• Abstract: The Internet is deeply integrated into the lives of youth, and issues related to Internet overindulgence have grown increasingly prominent. Understanding the underlying mechanisms of this phenomenon is crucial for developing effective intervention strategies. This study surveyed 4235 junior and secondary high school students and integrated the model of compensatory internet use, the Limited Strength Model of Self-control, and the Psychological Decompensation Hypothesis to construct a chain mediation model. The model was used to examine the impact of academic stress on youth Internet overindulgence, as well as the roles of self-control and loneliness in this relationship. Data were collected via questionnaires and analyzed using structural equation modeling (SEM). The results indicated that academic stress was a significant positive predictor of Internet overindulgence. Self-control and loneliness each played mediating roles in the relationship between academic stress and Internet overindulgence. More importantly, a significant chain mediation pathway was identified, following the sequence of “academic stress-self-control-loneliness-Internet overindulgence.” This study reveals a “psychological resource-emotional compensation” two-stage mechanism through which stress influences Internet overindulgence among youth, offering a new theoretical foundation and practical insights for understanding this issue. 随着互联网在未成年人生活中的深度渗透，未成年人网络沉迷问题愈发严峻，探究其形成机制对制定更加有效的干预策略意义重大。本研究以4235名初高中学生为研究对象，整合补偿性网络使用模型、有限自制力原理与“失补偿”假说，构建链式中介模型，旨在考察学业压力对青少年网络沉迷的影响，以及自我控制和孤独感在其中的作用。研究采用问卷调查法，并通过结构方程模型进行分析。结果显示，学业压力能显著正向预测青少年网络沉迷；自我控制与孤独感分别在学业压力与网络沉迷间起中介作用。更重要的是，自我控制与孤独感在学业压力与网络沉迷之间形成“学业压力—自我控制—孤独感—网络沉迷”的显著链式中介路径。本研究揭示了学业压力影响未成年人网络沉迷的心理资源与情感补偿双阶段机制，为理解和干预未成年人网络沉迷提供了新的理论依据与实践启示。
