Step 5: CFA was run using the validation sample (n = 250) to assess convergent validity

and discriminant validity. A construct with indicator loadings greater than 0.5, a signi-

cant t value (t > 2.0), or both was considered to have convergent validity (Chau 1997).

Step 6: Discriminant validity was assessed by comparing the χ

statistics for the

unconstrained and constrained models. In the unconstrained model, the correla-

tions among constructs were freely estimated, while in the constrained model, we

xed the correlation between each pair of constructs to be 1, while freely estimat-

ing the other correlatio ...
