Questionnaires play an essential role in research. They let us gather data that could reveal hidden information about people. However, they 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, like the ability to reach a wider audience than traditional phone or mail-based surveys and the capacity to engage a global audience. They can also present some challenges, including the difficulty of reaching a representative demographic sample. And they can be affected by issues such as screen size, hardware platform, operating system, and browser settings that can influence responses.
When creating a questionnaire, it’s important to carefully consider the research objectives and goals. It’s also important to consider the audience you’re asking for them, like whether they are able to comprehend and respond to the language you use or if they have the enough time to fill out a lengthy questionnaire.
It is also crucial to test new questionnaires before they are released through qualitative methods like focus groups or cognitive interviews. pretesting (often using an opt-in survey) to ensure they are working in the way they were intended to. Questionnaires are susceptible to «question-order effects» in which answers to earlier questions can influence the responses to subsequent ones.
