ارزیابی روانسنجی یک ترجمه فارسی مقیاس کمال گرایی بزرگ سه

Perfectionism as a personality trait has a multidimensional nature. Providing a new multidimensional measure of perfectionism, Smith, Saklofske, Stoeber, and Sherry (2016) developed the Big Three Perfectionism Scale (BTPS). The BTPS has shown very good psychometric properties, yet has not been subjected to psychometric analyses across cultures. The present research aimed to translate and validate the BTPS in Iran. The present investigation examined the factor structure of the BTPS using exploratory factor analyses as well as its convergent validity and facet- and factor-level reliability coefficients in Study 1 (275 university students). The structure and the higher-order models of the BTPS using confirmatory factor analyses were examined in Study 2 (298 community adults). Evidence of the convergent validity in a community sample was also replicated in Study 2. Overall, the current findings provided support for the psychometric properties of the Farsi translation of the BTPS in Iranian population. Consequently, this newly developed measure may be used in clinical and research settings in Iran.
