Factors associated with common mental disorders: a study based on clusters of women.

Objective: to identify factors associated with common mental disorders (CMD) in a sample of adult women in Southern Brazil.

Methods: This population-based study, composed of 1,128 women, investigated socioeconomic, behavioral and health/disease explanatory demographic variables. Five response groups were explored: one group with common mental disorders - cut-off point 6/7 in the Self-Reporting Questionnaire 20 (SRQ-20) - and four others corresponding to the different clusters found using the latent class clustering technique, also from the SRQ-20.
