Abstract

Alexithymia is highly prevalent in patients with substance use disorders (SUDs) and has been implied in SUD pathogenesis and treatment outcomes. However, the psychometric properties of the most-used instrument for evaluating alexithymia (the 20-item Toronto Alexithymia Scale, TAS-20) have been scarcely studied in relation to SUD patients.
