This study tested the hypothesis that users of mental health self-help services would be more satisfied with professional mental health services than clients who did not use self-help services. A survey was administered to 311 clients of professional mental health services, 151 (49 percent) of whom were users of self-help services. A multiple regression model showed that the use of self-help services was associated with greater satisfaction with professional mental health services. This finding provides support for the idea that the use of self-help services encourages appropriate use of professional services. The study provided evidence that self-help and traditional mental health services can function complementarily rather than in competition with one another.
