[Homelessness, mental health and occupational therapy.].

Persons who are homeless with a mental illness constitute a significant portion of the homeless population. They have a myriad of occupational performance problems and are further compromised by systemic and political issues. There is growing evidence that occupational therapy can make a contribution to the health and quality of life of this marginalized, under served population. This paper describes the process and challenges providing occupational therapy services to persons who are homeless with mental health problems, addictions, and serious mental illnesses using the Canadian Model of Occupational Performance. There is a goodness of fit between the values and beliefs of the occupational therapy profession and the needs and occupational performance issues of persons who are homeless. Through helping people to develop meaningful occupations and gain control of their lives, people may be able to make permanent and positive changes in their lives. Within this dynamic is a great deal of potential learning and growth for human beings regardless if they are providers or recipients of service.
