Way to asses Common Method Bias in GSCA

[123 456]

Hi all, 

I have a quick question regarding assessing Common Method Bias in GSCA. Is there any way to assess CMB in GSCA? Currently, I am using Harman's single factor approach to assess CMB. Will that be adequate enough for GSCA ?

Best regards,

Maybe one option is the "dimensionality" information in construct Quality measures.

You can create a factor with all the items and check if dimensionality remain at 1 (if more than 1 dimensions is recommended then CMB is less probable)
