Revised Competitiveness Index for use in China: Translation and Rasch analysis

To assess trait competitiveness, the 14-item Revised Competitiveness Index has become a frequently used measure, but to date it is not available in Chinese. The present study translated the instrument into Mandarin and tested its psychometric properties using Rasch analysis with a large sample of undergraduate students recruited from China. For the Enjoyment of Competition sub-scale, best fit to the Rasch model was obtained after discarding the misfitting items 1, 6, and 7. For the five-item Contentiousness sub-scale, suitable fit required two sub-tests. There was no evidence of threshold disordering or differential item functioning by personal factor for either of the sub-scales. These results support reliability and internal construct validity of an 11-item Mandarin version of the RCI.
