Objective: In this study, in order to assessment of alexithymia which showed strong relations with various medical and psychiatric/psychological disorders, was aimed determination in the Turkish sample of the psychometric proper-ties of the Perth Alexithymia Questionnaire (PAQ) which was developed according to the attention-appraisal model of alexithymia. Methods: For confirmatory factor analysis and internal consistency analysis, the participants are a total of 297, including 162 females (54.5%), 135 males (44.5%), age range 18-68 (33.01±11.77). Later, in other val-idity and the reliability analysis, including 268 persons of them consists of a total of 565 person students and society samples. Results: As a result of the confirmatory factor analysis made for the factor structure of the scale, the fit indexes of the five-factor model consisting of the dimensions of difficulty identifying negative and positive feelings, difficulty describing positive and negative feelings, and general-externally orientated thinking proposed in the nal study were found to be at an acceptable level. Test-retest reliability, linguistic, discriminative, predictive, and convergent validity findings showed strong psychometric properties. While the total score of the scale Cronbachs alpha internal consistency coefficient is 0.96, the Cronbachs alpha coefficients of the subscales vary between 0.85 and 0.90. Conclusion: It has been determined that PAQ has strong psychometric properties for use in Turkish culture and the scale is a valid and reliable measurement tool that will be used both in clinical settings and in re-search studies in the evaluation of alexithymia. The results of the study also provide clues that emotions should be evaluated positively and negatively in the evaluation of alexithymia. [Anadolu Psikiyatri Derg 2020; 21(0.200): 71-79]
