Animated Storytelling to Promote Colorectal Cancer Screening

This online randomized controlled trial will evaluate whether a short animated storytelling video increases behavioral expectation to obtain colorectal cancer screening among screening-eligible U.S. adults who report not yet having completed screening. Participants will be recruited via Prolific and randomized in Stanford Qualtrics to view either a brief animated video or a time-neutral informational text. Outcomes will be assessed immediately after exposure.
