The present study was undertaken to examine the relationship between quality of life in schools and the behaviors of bullies/victims in relation to the mediating role of self-esteem. A sample of 241 high school students was selected, within a correlational design, through the one-stage cluster sampling method, from Meybod City, Yazd Province, Iran. The Quality of Life Questionnaire in Schools (QLQS), the Rosenberg's Self-Esteem Scale (RSEE), and the Illinois Bully Scale (IUBS) were utilized in this study. The results indicate that the stated model has a goodness of fit index (GFI = 0.99 and root mean square error of approximation [RMSEA] = 0.06). The path analysis showed that the direct effects of the quality of life in schools on bullying and self-esteem are significant but not significantly on victimization. There was no significant effect of self-esteem on bullying, but a meaningful effect on victimization. Furthermore, the indirect effects on the quality of life in schools on bully/victims through self-esteem were significant.

伊朗学校样本中欺凌者和受害者的生活质量和行为：自尊的调节作用。

本研究旨在检验学校生活质量与欺凌/受害者行为之间的关系，以及自尊的中介作用。在相关设计中，通过一阶段整群抽样方法从伊朗亚兹德省梅博德市选择了 241 名高中生样本。本研究使用了学校生活质量问卷 (QLQS)、罗森伯格自尊量表 (RSEE) 和伊利诺伊欺凌量表 (IUBS)。结果表明，所述模型具有拟合优度指数（GFI = 0.99 和近似均方根误差 [RMSEA] = 0.06）。路径分析表明，学校生活质量对欺凌和自尊的直接影响是显着的，但对受害不显着。自尊对欺凌没有显着影响，但对受害有有意义的影响。此外，自尊对欺凌/受害者的学校生活质量的间接影响是显着的。
