Questionnaire Development

The survey form to be completed or the set of interview questions is the heart of any serious survey effort. Without a sound questionnaire, any project is destined to fail. Constructing the right questionnaire is part science and part art - and it depends on having hands-on experience as well as formal training.

Prerequisite to crafting an effective questionnaire is understanding the research objectives. Perhaps the most critical path to understanding is listening carefully to articulation of the objectives and, then, probing anything which is unclear, incomplete, or not expressed in a way that can be addressed through a survey. It is only after a thorough back-and-forth dialogue produces a set of researchable objectives that a first draft of the survey instrument should be attempted.

Of course, familiarity with the research topic also helps. Knowing the relevant issues and what types of questions are usually asked speeds the process. But specific subject matter expertise is not always necessary. What the survey specialist needs to know to develop the questionnaire (and, later, do the analysis) can often be acquired "on the job" via in-depth discussion with the client.

Questionnaire development is an iterative process of draft, review and comment, redraft, further review, and so forth, until a near-final version is ready to be tested. Pretesting is the next step for any new or substantially revised questionnaire. Resources dedicated to testing the questionnaire are always well spent. Thorough pretesting helps avoid costly mistakes and usually improves the validity, reliability, and utility of the data that will be collected.

Self-administered questionnaires (often sent and returned through the mail or completed online) are quite different than interactive interview questionnaires used in telephone and face-to-face surveys. GR&C has decades of experience with both types based on more than one hundred studies.
