Crafting an effective questionnaire can be daunting for those just starting their research journey. If you’re a beginner and feel unsure about questionnaire design, this guide is meant for you. We provide comprehensive, concise, and informative guidance to help you kickstart your questionnaire design process.

In this blog, we’ll explore key elements to consider when designing an effective questionnaire, guiding you through the process—from selecting the right question types to enhancing clarity and relevance. By the end, you’ll be able to create a suitable questionnaire that meets your research objectives and design requirements.

1. What exactly is a questionnaire?

A questionnaire is a structured set of well-thought-out questions designed to collect information from respondents about a specific research topic. In some contexts, such as clinical research, questionnaires may be referred to as Case Report Forms (CRFs). Questionnaires can be administered in various formats, including paper-based, online, and face-to-face. No matter the format, their purpose is to collect data that can be analyzed to draw conclusions, test hypotheses, or inform decision-making. Designing an effective questionnaire is crucial for obtaining reliable and valid data that will enhance the overall quality of your research.

2. Why you should design an effective questionnaire

By carefully considering your questionnaire design, you add significant value not only to your final research output but also to the broader research community. A well-designed questionnaire leads to better data, more reliable conclusions, and a smoother research process. Here are several key reasons to invest time and thought into getting your questionnaire design right:

The language should be clear and simple. A well-structured questionnaire avoids ambiguity by using simple, direct language, which enhances data accuracy, consistency, completeness, reliability and validity by reducing response bias from the participants. The more participants understand your questions, the more they can provide complete and reliable responses. Design your questionnaire with the participant in mind, consider their level of education, language proficiency and preferences, and sociocultural contexts. A good questionnaire should therefore be sufficiently comprehensible to the participant. One way to ensure this is to pre-test earlier versions with several typical model participants and adjust accordingly. Also consider engaging colleagues or experts who understand the context in the development phase of the questionnaire design.

Design for Purpose: A good questionnaire aligns with the goals of your study, ensuring that all responses are purposeful, relevant and meaningful. Avoid trying to capture too much information that might not be relevant in answering your research question(s). By staying focused on your research goals, you save your time but also, the participants’ time and avoid poor questionnaire completion rates.

Strive to engage the participant: A well-organized questionnaire captures the respondent’s interest, leading to more thoughtful answers and detailed responses. The structure, phrasing and flow of your questionnaire design should be such that the participant finds it interesting and engaging enough to follow through till the end. So, a well-designed questionnaire will anticipate questions that can disrupt rapport with the participant. For example, push sensitive questions like sexual behaviour and finances to the end, and bring forth less triggering questions ahead.

Make statistical analysis easier: Well-designed questionnaires have structured questions leading to organized answers, simplifying the statistical analysis to draw clearer conclusions. By collecting data in the appropriate format, you ensure that the data are suitable for applying the suitable statistical analysis methods. Involve a statistician in the early stages of the design using a well statistical analysis plan.

Example: If you want to measure attitudes or opinions, using a Likert scale (e.g., “Strongly Disagree” to “Strongly Agree”) allows you to quantify responses. For instance, a question like “How satisfied are you with the training?” with a 5-point Likert scale (1 = Very Dissatisfied to 5 = Very Satisfied) generates numerical data that can be easily analyzed using statistical methods like mean, median, or regression analysis (linear for continuous variables and you can categorize the responses to perform logistic regression).

Uphold Ethical standards always: Design your question with ethical considerations in mind. In study procedures ensure all responses are preceded by informed consent and that the questions do not violate ethical principles. Therefore, a good questionnaire should ensure the respect of participants’ confidentiality, privacy and autonomy; which builds trust with respondents and ensures compliance with ethical research standards.

A good questionnaire becomes a model for future studies: If you design your questionnaire effectively with validity and reliability, it can serve as a model for future studies who need a similar tool to assess the aspect of interest. Other researchers can refine your questionnaire and build on its successes, enhancing the quality of subsequent research efforts for the production of new data.

3. Essential Parts of a Good Questionnaire

A questionnaire is made up of three key parts:

3.1 The Introduction:

This is a brief explanation of the study’s purpose and objectives. It gives instructions on how to complete the questionnaire and information about confidentiality and how the data will be used. A consent statement is necessary.
Example: “Thank you for participating in our research on healthcare accessibility. This survey will take approximately 15 minutes to complete. Your responses will remain confidential and will be used only for research purposes. By proceeding, you consent to participate in this study.”

3.2 Demographic questions:

These questions are designed to gather information about the respondent’s background. Sociodemographic questions are typically asked in a straightforward and non-intrusive manner to ensure respondents feel comfortable providing accurate information. Here’s how they are commonly asked:

Age: Can be asked in ranges (e.g., “What is your age group? 18-24, 25-34, 35-44, etc.”) to avoid making respondents uncomfortable about disclosing their exact age.

Gender: Typically includes options like “Male,” and “Female,” in our context.

Education Level: Presented as a multiple-choice question with options such as “No education,” “Primary,” “Secondary,” and “University”.

Employment status: Often asked with predefined categories (e.g., “Student,” “Employed Full-Time,” “Self-Employed,” “Unemployed,” “Retired,” etc.).

3.3 Content questions:

There are 3 types of questions: closed–ended questions where the respondents choose from a list of predetermined options (Examples: multiple-choice, Likert scale questions), open-ended questions where respondents provide answers in their own words, and a combination of both formats to capture a wide range of information while maintaining some consistency in responses.

4. Types of Questionnaires

Questionnaires can be classified into different types based on several characteristics. Understanding these different types will help you choose the most appropriate format for your research needs. Let’s explore the main categories:

4.1 Questionnaire Format Types

4.2 Questionnaire Administration Methods

4.3 Questionnaire Question Types

By understanding these different questionnaire types, you can select the most appropriate approach based on your research objectives, target population, and available resources.

Now that you’ve got the basics of designing effective questionnaires under your belt—from understanding their purpose to mastering question types like open-ended and multiple-choice—you’re well on your way to collecting meaningful data. But how do questionnaires stack up against other tools like interviews or surveys? Curious to find out?
