I collected an open-ended questionnaire from 117 subjects but because most of the subjects are illiterate, I filled the questionnaire on their behalf. My questions are:
1. Can I consider the questionnaires as self-administered questionnaires even though I filled them in on patients behalfs?
2. By filling in the questionnaires for the patients, does that cause bias that might affect the results?
1. If you read the questions to subjects and copied exactly what they said into the questionnaire, it is considered interviewing not self-administered questionnaire
2. Yes, it does. However, the level of bias depends on what role you play on this study, how much influence you have on patients and the way you read the questions to them
Hi Ha Phan,
Thank you so much for your answer. To clarify more, the three open-ended questions are part of patient satisfaction questionnaire. My question is how to separate them from the self-administerated questionnaire and what about those patients who filled the questionnaire themselves?
As I understand, these patients are illitrate so they would not be able to read and fill in answers for any question in your questionnaire. They need to have someone read questions to them and then fill in the answers. Thus, these questionnaires are not considered as self - administrered questionnaires and they should be separated when doing analysis for those quesitons related to their opinions. I assume each questionnaire has unique ID so you know which ones are SA and which ones are not. Another way is when doing analysis, just do filter by education, then you will be able to separate them. Hope this helps.
Thank a lot for you clarification. could you please refer me to an article or even a book that guide researchers while asking or interviewing illiterate participants to include these information in methodology section.
