We frequently test new survey questions ahead of time through qualitative research methods such as focus groups, cognitive interviews, pretesting (often using an online, opt-in sample), or a combination of these approaches. We also track opinion on a variety of issues over time so we often ensure that we update these trends on a regular basis to better understand whether people’s opinions are changing.Īt Pew Research Center, questionnaire development is a collaborative and iterative process where staff meet to discuss drafts of the questionnaire several times over the course of its development. For Pew Research Center surveys, this involves thinking about what is happening in our nation and the world and what will be relevant to the public, policymakers and the media. The first is identifying what topics will be covered in the survey. There are several steps involved in developing a survey questionnaire. Here, we discuss the pitfalls and best practices of designing questionnaires. Pretesting a survey is an essential step in the questionnaire design process to evaluate how people respond to the overall questionnaire and specific questions, especially when questions are being introduced for the first time.įor many years, surveyors approached questionnaire design as an art, but substantial research over the past forty years has demonstrated that there is a lot of science involved in crafting a good survey questionnaire. Surveyors may conduct pilot tests or focus groups in the early stages of questionnaire development in order to better understand how people think about an issue or comprehend a question. Researchers are also often interested in measuring change over time and therefore must be attentive to how opinions or behaviors have been measured in prior surveys. Designing the questionnaire is complicated because surveys can ask about topics in varying degrees of detail, questions can be asked in different ways, and questions asked earlier in a survey may influence how people respond to later questions. Questionnaire design is a multistage process that requires attention to many details at once. Creating good measures involves both writing good questions and organizing them to form the questionnaire. Accurate random sampling will be wasted if the information gathered is built on a shaky foundation of ambiguous or biased questions. Perhaps the most important part of the survey process is the creation of questions that accurately measure the opinions, experiences and behaviors of the public.
