Confirmatory factor analysis of the Chi-MPCOSQ. The indices used to examine the model fitness of the seven-domain structure were as follows: χ²/df = 3.07, the root mean square error of approximation =0.08, and the comparative fit index =0.93. These indices suggested that the model fitness was acceptable.
