Data Sheet 1_The relationship between physical exercise and academic burnout in adolescents: the chain-mediated role of internet addiction and self-control.pdf

BackgroundAcademic burnout represents a pressing issue among adolescents in China and has garnered increasing attention from scholars in the sport science domain. This study aims to investigate the underlying mechanisms linking physical exercise, internet addiction, self-control, and academic burnout, drawing on empirical survey data collected from adolescents in Shaanxi Province, China.
MethodsThis study employed a cross-sectional survey design, utilizing the Physical Activity Rating Scale (PARS-3), Chinese Internet Addiction Test (TAT), Self-Control Scale (SCS), and Academic Burnout Inventory (ABI) to collect data from 1,948 adolescents in Shaanxi Province (Mage = 13.74, SD = 1.37). Through descriptive analysis, we conducted statistical analyses on demographic variables. Utilizing Pearson correlation analysis, regression analysis, and chain mediation analysis, we constructed a relational model among variables.
ResultsThe findings revealed significant pairwise correlations among Physical Exercise, Self-Control, Internet Addiction, and adolescent Academic Burnout. Specifically: Physical Exercise positively predicted Self-Control but negatively predicted Internet Addiction and Academic Burnout. Self-Control negatively predicted Internet Addiction and Academic Burnout. Internet Addiction positively predicted Academic Burnout.
ConclusionSelf-Control and Internet Addiction independently mediated the relationship between Physical Exercise and adolescent Academic Burnout. Additionally, Self-Control and Internet Addiction jointly acted as chain mediators in this relationship.

研究背景 学术倦怠（Academic burnout）是中国青少年群体中亟待解决的突出问题，亦日益受到运动科学领域学者的广泛关注。本研究基于中国陕西省青少年的实证调研数据，旨在探讨体育运动、网络成瘾、自我控制与学术倦怠之间的内在作用机制。
研究方法 本研究采用横断面调查设计，运用运动活动评定量表（Physical Activity Rating Scale, PARS-3）、中文网络成瘾测验（Chinese Internet Addiction Test, TAT）、自我控制量表（Self-Control Scale, SCS）以及学术倦怠量表（Academic Burnout Inventory, ABI），对陕西省1948名青少年开展数据采集（平均年龄Mage=13.74，标准差SD=1.37）。首先对人口统计学变量进行描述性统计分析，随后通过皮尔逊相关分析、回归分析以及链式中介分析，构建各变量间的关系模型。
研究结果 结果显示，体育运动、自我控制、网络成瘾与青少年学术倦怠之间均存在显著的两两相关关系。具体如下：体育运动对自我控制具有正向预测作用，而对网络成瘾与学术倦怠则具有负向预测作用；自我控制对网络成瘾与学术倦怠具有负向预测作用；网络成瘾对学术倦怠具有正向预测作用。
研究结论 自我控制与网络成瘾分别在体育运动与青少年学术倦怠的关系中发挥中介作用；此外，二者亦共同作为链式中介变量参与该路径的传导过程。
