How to design effective paper questionnaires
Creating an effective paper questionnaire requires considering both the respondent experience and the quality of collected data. Poor design can lead to dropouts or introduce bias, compromising result reliability. Here are some methods for designing questionnaires that guarantee quality data while meeting regulatory requirements.
Use the funnel method to structure your questions
The funnel method is an approach that involves starting with broad, general questions before gradually moving to more specific questions.
In practice, a well-structured questionnaire has three main stages. First, start with open and general questions that allow respondents to freely share their ideas or context. For example, if you’re evaluating customer satisfaction, a question like “How would you describe your experience with our service?” is ideal for opening the discussion.
Next, follow with transition questions that deepen the topics mentioned in general responses. Finally, end with closed and specific questions, designed to collect precise details necessary for your analysis.
Write comprehensible questions and instructions
Response quality directly depends on question clarity. Ambiguous or overly complex formulations can produce unusable data.
- Use simple and clear language, avoid jargon or technical terms. Each question should be understandable for all respondents, regardless of their knowledge.
- Formulate short and precise questions, addressing one topic at a time. For example, instead of asking “Are you satisfied with the quality and price of our products?”, divide this question into two for more precise responses.
- Provide explicit instructions for each type of question. For multiple-choice questions, specify whether one answer is expected or if multiple choices are possible. For rating scales, clearly explain what each level represents. For example: “On a scale of 1 to 5, where 1 means ‘very dissatisfied’ and 5 ‘very satisfied’.”
Don’t hesitate to include examples to illustrate the expected type of response, especially for open questions. Once your questions are written, evaluate the optimal duration to ensure a good response rate.
Define the right length and appropriate timeframes
Questionnaire length plays a crucial role in participation rate and response quality. Research shows that the ideal questionnaire duration is between 5 and 15 minutes.
For most questionnaires, a questionnaire containing 7 to 10 questions, with a total duration of 10 to 14 minutes, offers a good balance between comprehensiveness and engagement.
“The more questions you ask, the less time your respondents spend, on average, answering each question.”
To estimate duration, calculate the time needed to answer each question. Closed questions generally take 15 to 30 seconds, while open questions may require 1 to 2 minutes, depending on their complexity.
Clearly indicate the estimated duration at the beginning of the questionnaire. Then test the necessary time with a representative sample and adjust based on feedback. If your questionnaire exceeds 15 minutes, consider dividing it into thematic sections or removing non-essential questions. Focus on priority data for your objectives and reserve secondary questions for a future survey.
Prepare your paper questionnaires for digitization
Obtain optimal quality digitizations
Once your questionnaire is designed, it’s essential to prepare it correctly to guarantee precise digitization. Image quality plays a key role in optical character recognition (OCR) performance.
- Scanner settings: Configure your scanner to at least 300 DPI resolution. If your questionnaire contains smaller characters (less than 10 points), opt for a resolution between 400 and 600 DPI.
- Brightness: Adjust brightness to 50% to avoid areas that are too dark or too light that could impair reading.
- Alignment: Ensure the document is perfectly straight and aligned to avoid any distortion during capture.
For older or yellowed documents, activate RGB mode. This preserves all necessary nuances, which is crucial for reliable and precise data extraction.
By following these steps, you lay the foundation for efficient automated analysis and seamless data recognition.
Use AI tools to process your paper questionnaires
Once your questionnaires are digitized under optimal conditions, the next step involves leveraging artificial intelligence to convert these paper documents into ready-to-use data. Thanks to AI, you eliminate manual entry while improving processing accuracy and speed.
