摘要目的:从变量中心和个体中心的角度，探究问题性手机使用与人际关系困扰、抑郁、睡眠质量间的关系。方法:2021年12月至2022年1月，采用手机成瘾指数量表、人际关系综合诊断量表、流调中心用抑郁量表、匹兹堡睡眠质量指数对851名中学生进行调查。运用SPSS 26.0统计软件进行共同方法偏差检验、描述统计、相关分析，采用Mplus 8.8构建结构方程模型，进行潜在剖面分析。结果:问题性手机使用得分(47.23±14.50)分，人际关系困扰得分(8.72±5.68)分，抑郁得分(14.80±10.28)分，睡眠质量得分(5.51±2.78)分。变量中心方面，问题性手机使用对睡眠质量直接效应显著(效应值为0.22，95% CI＝0.11~0.34)，占总效应的40.74%；抑郁在问题性手机使用和睡眠质量间存在中介效应(效应值为0.08，95% CI＝0.03~0.14)，占总效应的14.81%；人际关系困扰-抑郁在问题性手机使用和睡眠质量间具有链式中介效应(效应值为0.22，95% CI＝0.16~0.30)，占总效应的40.74%(0.22/0.54)。个体中心方面，青少年问题性手机使用分为轻度使用组(26.1%)、中度使用组(54.7%)和重度使用组(19.2%)3个潜在类别，抑郁(中度使用组：效应值＝0.05，95% CI＝0.02~0.12；重度使用组：效应值＝0.07，95% CI＝0.02~0.10)和人际关系困扰-抑郁(中度使用组：效应值＝0.13，95% CI＝0.09~0.18；重度使用组：效应值＝0.21，95% CI＝0.15~0.28)在问题性手机使用剖面与睡眠质量间的相对中介效应显著。 结论:青少年问题性手机使用存在异质性，变量中心和个体中心的结果均表明抑郁和人际关系困扰-抑郁中介了青少年问题性手机使用对睡眠质量的影响。

abstractsObjective:To explore relationships between problematic mobile phone use and interpersonal distress, depression and sleep quality using a combined variable- and person-centered approach.Methods:From December 2021 to January 2022, a total of 851 middle school students were measured by the mobile phone addiction index scale, the college students interpersonal comprehensive diagnostic scale, the center for epidemiologic studies depression scale, and the Chinese version of Pittsburg sleep quality index. Common method bias test, descriptive statistics, and correlation analysis were performed using SPSS 26.0 statistical software, and Mplus 8.8 software was used to construct structural equation models for latent profile analysis.Results:The score of problematic mobile phone use was(47.23±14.50), the score of interpersonal distress was(8.72±5.68), the score of depression was(14.80±10.28), the score of sleep quality was(5.51±2.78). Variable-centered analysis revealed that problematic mobile phone use had a significant direct effect on sleep quality (effect value=0.22, 95% CI=0.11-0.34), accounting for 40.74% of the total effect. The mediating effect of depression was found between problematic mobile phone use and sleep quality (effect value=0.08, 95% CI=0.03-0.14), accounting for 14.81% of the total effect. Interpersonal distress and depression had a chain mediating effect between problematic mobile phone use and sleep quality(effect value=0.22, 95% CI=0.16-0.30), accounting for 40.74%(0.22/0.54) of the total effect. Person-centered analysis revealed that problematic mobile phone use was divided into three potential profiles: mild use group(26.1%), moderate use group(54.7%) and severe use group(19.2%). Depression(moderate use group: effect size=0.05, 95% CI=0.02-0.10; severe use group: effect size=0.07, 95% CI=0.02-0.12) and interpersonal distress-depression(moderate use group: effect size=0.13, 95% CI=0.09-0.18; severe use group: effect size=0.21, 95% CI=0.15-0.28) had a significant relative mediating effect between problematic mobile phone use profiles and sleep quality. Conclusion:Adolescent problematic mobile phone use is heterogeneous, with both variable-centered and person-centered results indicating that depression and interpersonal distress-depression mediated the effects of adolescent problematic mobile phone use on sleep quality.
