在数字技术深度渗透青少年日常生活的背景下，中国青少年网络成瘾问题已从个体行为异常演变为影响社会稳定的公共健康挑战。因网络成瘾引发的学业中断、家庭冲突及极端事件呈持续增长态势，这一现实困境倒逼学术界通过诊断标准的范式转型，构建科学有效的防控体系。系统梳理中国青少年网络成瘾诊断标准自"行为描述"经"功能评估"到"临床操作"的"三阶进化"路径，不仅揭示了青少年网络成瘾诊断标准从经验性探索走向科学化建构的内在规律，还为破解当前中国青少年网络成瘾诊断实践中的技术适配、文化兼容等核心难题提供了历史镜鉴，最终为构建"动态化、精准化、文化适配化"的诊断标准体系夯实了理论与实践基础。

Against the backdrop of digital technology deeply permeating into the daily lives of adolescents, the issue of internet addiction among Chinese adolescents has evolved from individual behavioral abnormalities into a public health challenge that affects social stability. The continuous growth of school dropouts, family conflicts, and extreme incidents triggered by internet addiction has compelled academia and policymakers to construct a scientific and effective prevention and control system through the paradigm transformation of diagnostic criteria. By systematically reviewing the " three-stage evolution" path of diagnostic criteria for internet addiction among Chinese adolescents, from " behavioral description" to " functional assessment" and then to " clinical operation" , this study not only reveals the inherent laws underlying the transition from empirical exploration to scientific construction of these criteria, but also provides historical lessons for addressing core challenges such as technological adaptability and cultural compatibility in current diagnostic practices for internet addiction among Chinese adolescents. Ultimately, it lays a solid theoretical and practical foundation for building a " dynamic, precise, and culturally adapted" diagnostic criteria system.
