Mental disorders have a high prevalence among people who seek care in health facilities for physical ailments without being properly identified and treated. The Self Report Questionnaire (SRQ) has been designed to detect possible cases and is widely used in the primary care field.

The responses to the SRQ-27 and its relationship with the presence of anxiety and depression, established by the Mini Neuropsychiatric Interview, were analyzed using descriptive statistics, association tests, and AUC-ROC analysis of each item.

Nine other, common to both disorders, also showed to be effective (AUC ROC >0.60) in their identification.
