Toronto Alexithymia Scale-Tas: Reliability and Validity of the Portuguese Version
Main Article Content
Abstract
The purpose of this study was to estimate the degree of reliability and validity of the Portuguese version of the Toronto Alexythymia Scale-TAS. Subjects (N=581) were 394 female and 187 male undergraduate students. The Alpha Coefficient to the whole sample (0,71), as to the female (0,72) and male (0,71) sub-samples pointed to the index of precision of the scale while the inter-items coefficient (0,08) to the items’ homogeneity. The factorial analysis showed four factors compatible with those of the TAS’ Spanish version, which had already proved to be congruent with the English version. Results suggest that, from a psychometric point of view, the TAS’ Portuguese version can be considered a reliable and valid measure of the construct, as its English and Spanish preceding versions.
