Questionnaires play an essential role in research. They let us collect data which could reveal hidden information about individuals. 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 surveys offer a range of advantages, including greater reach than traditional phone or mail-based surveys, and the ability to reach a wider audience. They also pose issues, such as the difficulty of reaching a representative sample of the population. They can also be affected by factors such as screen sizes and platforms for hardware operating systems, browser settings.

When creating a survey, it is crucial to think about the research goals and objectives. When creating questions, it’s important to know the target audience. For example you must know whether they can comprehend and respond to the questions or do they have the time to complete a long questionnaire.

To ensure that the new questionnaires are functioning as intended, it’s essential to test them prior to use using qualitative methods such as focus groups, cognitive interviewing or pretesting. Questionnaires are prone to “question-order effects”, where answers to questions from earlier ones can affect the answers to subsequent ones.
