Comparing an AI avatar video versus a conventional narrated PowerPoint to teach patients about radiotherapy
Official title: Comparison of Patient Understanding and Anxiety According to the Delivery Method of Educational Videos: A Prospective Randomized Study in Radiotherapy Patients
Run by Yonsei University · NCT07550686 · Data updated 2026-11-12
This study will test whether an AI-generated avatar video helps adults scheduled for radiotherapy understand their treatment better and feel less anxious compared with a conventional narrated PowerPoint video.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 20 or older who are scheduled to undergo radiotherapy, have ECOG performance status 0-1, and can watch and comprehend video and audio are ideal candidates.
✕Probably not a fit
Patients who cannot complete questionnaires because of cognitive impairment or psychiatric disorders, or those unable to follow audio-visual material, are unlikely to benefit from the interventions tested here.

What this trial studies
In a randomized, parallel-group design, 136 patients scheduled for radiation therapy at two Yonsei-affiliated institutions will be assigned 1:1 to view either an AI-based avatar educational video or a conventional PowerPoint video with voice narration. Both videos are standardized to about five minutes and contain identical core messages and summary points. Participants complete questionnaires at baseline, immediately after viewing the assigned video, and during the first week of treatment to measure anxiety, knowledge comprehension, and satisfaction. The primary comparison focuses on post-intervention anxiety, with secondary analyses of knowledge, satisfaction, and changes over time.
Why it matters
Potential benefit: If successful, the AI-based video approach could reduce pre-treatment anxiety and improve patients' understanding of radiotherapy, making education more effective and patient-centered.
How similar studies have gone: Traditional educational videos have previously improved patient knowledge and sometimes reduced anxiety, but generative AI avatar delivery is novel with limited prior clinical evidence.
