This self-report measure is used to assess alexithymia, or difficulties identifying and describing one’s emotions, using the Toronto Alexithymia Scale (TAS-20). It is commonly applied in clinical and research settings to characterize emotion awareness and related cognitive style.
The instrument includes 20 items and typically requires about 3 minutes to complete. Items are designed to capture difficulties identifying feelings, difficulties describing feelings, and an externally oriented thinking style. Developed by R. M. Bagby, G. J. Taylor, and J. D. A. Parker, the Toronto Alexithymia Scale (TAS-20) can support case formulation and treatment planning by highlighting emotion processing features that may be relevant across a range of presentations.
