The Self-Reportng Questionnaire (SRQ-20) is a screening scale frequently used in basic care to assess indicators of common mental disorders (CMD). The objective of this study was to investgate evidence of clinical validity of the SRQ-20, comparing clinical and non-clinical participants, and verifying its capacity to diferentate groups with specific psychiatric disorders, as well as to predict suicide risk. The study had 161 participants, of which 60% composed a clinical sample. Descriptive analyzes, correlatons, ANOVAs, logistc regression analysis and ROC curves were performed. Results showed a large effect size to SRQ-20 in diferentate clinical and nonclinical groups. Patents with mood or anxiety disorders did not difer from psychotcs in relaton to the number of common mental symptoms presented. Personality disorders presented significantly higher scores than other groups. SRQ-20 was also a good predictor of suicide risk. The scale has been shown to be a useful clinical tool, especially in brief evaluaton of CMD and possible signs of risk.
