Description
Summary:	•Depression is an important public health concern around the world. In Brazil, the prevalence of this condition among its adult population is 5.8%.•A high self-report prevalence of depression has occurred among participants of the CUME project, whose value is two times higher than the one estimated for the brazilian population.•The depression diagnosis in CUME project was self-reported, and its agreement with that confirmed by the psychiatrist was 81%, with sensitivity of 80.6%, specificity of 81.4%, and kappa value of 0.62.•The self-reported diagnosis of depression by the participants of the CUME project displayed good accuracy and is valid for utilization in studies that address this health outcome with this population. Assess the reliability and validity of the self-reported diagnosis of depression of participants of the Cohort of Universities of Minas Gerais (CUME project). This cross-sectional study included 79 participants who answered the project's follow-up questionnaire in 2018. A team of four psychiatrists applied the DSM-5, using the structured clinical interview for mental disorders (SCID-5-CV) as a reference, in a face-to-face consultation with the participants, between October and November 2019. We calculated agreement (%) between self-reported and in-person psychiatrists medical depression diagnoses, sensitivity, specificity, false positives and negatives to both diagnoses, and performed the Kappa test. Most participants were young adults (60.8% aged between 20 and 39 years), not in a stable union (54.4%), graduates (75.9%), currently employed (72.2%), non-smokers (69.6%), and sedentary/insufficiently active (69.6%). Besides, high proportions of participants reported binge drinking (36.7%) and inadequate intake of carbohydrates (50.6%) and lipids (78.5%). The self-reported and in-person psychiatrist's medical depression diagnoses did not differ statistically, with an agreement of 81%, the sensitivity of 80.6%, the specificity of 81.4%, and the Kappa value of 0.62. The time between the self-report of depression and the psychiatrist's confirmatory diagnosis. The CUME project' participants self-reported diagnosis of depression displays good accuracy and is valid for utilization in studies that address this population's health outcome.
