Abstract: Rasch analysis is a probabilistic model used to calibrate and validate scales during the development and measurement of standardised tests. Its general principles and applications were determined in this research on the basis of a version of the 24-item psychological capital questionnaire (PCQ). The validation of the original PCQ was extended by collecting data from 438 intercollegiate sport employees, after which the Rasch rating scale model was used to examine the data. Overall, the findings regarding model-data fit, differential item functioning, and convergent validity evidence provided additional support for the suitability of the psychometric properties of the PCQ as a starting point in assessing the psychological states of sport employees. The findings also reflected the wide application potential of Rasch analysis in the assessment of sport management studies.
Keywords: Rasch model; scale calibration; sport employees; psychological capital; psychological capital questionnaire; PCQ.
