Questionnaires are an integral part of research that allows us to collect data that can reveal the hidden truths about people. However, they do have their limitations.

Questions can be self-administered, with participants answering all questions themselves, or researcher-administered, where the research team interviews a sample of respondents by phone, in-person, or online. Self-administered questionnaires tend to have lower response rates than researcher-administered questionnaires, due in part to the impersonal nature of mailed paper surveys and automated telephone menu systems.

Web-based questionnaires offer a number of advantages, including greater reach than traditional telephone or mail-based surveys and the capability to engage a global audience. But they can also pose several challenges like the difficulty of reaching a representative sample. They can also be affected by issues such as screen size, hardware platform, operating system and browser settings that could influence the responses.

When you design a survey it is important to think about the research goals and objectives. It’s also essential to know your audience when creating questions that ask if they are able to understand and answer the language you use or if they have enough time to fill out a lengthy questionnaire.

It is also crucial to test the new questionnaires ahead of time by using qualitative methods, such as focus groups or cognitive interviews. testing them in the pretesting phase (often with an opt-in survey) to ensure they’re working according to their intended purpose. Finally, questionnaires can be susceptible to “question order effects” in which responses to earlier questions could affect the answers to later ones.
