Psychometric properties of the Big Three Perfectionism Scale-Short Form (BTPS-SF) among Iranian University students

Abstract

Introduction: Perfectionism is a common personality trait, particularly among university students. As awareness of this trait increases, research seeks to update tools for measuring it. The psychometric properties of the three-dimensional perfectionism scale-short form (BTPS-SF) have not been studied in the Iranian population. Therefore, this study aims to investigate the psychometric properties of this 16-item scale among Iranian university students. Methods: The statistical population for this research included all students in Tehran. From this population, 528 students were selected, and data analysis was performed using SPSS 26 and AMOS 24 software. Results: The findings showed that the BTPS-SF has acceptable validity and reliability. Furthermore, a positive and significant correlation was found between perfectionism and interpersonal sensitivity, whereas a negative and significant correlation was found between perfectionism and self-compassion. Conclusion: Given the desirable psychometric properties of the Persian version of the BTPS-SF, its use can be recommended to psychology experts in research and clinical evaluation situations.
