This longitudinal study with a matched comparison group was conducted in Abitibi, an area in North-West Quebec. Its goal was to observe the impact of community support services on the quality of life of long term psychiatric patients living in a remote area. A cohort of 47 subjects, living in a small town with a comprehensive network of community support services, was compared with a similar group living in a neighbouring city with only outpatient services. The satisfaction with life domains scale developed by Andrews and Withey and adapted by Baker and Intagliata was used at four times during the study. According to the results, the subjective perception of the quality of life in the two groups is comparable, even though the objective conditions are less favorable for the group participating in the community support program. The highest ratings were given to the place of residence, the neighborhood and its commodities; the lowest ratings were given to their love life and financial situation. One can observe a stability of the measures of quality of life over time and for the two groups. The perceptions of the sample living in a remote area are much more favorable than the ones of a comparable group living in the Montreal area. These results are discussed in a double perspective: the role of community support services in the daily life of people who are having severe and persistent problems of mental health, and the interest of measures of quality of life.
