This paper describes the cross-validation of the German version of the 20-Item Toronto Alexithymia Scale (TAS-20) in normal adults (n = 306) as well as in a psychiatric inpatients sample (n = 101). The scale showed adequate estimates of internal consistency, split-half and test-retest reliability, and a three-factor structure comparable to that obtained for the English version of the TAS-20 which was found to be consistent with the main features of the alexithymia construct. Evidence of convergent validity of the German TAS-20 was demonstrated by significant positive correlations with conceptual related psychometric scales. The finding of significantly higher alexithymia scores in the psychiatric patients sample as compared to normal adults underlined the clinical validity of the German version of the TAS-20.
