Preliminary studies have demonstrated the efficacy of Transcendental Meditation (TM) for treating posttraumatic stress disorder (PTSD). The present study extended previous research with a pilot trial of TM as a treatment for PTSD via a single-blinded, randomized controlled design. veterans with PTSD (N = 40) were assigned to a TM intervention or treatment-as-usual (TAU) control group. Participants in the TM group engaged in 16 sessions over 12 weeks, primarily in a 60-min group format. Change in PTSD symptoms, measured via the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) was the primary outcome. Secondary outcomes included self-reported PTSD symptoms, depression, anxiety, sleep difficulties, anger, and quality of life (QoL). Assessments were conducted at baseline and 3-month follow-up. Mean CAPS-5 score decreases were significantly larger for participants in the TM group (M = -11.28, 95% CI [-17.35, -5.20]), compared to the TAU group (M = −1.62, 95% CI [-6.77, 3.52]), p = .012, d = -0.84. At posttest, 50.0% of veterans in the TM group no longer met PTSD diagnostic criteria as compared to 10.0% in the TAU group, p = .007. Adjusted mean changes on self-report measures of PTSD symptoms, depression, anxiety, and sleep difficulties indicated significant reductions in the TM group compared to TAU, ds = .80–1.16. There were no significant group differences regarding anger or QoL. These findings demonstrate the efficacy of TM as a treatment for veterans with PTSD and for comorbid symptoms. Combined with other research, they suggest that TM may be a tolerable, non–trauma-focused PTSD treatment.

先验冥想作为退伍军人创伤后应激障碍治疗的随机对照试验

初步研究证明了先验冥想 (TM) 对治疗创伤后应激障碍 (PTSD) 的功效。本研究扩展了先前的研究，通过单盲、随机对照设计对 TM 作为 PTSD 的治疗进行了初步试验。患有 PTSD 的退伍军人 ( N = 40) 被分配到 TM 干预组或照常治疗 (TAU) 对照组。TM 组的参与者在 12 周内参加了 16 次会议，主要以 60 分钟的小组形式进行。通过DSM-5的临床医生管理的 PTSD 量表测量 PTSD 症状的变化（CAPS-5）是主要结果。次要结局包括自我报告的 PTSD 症状、抑郁、焦虑、睡眠困难、愤怒和生活质量 (QoL)。在基线和 3 个月的随访中进行了评估。与 TAU 组（M = -1.62，95 % CI [-6.77 , 3.52]), p = .012, d = -0.84。在后测中，TM 组 50.0% 的退伍军人不再符合 PTSD 诊断标准，而 TAU 组为 10.0%，p= .007。对 PTSD 症状、抑郁、焦虑和睡眠困难的自我报告测量的调整后平均变化表明，与 TAU 相比，TM 组显着降低，d s = .80–1.16。在愤怒或生活质量方面没有显着的组间差异。这些发现证明了 TM 作为治疗患有 PTSD 的退伍军人和合并症的疗效。结合其他研究，他们认为 TM 可能是一种可耐受的、非以创伤为重点的 PTSD 治疗。
