This measure assesses alexithymia, a personality construct associated with difficulty identifying and describing one’s own emotions and a tendency toward externally oriented thinking. The Toronto Alexithymia Scale (TAS-20) is a self-report questionnaire consisting of 26 items and typically requires about 25 minutes to complete.
Results are commonly used to characterize emotional awareness and perceived capacity for emotional expression in clinical and research contexts. Interpretation should consider the respondent’s reading level, current distress, and response style; the Toronto Alexithymia Scale (TAS-20) is not designed as a stand-alone diagnostic instrument. Development is attributed to Bagby, R.M.; Ryan, D.P.; Taylor, G.J.
