Using Confirmatory factor analysis requires checking for convergent and discriminant validity, as well as reliability. As shown in Table III, the unidimensionality for each construct was validated since the critical ratios of the regression weights of the items exceeded 1.96 (Anderson and Gerbing, 1988). In addition, the significant factor loadings were evidences of convergent validity (Anderson and Gerbing, 1988). The AMOS output represents the t-values as CR values. The convergent validity was supported because all the CR values in Table III were statistically significant.
