基金：We are deeply grateful to all the participants in this study. All authors confirm that the following manuscript is a transparent and honest account of the reported research. This research is related to a previous study by the same authors titled Development and validation of the Chinese family environment influencing physical activity Habits scale. The previous study was performed on understanding how family dynamics influence physical activity habits within the Chinese population and the current submission is focusing on the school environment, recognizing its pivotal role in shaping children's physical activity behaviors. The study is following the methodology explained in the following: we utilized Polit and Beck's (2006) framework for expert validity. For item analysis, we applied the methods of Raykov and Marcoulides (2011). Our approach to exploratory and confirmatory factor analysis was informed by the comprehensive guidelines of Costello and Osborne (2019) and Brown (2015). Data adequacy was verified using the Kaiser-Meyer-Olkin measure and Bartlett's test, as recommended by Kleinbaum (2013). We assessed reliability through Cronbach's alpha, following Tavakol and Dennick (2011), and evaluated structural validity using Composite Reliability (CR) and Average Variance Extracted (AVE). By relying on these authoritative sources, we ensured our methodology meets the highest research standards.

摘要：Introduction Regular physical activity is essential for preventing overweight and obesity in children and adolescents while also enhancing mental well-being. For teenagers, behaviors are predominantly shaped by habits, highlighting the importance of fostering positive physical activity practices. Schools, as central to adolescents' daily routines, play a critical role in influencing students' lifestyles and activity levels.Methods This study aimed to develop and validate a measurement instrument tailored to the Chinese social context to assess the impact of school-based factors on adolescents' physical activity habits. A sample of 1,061 students was recruited through stratified cluster sampling from 24 secondary schools across six provinces in China. Following data cleaning, 1,004 valid responses were analyzed. The sample was divided into two subsets: one (n = 502) for exploratory factor analysis (EFA) and one (n = 502) for confirmatory factor analysis (CFA).Results EFA identified four factors comprising 19 items: Facility Environment Attraction (5 items), Specification of Teachers' Competence (5 items), Influence of Peer Relationships (5 items), and Guarantee of Curriculum Setting (4 items). The factors demonstrated strong internal consistency (Cronbach's alpha: 0.841-0.895). CFA confirmed the scale's validity with an acceptable model fit (CMIN/DF = 3.888, TLI = 0.904, SRMR = 0.043, RMSEA = 0.046, GFI = 0.918). Additionally, the scale exhibited high internal consistency and test-retest reliability.Discussion This validated instrument provides researchers with a robust tool to evaluate school-related influences on physical activity habits among Chinese adolescents. The findings offer practical insights for promoting healthy behaviors, improving physical and mental health, and fostering holistic well-being in this population.
