We have previously described the design and development of a questionnaire. It is important to establish the validity of a questionnaire before it is administered to a population. A series of inter-related tests are required to determine the validity of a questionnaire. Questionnaires pass through an iterative process that includes the development of items, testing of the validity, revision of items, revision of the conceptual basis of the test, retesting, and repetition of the process till the questionnaire is finalized. The process of validation of a questionnaire continues if the questionnaire is in use. In this manuscript, we briefly describe the conceptual basis of the different methods that are used to establish the validity of questionnaires and item retention and exclusion.
