with substance use disorders so that they can take their first steps toward recovery in a supportive environment. The authors found many gaps in the research base and recommend areas for further study (page 295). The third review, also by Dr. Reif and her colleagues, looks at residential treatment for individuals with substance use disorders, an intervention that provides a 24-hour level of structured care in nonhospital, freestanding facilities and allows residents to focus on intensive recovery activities. Residential treatment models vary widely, and the traditional 28-day model is fairly rare today. The authors echo the call of others for more rigorous research with greater specificity and consistency (page 301). The three articles are part of the SAMHSA-funded Assessing the Evidence Base Series, which updates research on commonly used interventions for people with serious mental illness. The articles, which were peer reviewed by a special panel of Psychiatric Services reviewers, will appear in the journal throughout 2014. Commenting on the three articles in Taking Issue, Sam Tsemberis, Ph.D., founder of Pathways to Housing, Inc., which developed the Housing First model, notes that an effective housing model “must be based on core principles and values: housing as a basic right, social inclusion, and equal access to social, cultural, educational, and employment opportunities.” Finally, in this month’s Open Forum, Kevin Martone, M.S.W., describes a housing crisis for people with serious mental illness—a crisis that occurs when the average national rent for a one-bedroom unit began exceeds the average monthly income of an individual receiving Supplemental Security Income. The consequences of the nation’s failed housing policy—incarceration and chronic homelessness—are often unfairly blamed on the public behavioral health system, the author notes (page 313).
