Stress and back pain are two key factors leading to sickness absence at work. Recent research indicates that yoga can be effective for reducing perceived stress, alleviating back pain, and improving psychological well-being.
To determine the effectiveness of a yoga-based intervention for reducing perceived stress and back pain at work.
Participants were recruited from a British local government authority and randomized into a yoga group who received one 50 min Dru Yoga session each week for 8 weeks and a 20 min DVD for home practice and a control group who received no intervention. Baseline and end-programme measurements of self-reported stress, back pain and psychological well-being were assessed with the Perceived Stress Scale, Roland Morris Disability Questionnaire and the Positive and Negative Affect Scale.
There were 37 participants in each group. Analysis of variance and multiple linear regression showed that in comparison to the control group, the yoga group reported significant reductions in perceived stress and back pain, and a substantial improvement in psychological well-being. When compared with the control group at the end of the programme, the yoga group scores were significantly lower for perceived stress, back pain, sadness and hostility, and substantially higher for feeling self-assured, attentive and serene.
The results indicate that a workplace yoga intervention can reduce perceived stress and back pain and improve psychological well-being. Larger randomized controlled trials are needed to determine the broader efficacy of yoga for improving workplace productivity and reducing sickness absence.
压力和背痛是导致工作缺勤的两个关键因素。最近的研究表明,瑜伽可以有效减轻感知压力、缓解背痛和改善心理健康。
确定基于瑜伽的干预措施在减轻工作中的感知压力和背痛方面的有效性。
参与者从英国地方政府机构招募,随机分为瑜伽组和对照组。瑜伽组每周接受一次 50 分钟的 Dru 瑜伽课程,为期 8 周,并接受 20 分钟的 DVD 进行家庭练习;对照组不接受干预。使用感知压力量表、Roland Morris 残疾问卷和积极与消极情绪量表评估基线和项目结束时的自我报告压力、背痛和心理健康状况。
每组有 37 名参与者。方差分析和多元线性回归显示,与对照组相比,瑜伽组报告感知压力和背痛显著减轻,心理健康显著改善。与项目结束时的对照组相比,瑜伽组的感知压力、背痛、悲伤和敌意得分显著降低,自信、专注和宁静得分显著升高。
结果表明,工作场所瑜伽干预可以减轻感知压力和背痛,改善心理健康。需要更大规模的随机对照试验来确定瑜伽在提高工作场所生产力和减少缺勤方面的更广泛效果。
