A 2006 series of studies in Canada compared individuals who participated in CSIs with those who did not. The two groups were comparable at baseline on a wide range of demographic variables, self-reported psychiatric diagnosis, service use, and outcome measures. After a year and a half, those who had participated in CSIs showed significant improvement in social support and quality of life (daily activities), less days of psychiatric hospitalization, and more were likely to have stayed in employment (paid or volunteer) and/or education. There was no significant difference on measures of community integration and personal empowerment, however. There were some limitations to the findings; although the active and nonactive groups did not differ significantly at baseline on measures of distress or hospitalization, the active group did have a higher mean score and there may have been a natural pattern of recovery over time for that group (regression to the mean). The authors noted that the apparent positive impacts of consumer-run organizations were achieved at a fraction of the cost of professional community programs.
