The seven measurement instruments included 79 items. Confirmatory factor analysis (CFA) was conducted to examine the validity of the instruments. The factors identified on each instrument were used to test a hypothetical model. CFA allows for assessing both the convergent and discriminatory validity of the instrument . Based on the CFA result, nine items with factor loadings of less than .50 were removed. The average variance extract of the items was 0.44-0.72. As the R2 value (.00e.41) for the factors was less than the average variance extract, the convergent and discriminant validity was confirmed .
