How is cronbach alpha calculated
Web3. Cronbach's α is only designed for measures that are essentially τ -equivalent, which essentially means they contribute equally to the underlying construct. One way to test this is to see if they have the same factor loadings in a factor model. If your measures are not τ -equivalent, then α will underestimate reliability, regardless if ... WebDo I calculate the Cronbach's alpha for the pre-intervention and post-intervention separately (so two Cronbach alphas)? Or, I consider the 14 scales all together to obtain one Cronbach alpha? Which one makes more sense? Any suggestion is appreciated. Thank you in advance. intervention-analysis; cronbachs-alpha; Share. Cite. Improve this ...

If you wish to reverse items into the original scale you can compute: r j k = ( m a x j − m i n j) − x j k. Where m a x j and m i n j are the theoretical maximum and minimum values of item j, x j k is the score of individual k in item ...
