Although several patient education materials on colonoscopy preparation exist, few studies have evaluated or compared them, and hence no professional consensus on recommended content or media to use.


We aimed to address this need by developing and evaluating a new video on colonoscopy preparation.


We developed a new video explaining split-dose bowel preparation for colonoscopy. Of similar content videos on the Internet (n=20), the most favourably reviewed video among patient and physician advisors was used as the comparator for the study. 232 individuals attending gastroenterology or urology clinics reviewed the new and comparator videos. The order of administration of the new and comparator videos was randomly counterbalanced to assess the impact of presentation order. Respondents rated each video along the following dimensions: information amount, clarity, trustworthiness, understandability, new or familiar information, reassurance, information learned, understanding from patient’s point of view, appeal, and likelihood to recommend the video to others.


Overall, 71.6% preferred the new video, 25.0% preferred the comparator video, and 3.4% were not sure. 64% of those who viewed the new video first, preferred it, while 78% who viewed the new video second preferred it. Multivariable logistic regression analysis also demonstrated that participants were more likely to prefer the new video if they had viewed it second. Participants who preferred the new video rated it as more clear and trustworthy compared with those who preferred the comparator video.


This study developed and assessed the strengths of a newly developed colonoscopy educational video.
