生活节奏在本科护生手机成瘾与睡眠质量间的中介效应

Mediation effect analysis of social rhythm of undergraduate nursing students between mobile phone addiction andsleep quality

目的 了解本科护生睡眠质量与手机成瘾、生活节奏的现状及相关性,并探讨生活节奏在本科护生手机成瘾与睡眠质量间的中介作用。方法 通过一般资料调查表、手机成瘾指数量表、生活节奏量表、匹兹堡睡眠质量指数量表对某医学院校2018—2021级的386名本科护生进行调查。结果 本科护生生活节奏总分(27.38±10.67)分;手机成瘾总分(36.71±15.73)分,手机成瘾检出率20.2%;睡眠质量得分(4.82±2.87)分,睡眠障碍检出率14.2%。本科护生的生活节奏(r=0.393)、手机成瘾(r=0.489)与睡眠质量间(r=0.460)存在显著的正相关关系(P<0.001)。在控制一般资料变量后,生活节奏在本科护生手机成瘾与睡眠质量间存在部分中介作用,中介效应值为0.124,占总效应的22.14%。结论 手机成瘾不仅可以直接影响睡眠质量,还可以通过生活节奏间接影响睡眠质量,护理教育人员应关注本科护生的生活节奏,改善其睡眠质量。

Objective To understand the current status and association between sleep quality,mobile phone addiction,and social rhythm among undergraduate nursing students,and explore the mediating role of social rhythm between mobile phone addiction and sleep quality of undergraduate nursing students.Methods A survey of 386 undergraduate nursing students from the 2018 to 2021 grades at a medical university was conducted by means of the general information questionnaire,Mobile Phone Addiction Index,the Brief Social Rhythm Scale,and Pittsburgh Sleep Quality Index.Results Undergraduate nursing students had a total score of(27.38±10.67)for social rhythm;a total score of(36.71±15.73)for mobile phone addiction,with a detection rate of 20.2%for mobile phone addiction;and a score of(4.82±2.87)for sleep quality,with a detection rate of 14.2%for sleep disorder.There was a positive correlation between the social rhythm,mobile phone addiction,and sleep quality of undergraduate nursing students(r=0.393,0.489,0.460,P<0.001).After controlling the demographic variables,social rhythm was a partial mediator between mobile phone addiction and sleep quality,with a mediation effect value of 0.124,accounting for 22.14%of the total effect.Conclusion Mobile phone addiction may affect sleep quality not only directly,but also indirectly through the social rhythm.Nursing educators should concentrate on the social rhythm of undergraduate nursing students to improve their sleep quality.
