大学生焦虑受到诸多因素的影响，其中大学生的压力感知一直是研究的热点和堵点。为探索压力感知与大学生焦虑之间的关联及其内在作用机制，采用量表测量法对1 009名大学生进行调查分析，旨在建立压力感知、智能手机成瘾、失眠与大学生焦虑的关系模型。研究发现，压力感知与大学生焦虑关系密切，压力感知可通过智能手机成瘾→失眠的多重效应诱发大学生焦虑。这一研究结论在理论上有助于揭示压力感知对大学生焦虑影响的内在作用机制，丰富该领域的理论研究成果。在实践中，有助于提醒高校相关部门应积极关注压力感知对大学生焦虑的不良影响，群策群力，多方协同预防和干预大学生焦虑。

College students' anxiety is influenced by various factors, with stress perception being a prominent and challenging area of research. This study aims to explore the relationship between stress perception and college students' anxiety, as well as its underlying mechanisms. Using a survey method, data were collected from 1 009 college students to establish a model linking stress perception, smartphone addiction, insomnia, and anxiety. The findings indicate a strong correlation between stress perception and anxiety among college students. Specifically, stress perception can trigger anxiety through the sequential effects of smartphone addiction and insomnia. Theoretically, this study contributes to understanding the intrinsic mechanisms by which stress perception affects anxiety, enriching the theoretical framework in this field. Practically, it underscores the importance for college authorities to recognize the detrimental impact of stress perception on students忆 anxiety and to adopt a collaborative, multi-faceted approach to prevention and intervention.
