Challenges and Advantages of Questionnaires and Web Experiments

Questionnaires are an essential part of research and allow us to gather data that can reveal undiscovered insights about people. However, they are not without 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 have a number advantages, such as a greater audience than traditional surveys that are conducted by mail or telephone and the ability to engage an international audience. However, they can also present a few challenges, such as the difficulty of reaching a demographically accurate sample. And they can be subject to issues such as screen size and hardware platform, operating system, and browser settings, which could influence responses.

When designing a questionnaire, it is important to think about the research goals and the goals. It’s also important to consider the people who will be answering your questions for them, like whether they are able and respond to the questions you have asked them to answer or if they’ve got the enough time to complete a lengthy questionnaire.

It is also crucial to test new questionnaires ahead of time using qualitative methods such as focus groups, cognitive interviews, or testing them in the pretesting phase (often using an opt-in survey) to ensure they’re working according to their intended purpose. Questionnaires are prone to “question-order effects” where the answers to earlier questions could influence the responses to subsequent ones.
