BACKGROUND
Previous studies have indicated that higher subjective well-being works as a protective factor for health. Some studies have already shown the effects of mindfulness-based interventions on improving subjective well-being. However, these studies targeted specific populations rather than the general public. Furthermore, they assessed either life evaluation or affective aspects of subjective well-being rather than the concept as a whole, including the eudemonic aspect of well-being.
OBJECTIVE
This study aims to investigate the effectiveness and cost-effectiveness of mindfulness-based cognitive therapy (MBCT) for improving the wholistic aspects of subjective well-being in healthy individuals.
METHODS
This study was an 8-week, randomized, parallel-group, superiority trial with a 2-month follow-up. Healthy individuals aged 20-65 years with scores lower than 25 on the Satisfaction With Life Scale (SWLS) were eligible to participate and randomly allocated to the MBCT group or the wait-list control group. The intervention program was developed by modifying an MBCT program to improve the well-being of a nonclinical population. The primary outcome was the difference between the two groups in mean change scores from the baseline on the SWLS. The secondary outcomes included scores on the Flourishing Scale and the Scale of Positive and Negative Experience as well as the incremental cost-effectiveness ratio.
RESULTS
This study began recruiting participants in July 2018 and recruitment was completed at the end of September 2019. Data collection and dataset construction was completed by the end of March 2020.
CONCLUSIONS
This study is unique in that it investigates MBCT's effects on the three different aspects of subjective well-being: life evaluation, affect, and eudemonia. It is limited, as the specific effect attributable to MBCT cannot be detected because of the lack of an active control group.

背景
以往研究表明，较高的主观幸福感可作为健康的保护因素。一些研究已显示基于正念的干预措施对改善主观幸福感的效果。然而，这些研究针对的是特定人群而非普通大众。此外，它们评估的是主观幸福感的生活评价或情感方面，而非包括幸福感的心理层面在内的整体概念。
目的
本研究旨在探讨基于正念的认知疗法（MBCT）对改善健康个体主观幸福感整体方面的有效性和成本效益。
方法
本研究为一项为期8周的随机平行组优效性试验，随访2个月。年龄在20 - 65岁、生活满意度量表（SWLS）得分低于25分的健康个体有资格参与，并随机分配至MBCT组或等待名单对照组。干预方案通过修改MBCT方案制定，以改善非临床人群的幸福感。主要结局是两组在SWLS上从基线开始的平均变化得分之差。次要结局包括蓬勃发展量表、正负体验量表的得分以及增量成本效益比。
结果
本研究于2018年7月开始招募参与者，2019年9月底完成招募。数据收集和数据集构建于2020年3月底完成。
结论
本研究的独特之处在于它调查了MBCT对主观幸福感三个不同方面的影响：生活评价、情感和心理层面。其局限性在于，由于缺乏积极对照组，无法检测到MBCT的具体效果。
