Toronto alexithymia scale: Adaptation of the Brazilian version to low-educated adults

Abstract

For the purpose of studying Alexithymia in low-educated adults, we intend to adapt the Brazilian version of the Toronto Alexithymia Scale (TAS-26) and to verify its internal consistency. With that aim, we translated the original TAS-26 (English) to Portuguese, adopting a colloquial language, without content distortion. An exploratory qualitative study interviewed 50 women (38-65 years, education <9 years) and identified comprehension difficulties in 22 items, that needed adaptation. A professional translator performed the back-translation of the adapted TAS-26, that was applied to a new sample of women (90 with chronical pain and 90 without pain, 38-65 years, education <9 years) to evaluate its internal consistency. Only four items (1/2/3/16) of the pre-existing Brazilian version (appropriate to university students) did not require modification. The internal consistency (Cronbach’s alpha) was satisfactory for total score (0.65) and elevated for factor 1 (0.87). The adapted Brazilian version of TAS-26 is appropriate to low-educated adults.
