en Evaluation of Fecal Immunochemical Test (FIT) Screening and Its Determinants: A Descriptive Study Based on the Extended Parallel Process Model, 2025 Epidemiology Original Article <div style="text-align: justify;">Background: Fecal immunochemical test (FIT) as the primary diagnostic method, and colorectal cancer screening (CCS) as the most important measure for early detection and prevention of colorectal cancer (CRC), are influenced by multiple determinants. <a name="_Hlk205450805">The present study aimed to ascertain FIT screening behavior among teachers along with its determinants using an extended parallel process model (EPPM).</a> Materials and Methods: The cross-sectional study was undertaken among 202 teachers over 45 years of age in Rafsanjan city (southeast of Iran) using simple random sampling method. The study tool was a questionnaire based on the structures of the EPPM which were collected virtually. The data were analyzed using SPSS-25 software and by the statistical tests of Chi-square, independent t-test, univariate and multiple logistic regression at a significance level of 0.05. Results: In this study, 7.5% of teachers had undergone FIT over the past three years and 92.5% had not undergone screening. In the final model of logistic regression analysis, a bachelor's degree (Adjusted OR: 0.09, 95% CI: 0.02–0.46, P=0.003) and a master's degree (Adjusted OR: 0.09, 95% CI: 0.02–0.37, P=0.001) were associated with a significant decline in the odds of screening compared to an associate degree. Further, self-efficacy was significantly linked to an increase in the odds of screening (Adjusted OR: 1.05, 95% CI: 1.00–1.10, P=0.042). Conclusion: The findings suggest the need to further investigate related determinants, including beliefs, attitudes, and perceived barriers. In addition, theory-based health promotion interventions grounded in models such as the Extended Parallel Process Model (EPPM), self-efficacy theory, and the Health Belief Model (HBM) should be developed, implemented, and rigorously evaluated.</div> Screening, Colorectal Cancer, Teacher, Extended Parallel Process Model. 40 47 http://johe.rums.ac.ir/browse.php?a_code=A-10-970-1&slc_lang=en&sid=1 Mona Hafezi Bakhtiari mona_hafezi@yahoo.com 22400319475328460013637 22400319475328460013637 No M.Sc.
