This online course is called “Questionnaire Design for Social Surveys” and is based on a course created as part of the Joint Program in Survey Methodology and the Michigan Program in Survey Methodology at ISR. The original course - a core course in our MS program - is one of our most popular courses. It is offered every semester, and in every semester the course is over enrolled. Students with backgrounds in Journalism, Public Health, Criminology, Marketing, Communication, Sociology, Psychology, and Political Science are part of our regular audience. Why does the course have such broad appeal? Because questionnaires are everywhere. For instance, government agencies use questionnaires to measure the health of their nations, their economic wellbeing, and myriad other aspects of life to inform policy decisions. Nongovernmental organizations use questionnaires to measure their customers’ or members’ satisfaction, and pollsters use questionnaires to measure political attitudes and voting intentions. But designing questions that get good answers is harder than it looks. Indeed, there is now a large scientific literature dealing with how to design good questions. This course will cover the stages of questionnaire design: developmental interviewing, question writing, question evaluation, pretesting, and questionnaire ordering and formatting. It reviews the literature on questionnaire construction, the experimental literature on question effects, and the psychological literature on information processing. In addition, this course reviews the effects of essential design features on questions and questionnaires. Students will critique existing questions and questionnaires as part of the course.
