睡前高觉醒在军校大学生睡前使用手机与睡眠质量的中介效应

目的 调查睡前觉醒程度在军校学员睡前使用手机与睡眠质量间的中介效应。方法 采整群抽样方法,使用自编人口学问卷、匹兹堡睡眠量表(PSQI)和睡前觉醒量表(PSAS)对军校学员进行调查。采用Pearson相关分析、中介效应分析和Bootstrap检验方法进行分析。结果 (1)相关分析显示,睡前使用手机与PSQI总分之间呈正相关(r=0.251,p<0.01), 睡前觉醒程度与PSQI总分之间呈正相关(r=0.507,p<0.01),睡前使用手机与睡前觉醒程度呈正相关(r=0.239,p<0.01)(2)模型各路径系数有统计学意义(p<0.05),各拟合指标均较好。睡前使用手机对睡眠的中介效应为0.139,中介效应占总效应的45.3%。结论 睡前高觉醒在军校学员的睡前使用手机与睡眠状况的关系中起部分中介的作用。

Mediating effect of pre-sleep hyperarousal between bedtime mobile phone use and sleep among military university students

Objective: To investigate the mediating effect of pre-sleep hyperarousal between bedtime mobile phone use and sleep among military university students. Methods: Military university students were investigated by self-designed demographic questionnaire, the Pittsburgh sleep scale (PSQI) and the pre-sleep arousal scale (PSAS). Pearson correlation analysis, mediation effect analysis and Bootstrap test were used for analysis. Results: (1) Pearson correlation analysis showed that there was a positive correlation between bedtime mobile phone use and sleep quality (r=0.251, p<0.01). There was a positive correlation between pre-sleep arousal and sleep quality(r=0.507,p<0.01). And bedtime mobile phone use was associated with pre-sleep arousal (r=0.239, p<0.01); (2) the path coefficients of the model were statistically significant (p<0.05), and all fitting indexes were good. The mediating effect of bedtime mobile phone use on sleep quality was 0.139, accounting for 45.3% of the total effect. Conclusion: Pre-sleep arousal play a mediating role in the relationship between bedtime mobile phone use and sleep quality among military university students.
