The construction of an interview schedule or questionnaire is a time consuming task requiring considerable attention to all the details. The investigator must make many decisions, including whether to use an interview schedule or a self administered questionnaire as well as how to balance open-ended and close-ended questions.

Questions for relevant content area are then drafted or borrowed or adapted from other instruments.
