reversed, inverted items... MANOVA


New Member
Do I necessarily need to recode my inverted (negatively worded) items before running a MANOVA? I am running the MANOVA on all items of a questionnaires to see if there is a general difference between two groups ( Hotelling's T?) and will analyse the item level afterwards.

I do not fully understand how the MANOVA calculates the composite score.

Thank you for your help
