Abstract
The TorontoAlexithymiaScale TAS20 is used worldwide as a valid measurement of alexithymia Until now populationbased standardization and cutoff values of the German TAS20 version have not been available This study provides these by means of a representative German sample and by investigating the factorial structure of the TAS20 Data were generated from a representative random sample of the German general population 1859 subjects aged between 20 and 69 The TAS20 sum score was normally distributed The mean value was 495 SD = 93 in men and 482 SD = 92 in women Divorce single and low social status were associated with enhanced sum scores Ten percent of the population exceeded the TAS20 sum score threshold of ≥61 The 66th percentile reached 53 for men and 52 for women Factor analysis identified three factors that match the scales of the English original version An additional fourth factor “importance of emotional introspection” was extracted Total explanation of variance by these four factors was 5227 The sum score of the German TAS20 version is suited for the standardized measure of alexithymia For selecting alexithymic individuals in experimental studies the cutoff ≥61 is possibly too restrictive Therefore we propose the 66th percentile for the identification of high alexithymics The TAS20 sum score is associated with important sociodemographic variables The factorial structure is reliable the fourth factor “importance of emotional introspection” provides differentiation of content and allows for enhanced explanation of variance
