Questionnaires are a vital element of research and allow us to gather data that will allow us to discover the hidden truths 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 surveys have many advantages, such as a greater reach than surveys that are conducted by telephone or mail and the ability to include an international audience. However, they also come with issues, such as the difficulty of reaching a representative sample of the population. They can also be subject to issues like screen size, hardware platform, operating system and browser settings that can affect responses.
When designing a questionnaire, it is important to think about the research goals and goals. When designing questions, it’s crucial to know the target audience. For instance it is important to determine whether they understand and respond to the questions or if they have the time to finish a lengthy questionnaire.
To ensure that new questionnaires are functioning as intended, it is important to test them before hand by using qualitative methods such as focus groups, cognitive interviewing or pretesting. Questionnaires are prone to “question-order effects”, where answers to earlier questions can influence the answers to later ones.
