Q: How is considered a questionnaire which is not 100% completed; considering that the interviewed person may not wish to provide answers to all the questions? A: Not all questions need to be answered. A person may decide not to answer some of the questions, particularly sensitive questions but if most of the questionnaire is answered, this will be considered a completed interview.

Q: How many persons will be re-contacted in the second set? A: All the persons contacted in the initial set. Q: Which is the difference in the second questionnaire from the first one?
