An investigation of the psychometric properties of the 26 item Toronto Alexithymia Scale in a Japanese culture.

We investigated the psychometric properties of the Japanese version of the 26 item Toronto Alexithymia Scale in a Japanese culture, testing a sample of 1,008. The validity and reliability of this Japanese version were suggested by significant correlations with the Beth Israel Hospital Psychosomatic Questionnaire and estimates to test-retest and internal consistency. These results suggest that this version may be suitable for Japanese populations. Although alexithymia scores were correlated negatively with increasing age, the result, based on the large sample, seems to be of minimal significance.
