Incorporating a quiz into informed consent processes: Qualitative study of participants' reactions

Background Formal checks of participant understanding are now widely recommended to improve informed consent processes. However, the views of the participants these assessments are designed to protect are rarely considered. In this paper the findings of a qualitative study aimed at documenting community reactions to a semi-structured questionnaire ('quiz') are reported. The quiz was administered to 189 mothers after consenting for their children to participate in a malaria vaccine trial on the Kenyan Coast.
