Aims: Throughout the ongoing COVID-۱۹ pandemic, the role of students in transmitting the infection has received special attention aiming at protecting the younger generation against COVID-۱۹ and other known respiratory diseases. This research aimed to specify factors related to Covid-۱۹ preventing behaviors in high school students. Instrument & Methods: This cross-sectional study was conducted on ۲۸۵۲ students aged ۱۳ to ۱۸ in Hamadan in ۲۰۲۰. Participants were selected using the multistage cluster sampling method. The data were collected with a researcher-made EPPM questionnaire. Data were analyzed statistically by Stata ۱۴.۲ software using the Chi-square and Fisherchr('۳۹')s exact tests. Findings: The vast majority of students (۶۷.۰۲%) were in the danger control response phase. The response efficacy (۷۷.۳%) and perceived efficacy (۷۵.۳%) had the highest percentage of the mean from the maximum obtainable score among constructs of the model. There was a significant difference between categories of the EPPM model with doing healthy behaviors. Moreover, the proportion of doing health behaviors was significantly higher in students in the danger control phase. Conclusion: The predominance of the perceived threat of COVID-۱۹ on the perceived efficacy affects preventive health behaviors. Therefore, a theory-based behavioral modification program can be developed based on gender among high school students. Higher grade students and poor socioeconomic status require intense educational interventions to modify their hygienic behaviors.
