This study had two aims. Firstly, the psychometric properties of the 20-item Toronto Alexithymia Scale TAS-20 and the Alexithymia Questionnaire for Children AQC that measure the three dimensions of alexithymia DIF, difficulty identifying feelings; DDF, difficulty describing feelings; EOT, externally-oriented thinking were explored in various samples of children, adolescents or young adults to detect the best factor-structure and to examine if the Externally-Oriented Thinking EOT factor must be deleted or not. Secondly, the capacity for adolescents to distinguish between alexithymia and depression was studied using factorial analyses of items of self-report of alexithymia and depression scales. Four groups were examined 80 healthy children, 105 adolescents with various psychiatric disorders, 333 healthy older adolescents and 505 young adults recruited from universities. The first two groups filled out the AQC and the latter two the TAS-20. Confirmatory factorial analyses CFA showed that the two-factor model DIF, DDF provided acceptable fits and had significant advantages over the three-factor model DIF, DDF, EOT. Low alpha coefficients for the EOT subscale were reported range from 0.18–0.61. Except for the children sample, exploratory factorial analyses EFA were performed on the items of the TAS-20 or AQC without the EOT items and the Beck depression inventory-II BDI-II or the Zung Self-Rating Depression Scale SDS. The items of the AQC and BDI-II or items of the TAS-20 and SDS loaded on separate factors with only a minor overlap suggesting that adolescents were able to differentiate alexithymia and depression when self-assessments were used. Alexithymia can be reliably assessed in adolescents using the TAS-20 or AQC without the eight items rating the EOT dimension.
