Introduction: Skin cancer is one of the most common cancers and the best way to prevent it is to protect yourself from the sun. The aim of this study was to study the factors determining the preventive behavior of skin cancer based on the extended parallel process model in medical students in ۲۰۲۱. Methods: This descriptive study was conducted on ۱۹۶ students of Shahrekord Azad University School of Medical Sciences. Random sampling was applied according to students' field. A questionnaire based on the extended parallel processes model was used to collect information, and data was analyzed using analysis of multiple linear regression. Results: The mean and standard deviation of age of participants were ۲۱.۸۴ ±۴.۱۹. According to the findings, the perceived intensity structure had the highest score among the model structures. Among the constructs of defensive avoidance model (β = ۰.۴۴۵) and self-efficacy (β = ۰.۴۲۴), the strongest predictor was behavioral intention (p < ۰.۰۰۱) and behavioral intention (β = ۰.۶۶۹) was the strongest predictor of skin cancer prevention behaviors (p < ۰.۰۰۱). Conclusion: The results showed that the structure of perceived self-efficacy and behavioral intention are the most effective factors on preventive behaviors of skin cancer. Therefore, it is recommended that in the field of development of educational interventions in the prevention of skin cancer, these structures should be considered more.
