BACKGROUND: Colorectal cancer (CRC) is the third most common cancer in men and the fourthmost common cancer in women in Iran. Therefore, the aim of this study was to determine the effectof educational intervention based on the theory of planned behavior (TPB) on the improvement ofCRC screening intention among average‑risk individuals.MATERIALS AND METHODS: This quasi‑experimental study was performed on the 50–69‑year‑oldindividuals referred to Asadabad city clinics in 2020. The individuals were randomly assigned tomultistage cluster sampling in each intervention and control group. The instrument used in thisresearch was a researcher‑made questionnaire based on TPB. Educational intervention wasconducted for the intervention group, one of their family members, and staff of clinic under intervention.Finally, the data were entered into SPSS and analyzed utilizing descriptive and analytical statistics.Results were considered significantly <0.05.RESULTS: There were no significant differences between two intervention and control groups in thepreintervention phase in terms of the mean scores of attitude (P = 0.58), subjective norms (P = 0.59),and behavioral intention (P = 0.66). However, in the postintervention phase, these differences weresignificant. Furthermore, regarding the mean score of perceived behavioral control, there was asignificant difference between the two groups in the preintervention phase (P < 0.02), while in thepostintervention phase, this difference was not significant (P = 0.29).CONCLUSION: Educational intervention based on the TPB has been effective in improving the CRCscreening intention among average‑risk individuals. Therefore, using the results of this researchand developing appropriate educational programs at the community level can be increased theparticipation of community members in CRC screening programs.
