Stress, mental health and depression at the workplace have emerged as common and significant problems. The effectiveness of a stress-management program at the workplace was investigated.
The effectiveness of a stress-management program was examined in workers at a highly stressful workplace using a randomized controlled trial. The 58 workers in the office were randomly assigned into a stress-management group (n = 28) and a control group (n = 30). The stress-management program included lectures on the perception of stress, measures to cope with it, stress-management recording sheets, and e-mail counseling. This program was based on the cognitive behavioral approach. The stress-management program was carried out for 3 months, and perceived work-related stress and psychological symptoms were evaluated using: General Health Questionnaire (GHQ)-30, Center for Epidemiologic Study for Depression (CES-D), the Questionnaire of Work-Related Stress and the Effort-Reward Imbalance Questionnaire. Twenty-one out of the 28 in the stress-management group and all in the control group were successfully followed up.
In the stress-management group, a significant improvement in the depressive symptoms was observed, compared with the control group in CES-D (p = 0.003 by two-tailed paired t-test, and p = 0.042 by repeated measure analysis of variance). In the multiple regression analysis, the effect of stress management on depressive symptoms at follow-up was significant (p = 0.041), controlling for potential confounding factors. However, the alleviation of perceived occupational stress was limited.
A stress-management program based on the cognitive behavioral approach at the workplace may have potential for the prevention of depression.
工作场所的压力、心理健康和抑郁已成为常见且严重的问题。本研究调查了一项工作场所压力管理项目的有效性。
采用随机对照试验，对处于高压力工作场所的员工进行压力管理项目有效性的研究。办公室的58名员工被随机分为压力管理组（n = 28）和对照组（n = 30）。压力管理项目包括关于压力认知、应对措施、压力管理记录单和电子邮件咨询的讲座。该项目基于认知行为方法。压力管理项目持续3个月，使用以下量表评估感知到的与工作相关的压力和心理症状：一般健康问卷（GHQ）-30、流行病学研究中心抑郁量表（CES-D）、工作相关压力问卷和付出-回报失衡问卷。压力管理组的28名员工中有21名以及对照组的所有员工均成功完成随访。
在CES-D量表中，与对照组相比，压力管理组的抑郁症状有显著改善（双尾配对t检验p = 0.003，重复测量方差分析p = 0.042）。在多元回归分析中，控制潜在混杂因素后，压力管理对随访时抑郁症状的影响显著（p = 0.041）。然而，感知到的职业压力缓解有限。
基于认知行为方法的工作场所压力管理项目可能具有预防抑郁的潜力。
