Various studies on the conceptual framework of perfectionism construct use Hewitt Multi-dimensional Perfectionism Scale (HMPS), as a basic approach. The measure has a prominent role with respect to the theoretical considerations of perfectionism dimensions. This study aimed to evaluate the psychometric properties of the Turkish version of the scale. 479 undergraduate volunteers participated in this study. In this study, demographic questionnaire, Hewitt Multi-dimensional Perfectionism Scale (HMPS), Padua Inventory (PI_R), Obsessive Beliefs Questionnaire (OBQ-44) were administered. The original three factor structure was tested for the Turkish version of the scale by using confirmatory factor analysis. Convergent validity of the measure was evaluated. Internal consistency and 15- day temporal stability were computed in order to assess reliability of the measure. The confirmatory factor analysis replicated the validity of the three factor structure for the data obtained from Turkish sample. The measure has adequate reliability and validity in Turkish students.
