A different view to perfectionism: An investigation of the psychometric properties of the big three perfectionism scale in a Turkish community sample

Among the various instruments used in literature, the Big Three Perfectionism Scale (BTPS) is designed to meet the need for a comprehensive and current tool for the measurement of perfectionism and the assessment of personal tendencies. The present study adapts and examines the psychometric properties of the Turkish versions of both the BTPS-45 and BTPS-16, based on the responses of 427 Turkish community adults who were recruited for the purpose. All of the respondents were assessed with the two popular perfectionism scales, and for dark personality features and psychological problems, while 109 re-completed the BTPS-45 and BTPS-16 scales for the evaluation of test-retest reliability 2 weeks later. The results of the confirmatory factor analysis conducted to test the various models with different factor structures showed that the models comprising the three main and 10 sub-dimensions of the BTPS-45 and three main dimensions of the BTPS-16 showed the best fit. The significant relationships found between the BTPS factors, the scores recorded from the other perfectionism scale, the dark triad and the psychopathology symptoms all supported the validity of both the BTPS-45 and the BTPS-16. The findings further indicated that the structures of these forms had acceptable internal consistency and demonstrated satisfactory test-retest reliability. The reliability and validity of the Turkish versions of the long and short forms of the BTPS were thus established, supporting their use in further empirical studies and psychological interventions.
