Cross-cultural alexithymia Validity of the 20-item Toronto Alexithymia Scale in North American aboriginal populations.

摘要

OBJECTIVE: The generalizability of the alexithymia construct to North American aboriginal culture was examined by assessing the replicability of the factor structure of the 20-item Toronto Alexithymia Scale (TAS-20) in two different adult samples. The study also assessed the reliability of the scale and the influence of gender, age, and education on alexithymia levels. METHOD: The first sample was a community-based group of 123 aboriginal men and women; the second sample was 102 male aboriginal offenders. Both samples completed the TAS-20. RESULTS: The replicability of the three-factor structure for the TAS-20 was supported in both groups using confirmatory factor analysis (CFA). The TAS-20 and its three factors demonstrated adequate internal reliability, and the variables of gender, age, and education accounted for small or nonsignificant amounts of variability in total TAS-20 and factor scale scores. CONCLUSION: The results provide additional support for the factorial validity of the TAS-20 in diverse cultural groups.
