A questionnaire is more than a simple list of questions. Well-written questions that are composed according to the principles outlined in Chapter 8 by Fowler and Consenza may need further modification as they are ordered and placed in questionnaires suited for a particular survey mode or a particular survey mode or a particular population of respondents. Turning a collection of questions into a questionnaire brings into consideration nonresponse concerns as well as measurement conserns. It raises issues of how communicating with respondents, visually, in mail and web surveys versus aurally in interviews, requires that adaptations be made. The design process may also encourage reordering of questions and the writing of connective language to help respondents grasp the intent of questions and how to respond to them. The logic and psychology of this process of turning a list of proposed survey questions into an acceptable questionnaire is the focus of this chapter.
