Validation of a Greek adaptation of the 20-item Toronto Alexithymia Scale.
Compr Psychiatry. 2010 Jul-Aug; 51(4):443-8.CP

Abstract

BACKGROUND

The purpose of the current investigation was (1) to test whether the 3-factor structure of the 20-item Toronto Alexithymia Scale (TAS-20) corresponding to the theoretical conceptualization of the alexithymia construct could be recovered in a Greek translation of the scale (the TAS-20-G), (2) to assess if a 3-factor structure provides a better fit to the TAS-20-G compared with the recently proposed alternative factor structures, and (3) to evaluate the internal reliability of the TAS-20-G.

METHODS

The English version of the TAS-20 was translated into Greek and then back-translated and modified until cross-language equivalence was established. The Greek version was then administered to 340 university students. Confirmatory factor analyses were conducted, and 4 different factor structure models were compared. Internal consistency and item-to-scale homogeneity of the TAS-20-G and its factor scales were also evaluated.

RESULTS

The 3-factor model provided a good fit to the data and proved superior to alternative 1-, 2-, and 4-factor models. Apart from a coefficient alpha below the recommended range for the externally oriented thinking factor, the TAS-20-G and its factor scales demonstrated adequate internal consistency and homogeneity.

CONCLUSION

The TAS-20-G is a valid and reliable measure of alexithymia in university students and may be suitable for investigations of alexithymia in other Greek-speaking population samples.
