Twenty-four grantees offered the RExO program, including national nonprofits, faith-based community organizations, community health organizations, and local or regional nonprofits. The exact bundle of services each grantee provided varied significantly. In all programs, case managers coordinated service delivery and supported participants. Most grantees offered group mentoring for participants, and a smaller subset offered individual mentoring.

The HWVP provided case management services and mental health RT to women veterans who were homeless or at risk of becoming homeless. The study authors defined RT as “a program that houses clients in a central location and provides clinical and social services to the clients while they are resident[s].” The program was implemented in eleven Veterans Affairs (VA) medical centers across the United States. The specific clinical and rehabilitation services varied by center, though all provided stable, safe housing and support from professional staff.
