Abstract
Only around 50-75% of individuals fully understand the various aspects of informed consent in research. The aim of our study was to examine whether supplementing the conventional paper-based informed consent process with an audiovisual aid improves participants’ understanding of the informed consent process and the information conveyed to them. Participants from two mental health/substance use intervention development studies were recruited for this study through consecutive sampling. They were then administered the traditional paper information and consenting process by itself or in combination with a video depicting the procedures of the study. Subsequently a bespoke questionnaire was administered to assess the participants’ understanding of the information conveyed to them about the parent study. The various domains of the questionnaire were compared between those who were administered the two different consenting processes using the chi square test. 27 (58.7%) participants were administered the traditional consenting process and 19 were administered the video-supplemented consenting process. The video-supplemented consenting process was not superior to the traditional paper-based informed consent process on any of the domains examined. In settings with participants having a limited education, and in research involving people with mental health or substance use problems, further research is necessary to identify of contextually relevant best practices for the informed consent process.
