Questionnaires are an essential element of research and allow us to gather data that can reveal undiscovered insights about individuals. 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 surveys have many advantages, including a wider audience than traditional surveys that are that are conducted by telephone or mail and the ability to engage an international audience. They also have some challenges, including the difficulty of reaching a representative sample of the internet-based.org/questionnaires-as-a-poll-instrument/ population. They are also affected by factors such as screen dimensions, hardware platforms operating systems, browser settings.

When creating a survey, it is important to consider the research goals and objectives. When you’re creating questions, it is crucial to understand the target audience. For instance you should know whether they can comprehend and answer the language or if they have the time to fill out a lengthy questionnaire.

It’s also important to test new questionnaires prior to their release using qualitative methods such as focus groups, cognitive interviews, or pretesting (often by using an opt-in form of survey) to ensure they’re functioning in the way they were intended to. Additionally, questionnaires are susceptible to “question order effects” where the answers to earlier questions may affect the answers to subsequent questions.
