Abstract

Background: To explore the mediating effect of smartphone addiction between psychological resilience and insomnia among university students.

Methods: This study included 581 clinical medical students from the Dalian Medical University, enrolled between September 2020 and May 2023. The Smartphone Addiction Scale (SAS-SV), Insomnia Severity Index (ISI), and Connor-Davidson Resilience Scale (CD-RISC) were used to assess smartphone addiction, insomnia, and psychological resilience among the students. The Process macro and Bootstrap methods were employed to analyze the mediating effect of smartphone addiction between psychological resilience and insomnia.

Results: The detection rate of smartphone addiction was 28.06% (163/581), and the detection rate of insomnia was 26.17% (152/581). The total SAS-SV score was 27.60 ± 14.27, the total ISI score was 6.60 ± 5.33, and the total CD-RISC score was 72.86 ± 6.88. There was a significant negative correlation between the total CD-RISC score and the total SAS-SV score (r = -0.4129, P < .0001), and a significant negative correlation between the total CD-RISC score and the total ISI score (r = -2.942, P < .0001). The total SAS-SV score and the total ISI score were significantly positively correlated (r = 0.5687, P < .0001). Psychological resilience was used as the independent variable, insomnia as the dependent variable, and smartphone addiction as the mediating variable in the mediation effect analysis. Psychological resilience negatively predicted insomnia (β = -0.0940, P < .0001), smartphone addiction positively predicted insomnia (β = 0.1564, P < .0001), and smartphone addiction mediated the relationship between psychological resilience and insomnia (effect value = -0.1339, 95% CI: -0.1680 to -0.1034), with an effect size of 58.75%.

Conclusion: Psychological resilience directly affects insomnia and also indirectly affects insomnia through the mediating effect of smartphone addiction.

智能手机成瘾在医学生心理复原力与失眠之间的中介作用。

背景：探讨智能手机成瘾与大学生失眠之间的中介效应：目的：探讨智能手机成瘾在大学生心理复原力和失眠之间的中介效应：本研究纳入了大连医科大学 581 名临床医学专业学生，入学时间为 2020 年 9 月至 2023 年 5 月。采用智能手机成瘾量表（SAS-SV）、失眠严重程度指数（ISI）和康纳-戴维森复原力量表（CD-RISC）对学生的智能手机成瘾、失眠和心理复原力进行评估。采用过程宏法和Bootstrap法分析智能手机成瘾在心理复原力和失眠之间的中介效应：智能手机成瘾检出率为 28.06%（163/581），失眠检出率为 26.17%（152/581）。SAS-SV总分为（27.60 ± 14.27）分，ISI总分为（6.60 ± 5.33）分，CD-RISC总分为（72.86 ± 6.88）分。CD-RISC 总分与 SAS-SV 总分呈显著负相关（r = -0.4129，P < .0001），CD-RISC 总分与 ISI 总分呈显著负相关（r = -2.942，P < .0001）。SAS-SV 总分与 ISI 总分呈显著正相关（r = 0.5687，P < .0001）。在中介效应分析中，心理复原力作为自变量，失眠作为因变量，智能手机成瘾作为中介变量。心理复原力对失眠有负向预测作用（β = -0.0940，P < .0001），智能手机成瘾对失眠有正向预测作用（β = 0.1564，P < .0001），智能手机成瘾对心理复原力和失眠之间的关系有中介作用（效应值 = -0.1339，95% CI：-0.1680 至 -0.1034），效应大小为 58.75%：结论：心理复原力直接影响失眠，并通过智能手机成瘾的中介效应间接影响失眠。
