Outcomes of clients with severe mental illness in a psychosocial and vocational rehabilitation program modeled after the Program for Assertive Community Treatment were tracked through record review to determine if clients' employment gains were sustained while they were in the program. A total of 184 clients participated in the program between December 1984 and February 1994, of whom 34 percent remained for one to four years and 33 percent remained for longer than four years. Sixty-four percent of the clients who stayed in the program a year or longer attained employment. The program maintained an average employment rate of 33 percent of all participating clients. More than half of the clients who held jobs worked part time and were employed more than half of the time that they were in the program.
