Assessing Reliability and Validity of the Farsi Version of the Toronto Alexithymia Scale in a Sample of Substance-Using Patients

Abstract

The aim of this study was to estimate reliability and factorial validity of the Farsi version of the Toronto Alexithymia Scale–20 (TAS–20) for 321 substance-abusing patients (187 men and 134 women). All were asked to complete the Farsi version of the Toronto Alexithymia Scale–20, the Emotional Intelligence Scale, and The Mental Health Inventory. Analysis supported the internal consistency, test-retest reliability, concurrent validity, and three-factor structure of the Farsi version of the TAS–20 for substance users. The factors are similar to the three reported previously and were labeled as Difficulty Identifying Feelings, Difficulty Describing Feelings, and Externally oriented Thinking. These results provide evidence for applicability of the TAS–20 and its cross-cultural validity
