4.5.1 Validity of CSR scale

Firstly, after using the EFA method to analyze the 24 questions of the CSR part, we can see that the results of KMO and Bartlett's Test are shown in Appendix F: Output of validity analysis (CSR part). The KMO value is 0.896 (between 0.8 and 0.9), which falls into the range of being superb. The Bartlett's Test Chi-Square value is 1787.900 (df=276) and the significant level at 0.000, which means the R-matrix is not an identity matrix and. Therefore, these 24 questions suitable for factors analysis and there are some relationships between

After extraction, factor 1 accounts for 35.721% of variance (contributes to the most variance, as each successive factor will account for less and less variance), factor 2, factor 3 and factor 4 accounts for 7.759%, 5.660% and 5.342% respectively. Moreover, the eigenvalues of the factors after rotation are displayed at the column called “Rotation Sums of Squared Loadings” that factor 1 only makes up 5.338% of variance (compared to 2.691%, 2.618% and 2.428%
