Study shows Housing First program significantly reduces homelessness over long term

The longest running study of its kind on the “Housing First” model has found that it significantly reduces homelessness over the long term compared to treatment as usual, according to a study published in The Lancet Psychiatry by scientists at the Centre for Addiction and Mental Health (CAMH) and St. Michael’s Hospital.

“The Housing First model results in a lasting and significant increase in the rate of days stably housed per year,” said lead author CAMH Physician-in-Chief Dr. Vicky Stergiopoulos. “We now have evidence that we can offer to policy makers, clinicians and other stakeholders about solutions to chronic homelessness for people with mental illness.”

Housing First provides immediate access to rent supplements and mental health support services to people who are homeless and have a mental illness. Traditional models require homeless people to stop using substances or receive psychiatric treatment before being eligible for housing support services.

This study published in The Lancet Psychiatry, which followed participants over a six-year period, is the first to show that Housing First continues to be significantly more effective than treatment as usual in the longer term, especially for those with high needs for mental health support services. After 6 years, that group had stable housing an average of 85% of the time in the previous year compared to 60% for the treatment as usual group.

“These results show that if we choose to do so, we can end chronic homelessness in a way that is life-changing for individuals and enormously beneficial for all of society,” said Dr. Stephen Hwang, Director of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital, where the study was conducted.
