Although yoga shows promise as a treatment for posttraumatic stress disorder (PTSD), there are few randomized controlled trials that demonstrate significant benefits for individuals with PTSD. The present study addresses this need by comparing the effects of a holistic yoga program (HYP) to that of a wellness lifestyle program (WLP) on PTSD symptom severity with a randomized clinical trial.
The sample consisted of 209 participants (91.4% veterans; 66% male; 61.7% White) who met diagnostic criteria for PTSD at baseline. Participants were randomly assigned to attend one of the 2 weekly interventions for 16 weeks. The HYP consisted of yoga instruction, while the WLP consisted of didactics, discussions, and walking. PTSD severity was measured using the Clinician Administered PTSD Scale (CAPS-5) and the PTSD Checklist (PCL-5).
Analyses revealed that the HYP reduced PTSD severity measured by the CAPS-5 significantly more than the WLP at treatment end (mean difference = -5.4, effect size = 0.46, < .001), but not at 7-month follow up (mean difference = -0.9, = .603). Similarly, the HYP reduced PTSD severity measured by the PCL-5 significantly more than the WLP at treatment end (difference = -6.0, = .001), but not at 7-month follow up (mean difference = -1.0, = .682).
Yoga may be an effective intervention for PTSD in addition to standard treatments. Future yoga trials should consider adding a social component to interventions or booster classes to maintain effects long term. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
尽管瑜伽在治疗创伤后应激障碍(PTSD)方面显示出一定的前景,但很少有随机对照试验证明其对 PTSD 个体有显著益处。本研究通过一项随机临床试验,比较整体瑜伽方案(HYP)与健康生活方式方案(WLP)对 PTSD 症状严重程度的影响,以满足这一需求。
该样本包括 209 名参与者(91.4%为退伍军人;66%为男性;61.7%为白人),他们在基线时符合 PTSD 的诊断标准。参与者被随机分配参加每周 2 次的干预,共 16 周。HYP 包括瑜伽指导,而 WLP 则包括讲座、讨论和散步。使用临床医生管理 PTSD 量表(CAPS-5)和 PTSD 检查表(PCL-5)来衡量 PTSD 严重程度。
分析显示,HYP 在治疗结束时显著降低了 CAPS-5 测量的 PTSD 严重程度,比 WLP 高 5.4 分,效应大小为 0.46,<0.001,但在 7 个月的随访时没有差异(平均差异=-0.9,=0.603)。同样,HYP 在治疗结束时显著降低了 PCL-5 测量的 PTSD 严重程度,比 WLP 高 6.0 分,<0.001,但在 7 个月的随访时没有差异(平均差异=-1.0,=0.682)。
瑜伽除了标准治疗外,可能是 PTSD 的有效干预措施。未来的瑜伽试验应考虑在干预措施或强化课程中增加社交成分,以维持长期效果。
