Researchers experience and views on participants’ comprehension of informed consent in clinical trials in Malawi: a descriptive qualitative study

Abstract Background Informed consent is the cornerstone of research ethics. One of its goals is that participants enter research with an understanding of what their participation entails. This paper is a study on how researchers understand the informed consent process. Previous studies have looked at this topic from a research participant perspective. However, few studies focus on the perspectives of the researchers. Therefore, this is an important paper that highlights an important issue (informed consent) from the perspective of those who administer it during research. Methods In-depth interviews were conducted with 18 researchers from 3 different research centers in Malawi working in clinical trials. The data was analyzed using open code utilizing the thematic approach to qualitative data. Results This study identified that researchers have good awareness of the role of informed consent, how important it is for participants to understand the given information and ways to adjust their practice accordingly when obtaining it in order to enhance participant understanding. According to the research staff, most participants do not really understand all the concepts of the study at the initial visit, they gain more understanding during subsequent visits. It was emphasized that the best method of facilitating informed consent is reading the informed consent to the participant, thus a face-to-face conversation. Long and complex informed consent was identified as one of the barriers to participant understanding of the informed consent. Shortening the informed consent form and having additional conversation with the participants was suggested as one way of improving participant comprehension. Conclusion Most of the participants understand much of the information during subsequent visits as you keep reminding them since informed consent is an ongoing process. Existing relationship or trust between a participant and a researcher, may influence participants’ decision and misguide their understanding on the purpose of the study. Adequate time should be allocated to informed consent discussions. Shortening the informed consent forms and having additional conversations with potential participants may help improve their understanding.
