The Mindfulness to Meaning Theory provides a detailed process model of the mechanisms by which mindfulness may promote well-being. Central to the Mindfulness to Meaning Theory is the mindful reappraisal hypothesis (MRH), which suggests mindfulness training promotes well-being by facilitating positive reappraisal. Emerging evidence from interconnected domains of research supports the MRH. However, it remains unclear whether mindful reappraisal continues to develop after a mindfulness training course and whether this continued development encourages well-being over time. As such, this randomized controlled study compared participants receiving a mindfulness-based stress reduction (MBSR) course with participants receiving no mindfulness training on positive reappraisal use and well-being over the course of 6 years. Latent growth curve modeling revealed that mindfulness training increased well-being by significantly increasing the trajectory of positive reappraisal over time. The MRH was then unpacked by examining whether MBSR also stimulated decentering and broadened awareness, core components of the MRH. Multivariate path analysis revealed that mindfulness training increased decentering, which in turn broadened awareness, which was then associated with positive reappraisal, ultimately promoting well-being. Taken together, these findings suggest that MBSR cultivates a downstream cascade of adaptive psychological processes that continue to promote quality of life 6-years after mindfulness training.

正念到意义理论的正念重估假设建模：随机对照研究的纵向数据复制

正念意义理论提供了一个详细的过程模型，说明正念可以促进幸福的机制。正念到意义理论的核心是正念重估假说（MRH），它表明正念训练通过促进积极的重估来促进幸福感。来自相互关联的研究领域的新证据支持 MRH。然而，尚不清楚在正念培训课程后是否会继续发展正念重新评估，以及这种持续发展是否会随着时间的推移而促进幸福感。因此，这项随机对照研究将接受基于正念减压 (MBSR) 课程的参与者与未接受正念再评估使用和幸福感培训的参与者进行了 6 年的比较。潜在增长曲线模型显示，随着时间的推移，正念训练通过显着增加积极重新评估的轨迹来增加幸福感。然后通过检查 MBSR 是否也刺激了 MRH 的核心组成部分——去中心化和扩大意识，对 MRH 进行了拆解。多变量路径分析显示，正念训练增加了去中心化，这反过来又扩大了意识，然后与积极的重新评估相关联，最终促进了幸福感。综上所述，这些发现表明 MBSR 培养了下游级联的适应性心理过程，这些过程在正念训练 6 年后继续提高生活质量。然后通过检查 MBSR 是否也刺激了 MRH 的核心组成部分——去中心化和扩大意识，对 MRH 进行了拆解。多变量路径分析显示，正念训练增加了去中心化，这反过来又扩大了意识，然后与积极的重新评估相关联，最终促进了幸福感。综上所述，这些发现表明 MBSR 培养了下游级联的适应性心理过程，这些过程在正念训练 6 年后继续提高生活质量。然后通过检查 MBSR 是否也刺激了 MRH 的核心组成部分——去中心化和扩大意识，对 MRH 进行了拆解。多变量路径分析显示，正念训练增加了去中心化，这反过来又扩大了意识，然后与积极的重新评估相关联，最终促进了幸福感。综上所述，这些发现表明 MBSR 培养了下游级联的适应性心理过程，这些过程在正念训练 6 年后继续提高生活质量。
