Question #4
How can we end homelessness among people with serious mental illnesses?


Research has provided a substantial amount of information on what services and practices are effective in ending homelessness for people with serious mental illnesses. 1 The key is to:

  • Encourage the adoption of evidence-based practices for services, treatment, and prevention of homelessness;
  • Establish partnerships with Federal agencies, state and local governments, and public and private agencies to reduce barriers to services and increase resources and funding; and
  • Conduct research that addresses important gaps in knowledge. 2

We know what works

  • Outreach, whether in shelters or on the street, is effective. 3 Given the opportunity, most people who are homeless and have serious mental illnesses are willing to accept treatment and services voluntarily. Consistent outreach and the introduction of services at the client’s pace are key to engaging people in treatment and case management services. A consistent, caring, personal relationship is required to engage people who are homeless in treatment.
  • Integrated mental health and substance abuse treatment provided by multidisciplinary treatment teams can improve mental health, residential stability, and overall functioning in the community. Regular assertive outreach, lower caseloads, and the multidisciplinary nature of the services available on these teams are critical ingredients leading to positive treatment and housing outcomes. 5
  • Providing supportive services to people in housing has proven effective in achieving residential stability, improving mental health, and reducing the costs of homelessness to the community. Supported housing is preferred by many homeless people with serious mental illnesses. Many people who are homeless and have serious mental illnesses can move directly from homelessness to independent housing with supports. However, the transition from homelessness to housing is a critical time that needs intensive support and attention. 5
  • Prevention. Homelessness among people with serious mental illnesses can be prevented. Discharge planning to help people leaving institutions to access housing, mental health, and other necessary community services can prevent homelessness during such transitions. Ideally, such planning begins upon entry into an institution, is ready to be implemented upon discharge, and involves consumer input. Providing short-term intensive support services immediately after discharge from hospitals, shelters, or jails has proven effective in further preventing recurrent homelessness during the transition to other community providers. 6
