Why do some researchers in psychometrics still use the "Little Jiffy" approach (PCA + Kaiser rule + Varimax)?

This approach is used even when exists papers where give alternatives procedures, who are more useful because focus on variance of construct, not in variance of error like the PCA.

Please read this aritcle:

Structural equations modeling: Fit Indices, sample size, and advanced topics,

A. S. M. M. Hoque

If the correlation value is more than .85 in two exogenious variables than descrimenent validity will not achieve and fitness indices will be affected. So be careful about the redandency among items to achieve all the fit indices.
