本研究旨在探讨两个人格变量（消极情感[NA]和积极情感[PA]）和三个工作相关的压力源（人际冲突、工作量和知觉模糊）对睡眠质量的多维度测量（上床睡觉、入睡、保持睡眠、重新启动睡眠和醒来）的影响。347名女大学生和120名男大学生参与了这项研究。结果表明：（a）NA高的个体比NA低的个体睡眠质量更差;（B）PA高的个体比PA低的个体睡眠质量更高;（c）睡眠质量与人际冲突、工作要求和工作模糊性呈负相关; NA调节了人际冲突与睡眠质量之间的关系以及知觉模糊与睡眠质量之间的关系。我们的研究结果首次表明，个性和工作压力会影响睡眠质量的不同方面。此外，我们的研究结果是部分支持的超反应的作用，消极的情感，这表明，NA操作放大个人的看法和反应的负面环境事件。然而，我们的研究结果表明，超响应模型可能比以前指出的更复杂。(c)2006爱思唯尔有限公司保留所有权利。
This study was designed to examine the influence of two personality variables (negative affectivity [NA] and positive affectivity [PA]) and three work-related stressors (interpersonal conflict, workload, and perceived ambiguity) on a multi-dimensional measure of sleep quality (going to bed, falling asleep, maintaining sleep, reinitiating sleep, and waking up). Three hundred and forty-seven female and 120 male undergraduates participated in the study. Our results indicated that (a) individuals high in NA tended to report lower quality sleep than individuals low in NA; (b) individuals high in PA tended to report higher levels of sleep quality than individuals low in PA; (c) sleep quality tended to relate negatively with interpersonal conflict, work demands, and job ambiguity; and (d) NA moderated the relationships between interpersonal conflict and sleep quality and between perceived ambiguity and sleep quality. Our findings are the first to show that personality and work-related stress influences different aspects of sleep quality. In addition, our findings are partially supportive of the hyper-responsivity role of negative affectivity which suggests that NA operates to amplify individuals' perceptions of and reactions to negative environmental events. However, our results suggest that the hyper-responsivity model might be more complex than previously indicated. (c) 2006 Elsevier Ltd. All rights reserved.
