Audiovisual Augmentation of Electronic Consent to Improve Consent Rates and Comprehension

Does adding audiovisual content to text-only electronic consent improve participant consent rates or comprehension compared with standard text-only consent?In this randomized clinical trial including 1535 participants, consent rates were similar across text-only, text plus physician video, text plus patient video, and text plus animated video groups, with no statistically significant differences. Among 884 participants who consented, overall comprehension of the consent process was high (86%) and did not differ significantly by consent strategy.Audiovisual augmentation of electronic consent did not improve consent uptake or understanding over text-only consent.
