MOTS CLÉS Adolescence ; Alexithymie ; TAS-20 ; Analyse factorielle confirmatoire ; Développement Résumé L’objectif de cette étude est d’examiner la structure factorielle et la consistance interne de la TAS-20 sur un échantillon d’adolescents (n = 264), ainsi que de décrire la distribution des caractéristiques alexithymiques dans cet échantillon. La structure à trois facteurs de la TAS-20 a été confirmée par notre analyse factorielle confirmatoire. La consistance interne, mesurée à l’aide d’alpha de Cronbach, est acceptable pour le premier facteur (difficulté à identifier les sentiments (DIF)), bonne pour le second (difficulté à verbaliser les sentiments (DDF)), mais en revanche, faible pour le troisième facteur (pensées orientées vers l’extérieur (EOT)). Les résultats d’une Anova mettent en évidence une tendance linéaire indiquant que plus l’âge augmente plus le niveau d’alexithymie (score total TAS-20), la difficulté à identifier les sentiments et les pensées orientées vers l’extérieur diminuent. En ce qui concerne la prévalence de l’alexithymie, on remarque en effet que 38,5 % des adolescents de moins de 16 ans sont considérés comme alexithymiques, contre 30,1 % des 16—17 ans et 22 % des plus de 17 ans. Notre étude indique donc que la TAS-20 est un instrument adéquat pour évaluer l’alexithymie à l’adolescence, tout en suggérant quelques précautions étant donné l’aspect développemental de cette période. © L’Encéphale, Paris, 2007.
