Hi Satchi,
I have used the scale starting with strongly disagree(1) to strongly agree (5). Not sure whether there are any strict rules regarding this.
I think in general it is best to use a questionnaire that already has been validated. To get published, I think this is important. If you have to develop the questionnaire yourself, I would use a validated questionnaire, which fits best with your research, as an example for structure. There are books which contain validated questionnaires regarding all kind of issues. Good luck:-)
