Challenges and Advantages of Questionnaires and Web Experiments

Questionnaires are a vital part of research and allow us to gather data that can reveal the hidden truths 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 a wider audience than traditional surveys conducted by mail or telephone and the ability to reach an international audience. However, they do pose several challenges including the challenge of reaching a representative sample. They are also affected by issues such as screen size, hardware platform, operating system and browser settings that can influence the responses.

When you design a questionnaire it is important to think about the research objectives and goals. When designing questions it’s important to know your audience. For example you must know if they can understand and respond to the question or whether they have time to complete a lengthy questionnaire.

To ensure that the new questionnaires are working as intended, it’s important to test them prior to use by using qualitative methods such as focus groups, cognitive interviewing, or pretesting. Questions are susceptible to “question-order effects” which means that answers to earlier questions may influence the answers to subsequent ones.
