Background and objective: Today, organ donation and transplantation play a critical role in saving patients with the advanced deficiencies of body organs. In the meantime, organ donation is influenced by a variety of cultural, social, and religious factors. They have an impact on individuals’ intention (tendency) to donate organs after brain death. This study examined factors affecting Qom Medical School students’ intention regarding organ donation. The examination was carried out based on behavioral intention model. Methods: This cross-sectional study was conducted on 304 medical students. They were selected by multiple-stage sampling technique from Qom Medical School. The research data was collected by a validated reliable questionnaire. It comprised questions regarding personal specifications, awareness, attitude, abstract norms, and intention. The collected data was analyzed by SPSS 18. Results were described by central statistical indices and analyzed using independent sample T-test, Pearson correlation coefficient, and linear regression (P<0.05). Results: Among participants, %12.83 of the students had donation card after brain death yet not the other %87.17. Mean organ donation awareness score was 5.87. Mean construct scores were 49.25, 16.11, and 1.27 respectively for attitude, abstract norms, and intention. Results indicated that there is a significant difference between two organ donation bank member and non-member groups in terms of awareness, attitude, abstract norms, and intention (P<0.05). There was also a direct significant correlation between awareness, attitude, and abstract norms regarding deliberate organ donation (P<0.05). Conclusion: most of the students under study were not a member of after-brain-death organ donation bank. Awareness and behavioral intention model constructs were moderate. Here, the constructs including awareness, attitude, and abstract norms could not predict %31 of variations in organ donation intention. Paper Type: Research Article.
