Financial Incentives and Motivational Intervention to Improve Gastric Cancer Screening in China

In the financial incentive group, participants will receive reimbursement for transportation, accommodation, and food costs, along with RMB 200 (about 30 US dollar) to compensate for potential income loss due to endoscopy, provided they undergo the endoscopy.

For the motivational intervention group, researchers will provide detailed information about the social norms surrounding endoscopy screening, including the prevalence of screening participation, the potential risks of gastric cancer, and the health benefits of screening.

Participants in the mixed intervention group will receive both financial incentives and motivational intervention.
