Brief Summary

The goal of this study is to learn if sending text message invitations increases participation in colorectal cancer screening among 45-49 year olds in Yingge District, New Taipei City. It will also assess the effectiveness of this method. The main questions it aims to answer are:

• Does sending text message invitations increase the number of residents who complete fecal occult blood test (FOBT)? This study will compare a group receiving text message invitations to a control group receiving standard notifications to see if text messages are an effective way to increase screening rates. Participants will:
• Be randomly assigned to either receive text message invitations or standard notifications.
• The intervention group will receive an initial text and a reminder text one week later.
• The control group will receive standard notifications, and after one month will receive the same text message.
• The study will track who obtains a FOBT kit and who completes the test within a three-month period.
