A study of the mediating role of bedtime music in employment anxiety and sleep quality among college students DATA.xl

Abstract: Objective: This study aims to investigate the prevalence of employment-related stress and sleep disturbances among contemporary college students. Furthermore, it seeks to examine the mediating influence of bedtime music on the employment and sleep quality of college students.Methods: A total of 1265 subjects were randomly selected for this research. The primary research instruments included the independent variable "Zhang Yuzhu Career Anxiety Questionnaire for College Graduates," the dependent variable "Pittsburgh Sleep Quality Index Questionnaire," and the self-administered "Bedtime Music Self-Assessment Scale" as mediator variables. Data analysis was conducted using SPSS 26.0 software to examine the relationships between variables. Structural equation modeling was performed using SPSS 26.0 AMOS, along with multilevel linear regression analysis to validate the mediating effect.Results: The Amos analysis revealed that employment anxiety exerted a direct effect of 21.333 an indirect effect of 8, and a total effect of 24 on sleep quality, all of which were statistically significant, substantiating a noteworthy partial mediating effect. Linear regression analysis demonstrated a significant influence of employment anxiety on sleep quality (β = 0.583; T = 25.717; P < 0.001). Notably, when accounting for the presence of bedtime music in the regression analysis, the significant effect of employment anxiety on sleep quality diminished. Specifically, β decreased from 0.583 to 0.53, and T decreased from 25.717 to 22.91 Nevertheless, employment anxiety still exhibited a substantial impact on sleep quality (β = 0.53; T = 22.91; P < 0.001).Conclusion: This study concludes that employment-related anxiety has a positive and significant effect on sleep quality. Additionally, bedtime music exerts a negative and substantial influence on both employment anxiety and sleep quality. It also plays a partially mediating role in the relationship between employment anxiety and sleep quality among college students. This suggests that incorporating pre-sleep music can be an effective strategy for ameliorating sleep disturbances in college students experiencing employment-related anxiety.

摘要：
研究目的：本研究旨在探讨当代大学生就业相关压力与睡眠障碍的流行现状，并分析睡前音乐在大学生就业焦虑与睡眠质量之间的中介影响。
研究方法：本研究共随机选取1265名研究对象。主要研究工具包括：自变量为《张玉柱大学毕业生职业焦虑问卷》，因变量为《匹兹堡睡眠质量指数量表（Pittsburgh Sleep Quality Index）》，中介变量为自编《睡前音乐自我评估量表》。数据分析采用SPSS 26.0软件探究变量间关联；同时通过SPSS 26.0 AMOS构建结构方程模型，并结合多层线性回归分析验证中介效应。
研究结果：AMOS分析结果显示，就业焦虑对睡眠质量的直接效应为21.333，间接效应为8，总效应为24，各项效应均具有统计学显著性，证实存在显著的部分中介效应。线性回归分析表明，就业焦虑对睡眠质量具有显著正向影响（β=0.583；T=25.717；P<0.001）。值得注意的是，在回归模型中纳入睡前音乐变量后，就业焦虑对睡眠质量的影响效应有所减弱：β值从0.583降至0.53，T值从25.717降至22.91，但就业焦虑仍对睡眠质量存在显著影响（β=0.53；T=22.91；P<0.001）。
研究结论：本研究证实，就业相关焦虑对睡眠质量具有显著正向影响；睡前音乐对就业焦虑与睡眠质量均存在显著负向影响，并在大学生就业焦虑与睡眠质量的关联中发挥部分中介作用。这提示，睡前聆听音乐可作为缓解就业焦虑大学生睡眠障碍的有效干预策略。
