Methods: Brazilian undergraduate medical and psychology students comprising the sample (n=184) completed the following measures: Cognitive Distortions Questionnaire, Beck Depression Inventory and Beck Anxiety Inventory. These self-report instruments were administered collectively in classrooms. Results: The Cognitive Distortions Questionnaire showed adequate internal consistency (Cronbach's alpha=0.85) and concurrent validity with Beck Depression Inventory (r=0.65, p<0.001) and Beck Anxiety Inventory (r=0.52, p<0.001). Furthermore, it was able to discriminate between groups possessing depressive (Beck Depression Inventory composite score ≥12) and anxious (Beck Anxiety Inventory composite score ≥11) indicators from those not possessing them (p<0.001). Principal components showed the measure was unidimensional, and it explained by IRISMAR REIS DE OLIVEIRA, MD, PhD; CAMILA SEIXAS, PhD; FLÁVIA L. OSÓRIO, PhD; JOSÉ ALEXANDRE S.
