To evaluate the level of adherence to antidepressant therapies and associated factors in patients with depressive disorders. a cross-sectional analytical study was conducted in patients diagnosed with depressive disorders. The sample was for convenience, and a survey including sociodemographic, clinical, and therapeutic variables was designed. The Morisky-Green test, Beliefs about Medicines Questionnaire, and Simplified Medication Adherence Questionnaire were also used, all of which have been validated for assessing adherence in patients with depression. The qualitative variables were evaluated with absolute and relative frequencies, and a bivariate analysis was performed. This study included 54 patients with an average age of 49.5 ± 13.7 years, and 83.3% were women. All patients were diagnosed with major depression, and 9.25% also had an anxiety disorder. According to the Morisky-Green test, only 37% of patients were compliant with the drug therapy, although this was not statistically significant. Women were less compliant than men (33.3% versus 55.6%; p = 0.21). The beliefs that patients have regarding medication do not have a great impact on adherence to antidepressant therapy. However, it was evidenced that adherent patients had less doubts about the medication administered in comparison to non-adherent patients.
