Questionnaires play a crucial role in research. They help us collect data which can reveal the hidden truth about individuals. But they do have 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 surveys offer a range of advantages, such as more reach than traditional mail or phone-based surveys and the capacity to reach a wide audience. They also pose challenges, including the difficulty in reaching a representative demographic sample. Additionally, they are subject to issues such as screen size, hardware platform, operating system and browser settings that may influence the responses.

When creating a questionnaire it is important to think about the research aims and objectives. When you’re creating questions, it’s essential to know your audience. For example you must know whether they can comprehend and respond to the questions or whether they have the time to finish a lengthy questionnaire.

To ensure that the new questionnaires are working as intended, it’s important to test them in advance using qualitative methods, such as focus groups, cognitive interviewing, or pretesting. Also, questionnaires may be susceptible to “question order effects” in which responses to questions from earlier ones can alter the answers to subsequent questions.
