I’ve seen some people saying cronbachs is overused and doesn’t actually measure consistency. Trying to see if or when that’s the case and if alternatives like omega is an option?

For example, making a new scale vs evaluating the effectiveness of item vs all the above, which is most appropriate and when? I seem to find sources that advocate purely for one or the other…

I understand the textbook definitions but in layman’s terms I can’t wrap my head around it. In a regression or a CFA, what does a DF actually refer to?
