Results: During the investigation of content validity of the questionnaire, question number 14_related to possessing a cell phone_ and three subcategories of questions number 23, 24, and 25 were omitted due to their similarity in meaning with the other questions. Also, three options were added to the questionnaire so as to guard against ambiguities.
