摘要

目的

对实习护生的昼夜节律类型、睡眠质量与工作沉浸的现状进行调查，并探讨昼夜节律类型和睡眠质量对工作沉浸的作用路径。

方法

通过便利抽样法，在2024年12月至2025年2月期间，选取来自甘肃省5所本科院校且在兰州市3所三级甲等教学医院实习的300名护生作为研究对象。采用一般资料问卷、昼夜节律类型量表、简化版工作沉浸量表及匹兹堡睡眠质量指数（Pittsburgh sleep quality index，PSQI）作为研究工具开展调查。运用SPSS 28.0软件对实习护生的一般资料、昼夜节律类型、PSQI评分和工作沉浸得分进行描述性分析与Spearman相关性分析；运用Amos 27.0软件进行中介效应分析，通过极大似然法对模型进行拟合，构建昼夜节律类型、睡眠质量与工作沉浸之间的结构方程模型。

结果

实习护生工作沉浸得分为42（28，54）；昼夜节律类型的灵活性/刚性分量表得分为18.22±5.51，困倦/活力分量表得分为16.53±6.58；灵活性型和活力型所占比例分别为48.62%（141/290）和24.14%（70/290）。PSQI得分为7（5，14），存在睡眠问题的实习护士占比为64.14%（186/290）。路径分析显示，实习护生的昼夜节律类型在睡眠质量与工作沉浸之间起部分中介作用，灵活性/刚性和困倦/活力的中介效应分别为-1.084和-2.244，分别占总效应的29.66%和61.39%，总间接效应占总效应的91.05%。

结论

实习护生的昼夜节律类型是睡眠质量与工作沉浸的中介变量。未来护理实习管理者应注重改善实习护生的睡眠质量，通过合理排班、优化环境、开展心理调节等综合措施，促使护生调节自身昼夜节律类型，使其尽快从夜班轮值状态中恢复，提升实习护生的工作沉浸水平。

Abstract

Objective

To investigate the current status of circadian rhythm type

sleep quality

and work immersion among nursing interns

and to explore the pathway through which circadian rhythm type and sleep quality influence work immersion.

Methods

A convenience sampling method was used to select 300 nursing interns from five undergraduate universities in Gansu Province who were interning at three Grade A tertiary teaching hospitals in Lanzhou from December 2024 to February 2025. A general information questionnaire

the Circadian Rhythm Type Scale

the Simplified Work Immersion Scale

and the Pittsburgh sleep quality index (PSQI) were used as research instruments. SPSS 28.0 software was used for descriptive analysis and Spearman correlation analysis of the general information

circadian rhythm types

PSQI scores

and work immersion scores of nursing interns. Amos 27.0 software was used for mediating effect analysis. A structural equation model was constructed between circadian rhythm type

sleep quality

and work immersion by fitting the model using the maximum likelihood method.

Results

The work immersion score for nursing interns was 42 (28

54). The score for the Flexibility/Rigidity Subscale of Circadian Rhythm Type Scale was 18.22±5.51

and the score for the Languid/Vigorous Subscale was 16.53±6.58. The proportions of flexible and vigorous types were 48.62% (141/290) and 24.14% (70/290)

respectively. The PSQI score was 7 (5

14)

and 64.14% (186/290) of nursing interns experienced sleep problems. Pathway analysis revealed that circadian rhythm type partially mediated the relationship between sleep quality and work immersion in nursing interns. The mediating effects of flexibility/rigidity and languid/vigorous types were -1.084 and -2.244

accounting for 29.66% and 61.39% of the total effect

respectively. The total indirect effect accounted for 91.05% of the total effect.

Conclusions

The circadian rhythm type of nursing interns is a mediating variable between sleep quality and work immersion. In the future

nursing internship managers should focus on improving the sleep quality of nursing interns through comprehensive measures such as reasonable shift scheduling

environmental optimization

and psychological adjustment. This will help nursing interns adjust their circadian rhythm type

recover promptly from night shift work

and enhance their level of work immersion.
