WebCronbach's coefficient alpha is the most widely used estimator of the reliability of tests and scales. However, it has been criticized as being a lower bound and hence underestimating true reliability. A popular alternative to coefficient alpha is composite reliability, which is usually calculated in conjunction with structural equation modeling. WebCronbach’s alpha is the best standard used for assessment of internal consistency reliability. Cronbach’s alpha of ~0.7 appears sufficient, and values of 0.8 and greater indicate high internal consistency of the tool. 29 In the present study, the values of Cronbach’s alpha obtained for the whole scale and for its dimensions were ...
