Hello dear Prof./Dr. and fellow experts,
As i've gone through few items that i've selected from several sources for my survey questionnaires, i realise that there are few revisions to be made on the correct use of the language and structures.
I would like to know to what extent do researchers have the right to revise and to change the language forms and structures of items by other scholars as long as we don't change the context of these items.
Please advise.
Thank you.
