Comparison of mindfulness training and acceptance and commitment therapy in a workplace setting: results from a randomized controlled trial
本研究比较了正念训练和接纳承诺疗法在工作场所的效果，发现两者均能减轻压力、改善正念和睡眠质量，但接纳承诺疗法在帮助员工行为符合个人价值观方面略优，两者均未减少工作限制。
Mindfulness interventions have become a common feature of worksite stress management provision.However, the evidence underpinning these interventions continues to attract scrutiny, with unresolved questions surrounding: the generalizability of mindfulness research findings to real-world workplace training applications, comparability of different mindfulness approaches offered in workplace settings, and effects on job performance.The current trial contributes to the literature by exploring effects of mindfulness training (MT) and acceptance and commitment therapy (ACT), which were delivered to staff in the same healthcare organization.Participants were randomly assigned to a 4-session MT program (n = 63), a 4-session ACT program (n = 67), or a waiting list control group (n = 69).Study measures were administered on five occasions spread across a 6-month period.Results indicated that both MT and ACT reduced perceived stress and improved mindfulness and sleep quality when compared to the control group.ACT showed slight superiority in helping employees align their behaviour with personal values.Neither MT nor ACT was effective in reducing work limitations.We consider explanations for equivocal effects on job performance outcomes, and highlight the importance of testing the effectiveness of worksite mindfulness interventions under ecologically valid conditions.
