" Can I modify a questionnaire to adapt it to my needs ? "

MAPI Research Trust views:

For consistency and interpretation of results, you should not modify a questionnaire by deleting or adding an item, modifying the response choice, the ordering of items, the recall period, or any other modifications which have to do with the content and substance of the questionnaire unless you have received written authorization from the original developer.
