简要总结
The goal of this clinical trial is to learn if a behavioral "nudge" strategy, specifically a default option, can improve screening participation in populations at high risk for lung and stomach cancer. The main questions it aims to answer are:
- Does presenting a screening appointment as a default option increase the likelihood that high-risk individuals will choose to be screened?
- How do participants react, and what is their level of acceptance, when the nudge intervention is disclosed to them?
- Does this transparency (disclosing the nudge) change their subsequent screening decisions? Researchers will compare a default option group to a standard control group to see if the nudge effectively increases screening adherence.
Participants will:
- Read a short educational text about lung or stomach cancer and its screening.
- Complete an online questionnaire.
- Make a decision regarding a simulated cancer screening appointment.
- Read a disclosure explaining the behavioral nudge strategy used during the study.
- Re-evaluate their screening decision and answer questions regarding their attitude toward the nudge.

- •The informed consent statement was read and confirmed.
排除标准
- •Reading impairment preventing independent questionnaire completion.
- •Failure to pass attention checks and logical consistency tests embedded within the questionnaire.
结局指标
主要结局
Percentage of Participants Who Accept the Cancer Screening Appointment
时间窗: Immediately after the default option intervention
This outcome is assessed via a dichotomous choice (Yes/No) embedded in the simulated online scheduling system within the questionnaire. The value reported will be the percentage of participants who choose to accept and schedule the screening appointment.
次要结局
- Participant Attitude Score Towards the Default Option Nudge(Immediately after the disclosure of the intervention)
- Self-Reported Score of the Nudge's Influence on Decision-Making(Immediately after the disclosure of the intervention)
- Acceptance Score of the Default Option Nudge in Public Health Services(Immediately after the disclosure of the intervention)
- Percentage of Participants Who Accept the Appointment After Disclosure(Immediately after the disclosure of the intervention)
