Questionnaires are an integral part of research that allows us to collect data that can reveal the hidden truths about individuals. However, they aren’t without 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 traditional surveys that are conducted by telephone or mail and the ability to include an international audience. They also have some problems, like the difficulty of reaching a representative sample of the population. Additionally, they are affected by issues such as screen size and operating system, hardware platform and browser settings that could influence the responses.
When creating a questionnaire, it is essential to take into consideration the research’s goals and objectives. When you’re creating questions, it is crucial to understand the target audience. For instance you should know whether they understand and respond to the questions or whether they have time to fill out a lengthy questionnaire.
It’s also important to test new questionnaires prior to their release by using qualitative methods, such as focus groups or cognitive interviews, or pretesting (often by using an opt-in form of survey) to ensure they’re performing in the way they were intended to. In addition, questionnaires are susceptible to “question order effects” where answers to earlier questions can affect the answers to questions that follow.
