doi: http://dx.doi.org/        Considering the prevalence of cell phone usage among young people, especially university students, it is crucial to pay attention to the microbial and radiation effects of cell phones. Therefore, the current research was conducted with the aim of predicting the intention and behavior of preventing microbial complications and cell phone radiation using the theory of planned behavior. The present study was based on an applied methodology and a descriptive approach. The research was conducted on a representative sample of students at Shahid Chamran University of Ahvaz. A total of 292 participants were selected using the convenience sampling method. The data was collected using the Planned Behavior Theory Questionnaire for preventive behaviors regarding microbial complications and cell phone radiation (babaei hyderabadi et al., 2020). Among the components of the theory of planned behavior, attitude and perceived behavioral control had a significant relationship with the intention to prevent microbial complications and cell phone radiation. Also, the intention of preventive behavior and perceived behavioral control can predict the behavior of preventing complications and cell phone radiation. Since attitude had the greatest effect on the intention to prevent microbial complications and cell phone radiation, and behavioral intention could predict the most amount of behavior to prevent microbial complications and cell phone radiation. Therefore, the theory of planned behavior can be a suitable framework for predicting the intention and behavior of preventing microbial complications and cell phone radiation in students.
