The correlation coefficients between the subscales and the total scale, and between the subscales were analyzed to test the construct validity. The results are shown in Table 6-5. Table 6-5 shows that the correlation coefficients between the subscales and the total score are between 0.766-0.877, the correlation between each subscale was between 0.507 and 0.729, and all of them were significant at 0.01 level. The correlation between each subscale and the total scale was obviously higher than that between each subscale.
