Convergent validity.

The school students are facing mental health issues, and their performance is not improving in China. Health education policies are not implemented at the school level in China. However, scholars focus on college students’ health education, but the school student is neglected. The research’s primary objective is to answer the question: What is the impact of health education on the psychological well-being of school students? A sample of 549 10th grade students is collected from China’s public and private sector institutes. The partial least square–structural equation modelling (PLS-SEM) is employed to analyze the data. The outcomes highlighted that the impact of health education is significant on the psychological well-being of school students in China. Furthermore, the study introduced that the moderating role of sustainable health exercise and sports participation is critical as it positively influences the relationship between health education and psychological wellbeing. This research improves literature as the novel contribution are highlighted in theory. Furthermore, the government education policies must be reframed under the light of this research’ findings to improve students’ health.在中国，在校学生正面临心理健康问题，且表现未得到改善。国内校园层面尚未落实健康教育相关政策。然而现有研究多聚焦于大学生健康教育，却忽视了中小学生群体。本研究的核心目标旨在解答如下问题：健康教育对中国在校学生的心理健康福祉存在何种影响？研究从中国公办与民办院校中招募了549名十年级学生作为研究样本。本研究采用偏最小二乘结构方程模型（partial least square–structural equation modelling, PLS-SEM）对采集的数据进行分析。研究结果显示，健康教育对中国在校学生的心理健康福祉具有显著影响。此外，本研究证实，可持续健康锻炼与体育参与的调节作用至关重要，其可正向强化健康教育与心理健康福祉之间的关联。本研究在理论层面作出了创新性贡献，丰富了该领域的研究文献。基于本研究的结论，政府应重新调整现行教育政策，以提升学生的健康水平。
