The effectiveness of patient navigator intervention in promoting the uptake of colorectal cancer screening for the average risks older adults in Hong Kong: a pilot study

Phase 1

1. Develop a training program for lay navigators in facilitating CRC screening uptake.
2. Evaluate the effectiveness of the training program in improving the knowledge of CRC of the lay navigators by completing pretest and posttest related to the CRC knowledge.
3. Evaluate the self-efficacy of lay navigators in providing PN intervention by completing pretest and posttest of self-efficacy scale.
4. Evaluate the satisfaction of the program by the lay navigators after training. Phase 2
5. Develop and implement an evidenced-based PN intervention to enhance the uptake of CRC screening for the average risk of older adults in Hong Kong.
6. Evaluate the feasibility and acceptability of PN intervention by assessing the screening rate, recruitment rate, percentage of eligibility, consent rate, withdrawal rate during recruitment, attrition rate of the participants and satisfaction rate of the participants.
7. Evaluate the preliminary effect of the PN intervention by the uptake rate of the CRC screening of the average risk older adults compared to control arm at baseline and 3 months after the intervention.
8. Determine the preliminary effects of PN intervention on knowledge, perceived susceptibility, severity, benefits and barriers on CRC screening.
