What is the difference of Cronbach's Alpha and McDonald's Omega?

01 January 1970 1 947 Report

I am a little bit puzzled with the differences between Cronbach's Alpha and McDonald's Omega.

I would be grateful if fellow ResearchGate colleagues could provide explanations about the differences between both concepts.

Thank you in advance.

Best Regards,

Riangga.

Cronbachs should be used on unidimensional scales. Thats one of the differences i can come up with.
