Objective: Following bereavement, yearning and grief rumination are repetitive cognitive processes that can lead to disordered grief. Mindfulness training (MT) has been shown to reduce maladaptive repetitive thought. The current quasi-randomized controlled trial examined the feasibility, acceptability, and preliminary efficacy of MT for bereavement-related grief. Method: Ninety-five widow(er)s (Mage = 67.5, 79% women, 98% White) between 6 months to 4 years post-loss were assigned to a 6-week MT intervention or a progressive muscle relaxation (PMR) intervention, or a wait-list condition. Outcome measures were grief severity (Revised Inventory of Complicated Grief), yearning (Yearning in Situations of Loss), rumination (Utrecht Grief Rumination Scale), and decentering (Experiences Questionnaire-Decentering) assessed at baseline, Weeks 2 and 4 of intervention, post-intervention, and 1-month post-intervention. Growth curve analysis examined group differences in rates of improvement in outcomes through follow-up and associations with improvement in grief severity. Results: The MT and PMR groups showed significant rates of decline in grief severity and yearning, though only the PMR group showed a greater rate of decline in grief severity than wait-list. All groups showed significant rates of decline in grief rumination. The PMR and wait-list groups showed significant rates of increase in decentering compared to the MT group. Conclusions: Results support the feasibility and acceptability of MT and PMR for widow(er)s as well as the preliminary efficacy of PMR for improving grief severity in widow(er)s compared to a wait-list control condition. With replication, PMR could be a standalone intervention for non-disordered grief or a component of treatment for disordered grief. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

一项针对寡妇和鳏夫悲伤的两种身心干预的对照试验。

目标：在丧亲之痛之后，渴望和悲伤沉思是重复的认知过程，可导致无序的悲伤。正念训练 (MT) 已被证明可以减少适应不良的重复思维。当前的准随机对照试验检验了 MT 对丧亲之痛的可行性、可接受性和初步疗效。方法：将失去后 6 个月至 4 年的 95 名寡妇（法师 = 67.5，79% 女性，98% 白人）分配到 6 周的 MT 干预或渐进式肌肉放松 (PMR) 干预，或等待名单条件。结果测量是在基线评估的悲伤严重程度（修订的复杂悲伤清单）、渴望（在失去的情况下渴望）、沉思（乌得勒支悲伤沉思量表）和去中心化（体验问卷-去中心化），干预的第 2 周和第 4 周、干预后和干预后 1 个月。生长曲线分析通过​​随访检查了结果改善率的组差异以及与悲伤严重程度改善的关联。结果：MT 和 PMR 组在悲痛程度和渴望方面表现出显着下降率，但只有 PMR 组在悲痛程度方面的下降率高于等待名单。所有组都显示出悲伤沉思的显着下降率。与 MT 组相比，PMR 和候补名单组的偏心率显着增加。结论：结果支持 MT 和 PMR 对寡妇 (er) 的可行性和可接受性，以及 PMR 在改善寡妇 (er) 与等待名单控制条件相比的悲伤严重程度方面的初步功效。通过复制，PMR 可以是非无序悲伤的独立干预措施，也可以是无序悲伤治疗的一个组成部分。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
