In addition, it is o en much easier to validate an


           existing questionnaire than to develop a completely new


           questionnaire. This is because one of the most difficult


           steps for conducting a study involving the development of

           a new questionnaire is to establish a valid new set of


           questions and then confirm that these questions have a


           sufficient level of both reliability and validity. To do so, the

           researchers must have strong background knowledge of


           the subject matter in order to identify and select an


           appropriate set of questions when developing a new

           questionnaire from scratch. On the other hand, if the


           researchers choose to merely validate the translated


           version of an existing questionnaire, then the researchers

           will merely have to translate all the questions from the


           original questionnaire into a local (or native) language,


           which will then be followed by the process of determining


           both    the   reliability  and    validity  of   the   translated
