For complex and sensitive issue, we specifically use paper-based questionnaires which allow us to explain complicated concepts to respondents and verify the answers. Furthermore, when some target populations may not be receptive to online questionnaires, paper-based questionnaire can be an ideal solution. After choosing enough respondents with various demographic conditions, we distribute the questionnaires to them by hand, ensuring that clients will have a needed number of questionnaires completely and precisely answered by respondents.


This sort of testing is optimal for complex survey requiring clear clarification and high precision. Besides, it is effective for research on a target population of seniors, hospital patients, rural residents, remote locations residents, etc., who have little or no access to computers. For clients who have concerns over confidentiality with web-based surveys, paper-based questionnaires are a good alternative.
