- Abstract
Aims: The aim of this study was to examine the factor structure and the validity of the Turkish version of the 20- item Toronto Alexithymia Scale (TAS-20) developed by Bagby et al. in a student sample. Methods: Healthy undergraduates or post-college graduate students (n=390) from Karadeniz Technical University Medical School or the Institute of Health Education, respectively, were assessed using confirmatory factor analysis. Cronbach's alpha coefficient was determined to estimate internal reliability of the TAS-20 and subscales and correlations between each item and total score were also calculated. Results: The Turkish TAS-20 showed a three-factor model. The Cronbach alpha for the total TAS-20 scale was 0.78, and for the three subscales (factors 1-3); 0.80, 0.57, and 0.63, respectively. Three of four criteria of goodness-of-fit met the standards for adequacy-of-fit. The parameter estimates for the items and correlation between the three factors of the TAS-20 were as follows: between factors 1 and 2, 0.53; between factors 1 and 3, 0.12; between factors 2 and 3, 0.36. All items (except 18 and 20) correlate significantly with the total score, the values range from 0.22 to 0.48. Conclusions: The Turkish TAS-20 factor analysis yielded a three-factor structure consistent with the original scale and its translation had adequate internal consistency. Thus, the TAS-20 scale is a valid construct within the Turkish culture.
