Effectiveness of a Worksite Mindfulness-Related Multi-Component Health Promotion Intervention on Work Engagement and Mental Health: Results of a Randomized Controlled Trial

ObjectivesThe aim of the present study was to evaluate the effectiveness of a worksite mindfulness-related multi-component health promotion intervention on work engagement, mental health, need for recovery and mindfulness.MethodsIn a randomized controlled trial design, 257 workers of two research institutes participated. The intervention group (n = 129) received a targeted mindfulness-related training, followed by e-coaching. The total duration of the intervention was 6 months. Data on work engagement, mental health, need for recovery and mindfulness were collected using questionnaires at baseline and after 6 and 12 months follow-up. Effects were analyzed using linear mixed effect models.ResultsThere were no significant differences in work engagement, mental health, need for recovery and mindfulness between the intervention and control group after either 6- or 12-months follow-up. Additional analyses in mindfulness-related training compliance subgroups (high and low compliance versus the control group as a reference) and subgroups based on baseline work engagement scores showed no significant differences either.ConclusionsThis study did not show an effect of this worksite mindfulness-related multi-component health promotion intervention on work engagement, mental health, need for recovery and mindfulness after 6 and 12 months.Trial registrationNetherlands Trial Register NTR2199

一、研究目的
本研究旨在评估职场正念相关多组分健康促进干预方案对工作投入（work engagement）、心理健康、恢复需求（need for recovery）及正念（mindfulness）的干预效果。
二、研究方法
本研究采用随机对照试验设计，招募了两家科研机构的257名在职人员。干预组（n=129）接受针对性正念相关培训，并辅以电子辅导（e-coaching）；整个干预周期共计6个月。分别在基线、干预6个月及12个月随访节点，通过问卷采集工作投入、心理健康、恢复需求及正念水平相关数据。采用线性混合效应模型对干预效果进行统计分析。
三、研究结果
无论是干预后6个月还是12个月随访时，干预组与对照组在工作投入、心理健康、恢复需求及正念水平上均无显著组间差异。进一步针对正念培训依从性亚组（高依从性、低依从性以对照组作为参照）以及基线工作投入得分亚组开展的补充分析，同样未发现显著组间差异。
四、研究结论
本研究未发现该职场正念相关多组分健康促进干预方案在干预后6个月及12个月时，对工作投入、心理健康、恢复需求及正念水平存在显著影响。
