Abstract The Coping With Strain (CWS) course is a modified version of the Coping With Depression (CWD) course. CWD has been shown to reduce depression in several target groups. However, no other study has tested a modified CWD course delivered at the workplace to promote mental health. As mental health problems among employees remain a neglected area in many countries, and initiatives at the workplace often lack documentation of effects, we tested the effects of CWS on self-esteem, self-efficacy and vitality. After advertisement at workplaces, 119 employees were randomized into Intervention Group 1 (IG1), which immediately participated in CWS, or Intervention Group 2 (IG2), which functioned as a control group for six months until its participation in CWS. The follow-up period lasted for four years in both IG1 and IG2. Linear mixed models were fitted to the data. Self-efficacy, self-esteem and vitality increased significantly during the course and showed further significantly elevated levels at the follow-ups. CWS delivered at the workplace has short-term effects and the long-term effects may be maintained over a period of four years.

应对应变（CWS）课程对员工的积极心理健康影响：一项为期四年的纵向随机对照试验

摘要应对压力（CWS）课程是应对抑郁（CWD）课程的修订版。已证明CWD可以减少几个目标人群的抑郁症。但是，没有其他研究对在工作场所提供的改进的CWD课程进行测试，以促进心理健康。由于在许多国家/地区，员工的心理健康问题仍然是一个被忽视的领域，并且工作场所的举措经常缺乏影响的文件，因此我们测试了CWS对自尊，自我效能和活力的影响。在工作场所刊登广告后，将119名员工随机分为立即参加CWS的干预小组1（IG1）或作为对照组的六个月的干预小组2（IG2），直到参加CWS。IG1和IG2的随访期均为四年。将线性混合模型拟合到数据。在整个过程中，自我效能感，自尊心和活力显着提高，并在随访中显示出更高的水平。在工作场所交付的标准煤具有短期影响，长期影响可维持四年。
