Loving-kindness meditation is a practice designed to enhance feelings of kindness and compassion for self and others. Loving-kindness meditation involves repetition of phrases of positive intention for self and others. We undertook an open pilot trial of loving-kindness meditation for veterans with posttraumatic stress disorder (PTSD). Measures of PTSD, depression, self-compassion, and mindfulness were obtained at baseline, after a 12-week loving-kindness meditation course, and 3 months later. Effect sizes were calculated from baseline to each follow-up point, and self-compassion was assessed as a mediator. Attendance was high; 74% attended 9-12 classes. Self-compassion increased with large effect sizes and mindfulness increased with medium to large effect sizes. A large effect size was found for PTSD symptoms at 3-month follow-up (d = -0.89), and a medium effect size was found for depression at 3-month follow-up (d = -0.49). There was evidence of mediation of reductions in PTSD symptoms and depression by enhanced self-compassion. Overall, loving-kindness meditation appeared safe and acceptable and was associated with reduced symptoms of PTSD and depression. Additional study of loving-kindness meditation for PTSD is warranted to determine whether the changes seen are due to the loving-kindness meditation intervention versus other influences, including concurrent receipt of other treatments.
慈心冥想是一种旨在增强对自我和他人的友善和同情的练习。慈心冥想包括对自我和他人的积极意图进行重复。我们对患有创伤后应激障碍（PTSD）的退伍军人进行了慈心冥想的开放性试点试验。在基线、为期 12 周的慈心冥想课程结束后以及 3 个月后，我们测量了 PTSD、抑郁、自我同情和正念的情况。从基线到每次随访点计算了效应大小，并评估了自我同情作为中介。出勤率很高；74%的人参加了 9-12 节课。自我同情随着较大的效应大小而增加，正念随着中到大的效应大小而增加。在 3 个月的随访中，PTSD 症状出现了较大的效应大小（d=-0.89），在 3 个月的随访中，抑郁出现了中等效应大小（d=-0.49）。有证据表明，自我同情的增强可以缓解 PTSD 症状和抑郁。总体而言，慈心冥想似乎是安全且可接受的，并且与 PTSD 和抑郁症状的减轻有关。需要进一步研究慈心冥想对 PTSD 的作用，以确定所看到的变化是由于慈心冥想干预还是其他因素所致，包括同时接受其他治疗。
