Moderating effect of sleep quality on the relationship between problematic mobile phone use and anxiety of college students

Abstract

Objective To describe the prevalence of problematic mobile phone use and anxiety in college students, and explore the mediating effect of sleep quality on the relationship between problematic mobile phone use and anxiety, and to provide reference for physical and mental health promotion of college students. Methods One medical college and a comprephensive college were selected in Hefei city of Anhui Province and Shangrao City of Jiangxi Province, respectively, and a cross-sectional survey was conducted. A total of 1 135 valid questionnaires were collected. The self-rating questionnaires regarding basic information of college students, use the Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use(SQAPMPU) and the Self-Rating Questionnaire for Depression-Anxiety-Stress for Adolescent Problematic Mobile Phone Use (DASS-21) was used to evaluate problematic mobile phone use and anxiety, respectively. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Results The detection rates of college students with problematic mobile phone use and poor sleep quality were 24.6% and 13.3%, respectively. The detection rates of college students anxiety grouped by severity were 5.1%, 23.9%. Multiple Logistic regression analysis showed a positive linear correlation between problematic mobile phone use and anxiety [ OR values (95% CI ) were 1.86 (1.01-3.44), 4.34(3.14-5.99), P <0.01] . The results of process showed that sleep quality played a moderating role between problematic mobile phone use and anxiety ( R 2 = 0. 37, F = 220.52, P <0.01). Interaction term’s β = 0.09 ( P <0.05). Conclusion The prevalence of problematic mobile phone use is high in college students, and problematic mobile phone use is positively related to anxiety. Good sleep quality can alleviate the relationship between mobile phone dependence and anxiety of college students. 【摘要】 目的 描述大学生手机依赖与焦虑的流行状况及其与焦虑间的调节效应, 为促进大学生群体身心健康发展提供 参考。 方法 使用横断面调査方法, 在安徽省合肥市和江西省上饶市分别选取 1 所医科类院校及 1 所综合类院校, 共调査 1 135 名大学生, 使用青少年手机使用依赖自评问卷、抑郁-焦虑-压力自评量表分别评估大学生手机依赖和焦虑, 运用匹 兹堡睡眠质量指数量表评估大学生睡眠质量。 结果 大学生手机依赖和睡眠质量差的检出率分别为 24.6% 和 13.3%, 轻度 和中度及以上焦虑的检出率分别为 5.1% 和 23.9%。多元Logistic回归分析显示, 手机依赖与轻度焦虑、中度及以上焦虑呈 正相关 [ OR 值 (95% CI )分别为 1.86(1.01~3.44), 4.34 (3.14 ~ 5.99), P 值均<0.01]。调节效应分析结果显示, 睡眠质量在 手机依赖与焦虑间起调节作用 ( R 2 = 0.37, F = 220.52, P <0.01);交互项“手机依赖x睡眠质量”的回归系数为 0.09 ( P <0.05)。 结论 大学生手机依赖报告率髙, 手机依赖与焦虑呈正向关联, 良好的睡眠质量可缓解手机依赖对大学生焦虑的预测 作用。
