Colorectal Cancer Screening
Conditions
Brief summary
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in behavioral expectation (simple and next-step) to obtain colorectal cancer screening, as measured by a 7-item visual analogue scale. | Baseline, immediately post-intervention exposure (up to 24 hours) | Participant self-reports their likelihood of discussing, scheduling, or obtaining colorectal cancer screening after exposure to assigned study material. Total scores range from 0-70 with higher scores indicating greater behavioral expectation (Item 7 is reverse scored). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in knowledge about colorectal cancer screening and colonoscopy, as measured by a 5-item knowledge questionnaire. | Baseline, immediately post-intervention exposure (up to 24 hours) | Self-reported knowledge regarding colorectal cancer screening and the preventive role of colonoscopy, including detection and removal of pre-cancerous polyps. Response options are true/false/not sure, with 1 point per correct answer and 0 points for incorrect or "not sure". Total scores range from 0-5, with higher scores indicating higher knowledge. |
| Change from baseline in perceptions and beliefs about colonoscopy, as measured by a 13-item scale. | Baseline, immediately post-intervention exposure (up to 24 hours) | Self-reported perceptions an beliefs about colonoscopy include perceived susceptibility, perceived severity, perceived benefits and perceived barriers. Responses will be compared on a Likert scale that ranges from 1-5 (Strongly disagree / Disagree / Neither / Agree / Strongly agree), where higher scores indicate more positive perceptions and beliefs, with the perceived barriers section reverse scored. |
