背景和目的：与失眠相关的高风险心理社会工作特征的细节尚不清楚，尽管已经提出了两者之间的潜在关系。本研究的目的是利用需求-控制-支持(DCS)模型和努力-回报不平衡(ERI)模型来阐明这些关系。研究对象和方法：对日本大阪一家电子产品企业集团的1081名中年(39岁及以上)员工进行横断面问卷调查。研究变量包括失眠症状(不清新的睡眠、入睡困难、频繁的睡眠干扰和清晨唤醒)和心理社会工作特征，并使用DCS和ERI模型进行评估，性别、年龄、疾病、睡眠相关因素、职业状况和健康实践。结果：ERI[优势比(95%可信区间)：2.27(1.43，3.60)]、过度承诺[1.86(1.40，2.47)]和高工作紧张[1.55(1.12，2.15)]与失眠独立相关。工作压力大的个体发生失眠的优势比随着工作压力的增加而增加。结论：ERI和DCS模型描述了与失眠相关的不良心理社会工作特征。同时使用这两种模型比使用单一模型来识别有失眠风险的员工更有用。从工作压力模型得出的概念框架有助于确定工人失眠的预防措施。(C)2005 Elsevier B.V.保留所有权利。
Background and purpose: The details of risky psychosocial job characteristics related to insomnia are unclear, although potential relationships between the two have been suggested. The study objective was to clarify these relationships by using the demand-control-support (DCS) model and the effort-reward imbalance (ERI) model.Patients and methods: A cross-sectional questionnaire survey was conducted with 1081 middle-aged (39 years and older) workers in a corporate group of electric products in Osaka, Japan. The study variables included insomnia symptoms (non-refreshing sleep, difficulty falling asleep, frequent sleep disruption, and early morning arousal) and psychosocial job characteristics which were evaluated using the DCS and ERI models, gender, age, disease, sleep-related factors, occupational status, and health practices.Results: ERI [odds ratio (95% confidence interval): 2.27 (1.43, 3.60)], overcommitment [1.86 (1.40, 2.47)], and high job strain [1.55 (1.12, 2.15)] were independently associated with insomnia. The odds ratio of insomnia for individuals with high job strain was increased by adding ERI or overcommitment.Conclusions: The ERI and DCS models describe the adverse psychosocial job characteristics related to insomnia. Simultaneously employing these two models is more useful than employing a single model to identify workers at risk of insomnia. The conceptual framework derived from the job stress models assists in defining preventive measures for insomnia in workers. (c) 2005 Elsevier B.V. All rights reserved.
