Abstract
Background: Perfectionism, a multidimensional trait, impacts psychological well-being with both adaptive and maladaptive effects. Existing tools, such as the Frost Multidimensional Perfectionism Scale (FMPS) and Hewitt and Flett Multidimensional Perfectionism Scale (HMPS), face limitations in non-western contexts, including Iran. The Big Three Perfectionism Scale–Short Form (BTPS-SF), a concise 16-item scale, retains the core dimensions of perfectionism while enhancing usability in large-scale studies. Objectives: This study aimed to translate and validate the Persian version of the BTPS-SF, providing a reliable, culturally adapted tool for research and clinical applications in Iranian populations. Methods: This psychometric validation study employed advanced validation methods to assess the factor structure and psychometric properties of the short form of the BTPS-SF among Iranian adults. A sample of 1,271 participants, aged 18 to 50, was selected from Karaj using cluster sampling. Data collection involved the BTPS-SF and BTPS, with rigorous translation and cultural adaptation processes. Validity and reliability were assessed through content, concurrent, and construct validity, as well as internal reliability measures. Data analysis was conducted using SPSS 18 and Lisrel 8.8 software. Results: The BTPS-SF demonstrated robust content validity, with content validity ratio (CVR) and Content Validity Index (CVI) values exceeding the established benchmarks. Concurrent validity revealed a strong positive correlation (r = 0.82, P = 0.001) between the BTPS-SF and BTPS scores. Exploratory factor analysis (EFA) confirmed a three-factor structure, explaining 70.77% of the variance. Confirmatory factor analysis (CFA) demonstrated an excellent model fit, with a root mean square error of approximation (RMSEA) of 0.035 and a Comparative Fit Index (CFI) of 0.99. The scale demonstrated high reliability, with Cronbach's alpha values ranging from 0.887 to 0.916, and split-half reliability coefficients of 0.940, confirming its robust psychometric properties. Conclusions: The Persian BTPS-SF is a valid and reliable tool for assessing multidimensional perfectionism in Iranian adults. Despite limitations, such as self-reporting, the geographic focus on Karaj, and the cross-sectional design, the findings provide a solid foundation for future studies. Expanding the sample and adopting longitudinal designs could further refine its applicability across diverse contexts.
