Using a cartoon questionnaire to improve consent process in children: a randomized controlled survey.

Using audio and animated cartoon questionnaire is a more effective and standardized tool of content delivery to children. This study expanded the use of an animated cartoon to a children's survey. Audio and animated cartoon questionnaire (AACQ) can improve the child's understanding, increase children's engagement in biospecimen donation compared to text questionnaire (TQ) group, and enhanced their risk awareness of donating biospecimens. More AACQ should be used with children in the future to effectively deliver content to children and improve children's participation in the survey.
