I am adapting questionnaire cross-cultural. Questinonnaire has 11 item and two factor. I want to confirm the structure
1 item's corrected item total correlation is <.20. Should this item be deleted before cfa?
If you have an existing hypothesised structure which you wish to test whether derived from theory or from previous work then the appropriate method to do that is CFA. There does not seem to be any pressing reason to do a preliminary item analysis as is you remove an item what you will be testing then in your CFA is not the hypothesised model but one derived from it in a data dependent way.
