To explore intervention strategies aimed at improving community residents’ knowledge of colorectal cancer screening, their health beliefs, and screening rates.
A randomized controlled trial was conducted from December 2024 to March 2025, recruiting eligible community residents in Chengdu, Sichuan Province, for the intervention study. The navigation intervention protocol was developed based on the Health Belief Model and the Transtheoretical Model.
A total of 113 community residents participated in the study, comprising 56 in the intervention group and 57 in the control group. Prior to the intervention, there were no statistically significant differences between the two groups in terms of demographic characteristics, colorectal cancer screening knowledge scores, scores on the various dimensions of health beliefs, screening intention scores, or colonoscopy screening status (P>0.05). Three months after the intervention, there were group effects, time effects, and interaction effects between the two groups regarding colorectal cancer screening knowledge scores, health belief scores (perceived susceptibility, perceived severity, perceived benefits, and perceived barriers), and screening intention scores (P<0.001). At the end of the first and third months of the intervention, the intervention group’s community residents had higher scores for colorectal cancer screening knowledge (P<0.001), perceived susceptibility (P<0.001), perceived severity (P<0.05), perceived benefits (P<0.05), and screening intention (P<0.001) than those in the control group, while perceived barriers were lower (P<0.001). At the end of the first month of the intervention, there was no statistically significant difference in colonoscopy screening rates between the intervention group and the control group (P>0.05); however, by the end of the third month of the intervention, the difference became statistically significant (P<0.05).
The navigation intervention program based on the “HBM+TTM” theory can effectively improve community residents’ knowledge of colorectal cancer screening, their health beliefs, and screening rates, and it serves as a model for other regions to follow.
