Abstract
Introduction: Students' health behavior is of great importance, as it has a direct impact on their physical and mental health, academic performance, and social interactions. The main objective of the present study is to develop a model of the relationship between health behaviors and students' personality characteristics, with the mediating role of physical activity among female high school students in Tehran.
 
Methods: The present study is a descriptive survey research based on its purpose, application and data collection, which was conducted in a field manner. The statistical population of this study is all female high school students (about 6 million people) in the academic year 1402-1403. This research is an applied field study with the correlation method and structural equation modeling (PLS-SEM) which was conducted with a cluster sampling of 345 students and the data were analyzed with descriptive statistics (mean, standard deviation) and inferential statistics including confirmatory factor analysis and path analysis in SPSS and SmartPLS software.
Results: Health behaviors have a negative and significant effect on the consequences of personality traits (P < 0.05). The results of the study showed that health behaviors have a positive and significant effect on physical activity (P < 0.05).
Conclusion: Physical activity has a mediating role, the increase of which increases the intensity of the relationship between health behaviors and the consequences of personality traits.
