Two papers in this issue examine the long-term effectiveness of supported housing programs for homeless persons in New York City. Frank R. Lipton, M.D., and associates conducted a five-year follow-up of almost 3,000 homeless persons placed in high-, moderate-, and low-intensity supported housing sponsored by the city. They found that 75 percent were continuously housed for one year and 50 percent for five years (see page 479). Sam Tsemberis, Ph.D., and Ronda F. Eisenberg, M.A., report on a five-year study of the Pathways to Housing program, which provides immediate access to independent scatter-site apartments for persons with psychiatric disabilities who are homeless and living on the streets. The study found that 88 percent of the program's tenants remained housed after five years, compared with 47 percent of residents in the city's residential treatment system (see page 487).
