Limitations of Questionnaires and Web Experiments

Web-based questionnaires and questionnaires are a crucial method of epidemiology that provides crucial information on the condition of health and disease in the public. They are a popular method of collecting data, which is often less expensive and time-consuming than face to-face interviews, paper questionnaires mailed, or automated telephone menu systems. Questionnaires and Web experiments are not free of limitations, which should be addressed to ensure reliable and accurate results.

A questionnaire can be affected by response bias. This is the tendency of respondents to answer questions based on their personal opinions and not on research goals. Additionally, questionnaire design can influence responses in a variety of ways: for example, question wording may influence whether respondents are able to comprehend and interpret the question in the same manner (reliable) and also, determine what you’re looking for (valid) or are able to answer accurately (credible).

Respondents might also experience survey fatigue or lack of engagement with the questions being asked which decreases the probability of them offering honest answers.

Online questionnaires also pose a challenge for some experiments, for example, positioning or reaction time studies. It is difficult to control and measure the same variables across people due to the variations in browser settings, operating systems, and the size of screens.

Additionally, surveys conducted on the Web are only accessible to those who are keyboard and Internet knowledgeable, which currently isn’t a large portion of the population. It is also difficult for Web researchers debriefing participants after the experiment window has ended.
