Abstract
Objective:
Confounding and interaction have differing implications for the interpretation of findings and the design of research, mental health services, and policy. This study aimed to verify whether the association between sex and the use of services for mental health reasons is confounded or modified by social anchorage.
Methods:
We undertook a case–control study nested in Cycle 1.2 of the Canadian Community Health Survey. Cases were defined as users of general medical services for mental health reasons in the previous 12 months, and control subjects were defined as never-users of any services for mental health reasons. The pattern of social anchorage was described by the roles of parent, spouse, worker, and their combination.
Results:
Overall, women are 2.9 times more likely than men to use general services for mental health reasons. However, this inequality between women and men decreases substantially or subsides in individuals who are less anchored to Canadian society. For instance, in single parents and in unemployed parents, the odds of using general services for mental health reasons are similar in women and in men. The pattern of social anchorage tends to modify, but not to confound, the association between sex and the use of services.
Conclusions:
Ignoring the interaction between sex and the pattern of social anchorage distorts the interpretation of the inequality between women and men in the use of general medical services for mental health reasons and may affect the design of comprehensive mental health services and policy.
