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

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.

Psychometric properties of the full-form and short-form versions of the Integration of Stressful Life Experiences Scale (ISLES) among Iranian university students.

BACKGROUND: Making adaptive meaning of stressful life experiences has been identified as an important determinant of adjustment. The Integration of Stressful Life Experiences Scale (ISLES) was developed to assess the outcome of meaning-making processes in the face of negative events. AIMS: The psychometric properties of this scale have not been measured in Iranian populations. The purpose of the present study was to examine the psychometric properties of the 16-item and 6-item versions of ISLES with a sample of 502 university students who had experienced relationship dissolution. RESULTS: Findings support a two-factor structure with acceptable validity and reliability. Positive correlations between the scores of ISLES with Centrality of Event Scale and PTSD symptoms provided evidence of concurrent validity. CONCLUSION: The results of measurement invariance indicated that both the 16-item and 6-item versions of ISLES are gender invariant and can be used to assess meaning-made in both men and women.
