We are in our country Saudi Arabia translate the English Questionnaire to Arabic, then 2 or 3 consultants in the same specialty review it, then the Arabic version translated again to English by neutral person ( prefer official translation office ) to ensure exact translation.
Sorry, I am talking in general, not specifically about this questionnaire.
Research need effort, I advise you to follow the steps I mentioned and you will get the Arabic version of the questionnaire. Researchers after that will get benefit of your effort.
