SUBJECTS AND METHOD: Psychometric properties of the questionnaire on a sample of 225 examinees have been calculated and the factor structure of indicators that make up the scale is presented. RESULTS: Psychometric properties calculated in an alternative way are significantly better than the original, especially when it comes to reliability and representativeness of the questionnaire. CONCLUSION: This method of data analysis raises the possibility of multivariate data processing on the Culig's questionnaire, which is important for further research.
