ResumoInternationally, the most widely used self-report instrument to assess alexithymia (a clinical condition characterized by serious deficits in the cognitive processing of emotions) is the Toronto Alexithymia Scale (TAS-20). Because this measure has been poorly investigated in Brazil and emerging research suggests that TAS-20 scores might vary from one culture to another, we sought to: (1) investigate the psychometric properties of a Brazilian TAS-20; and (2) examine the degree to which Brazilian non-clinical TAS-20 scores differ from the scores of non-clinical samples from other cultures. A sample of 850 non-clinical Brazilian adults were administered a number of questionnaires and performance-based measures via online data collection. Data analyses inspected internal consistency and factor structure of the TAS-20, and tested the association of TAS-20 scores to emotional functioning and psychopathology. In line with previous international research, the Brazilian TAS-20 showed acceptable to adequate psychometric properties. Furthermore, TAS-20 scores associated negatively with empathy and emotional perception, and positively with emotion dysregulation and personality traits like dependency, abrupt changes in mood, and avoidance of criticism. Also noteworthy, our non-clinical Brazilian TAS-20 scores were very similar to those observed in other previously published non-clinical TAS-20 scores from seven non-Brazilian cultures.
