Designing and validation of a yoga-based intervention for obsessive compulsive disorder

Some yoga-based practices have been found to be useful for patients with obsessive compulsive disorder (OCD). The authors could not find a validated yoga therapy module available for OCD. This study attempted to formulate a generic yoga-based intervention module for OCD. A yoga module was designed based on traditional and contemporary yoga literature. The module was sent to 10 yoga experts for content validation. The experts rated the usefulness of the practices on a scale of 1–5 (5 = extremely useful). The final version of the module was pilot-tested on patients with OCD (<i>n</i> = 17) for both feasibility and effect on symptoms. Eighty-eight per cent (22 out of 25) of the items in the initial module were retained, with modifications in the module as suggested by the experts along with patients’ inputs and authors’ experience. The module was found to be feasible and showed an improvement in symptoms of OCD on total Yale-Brown Obsessive-Compulsive Scale (YBOCS) score (<i>p</i> = 0.001). A generic yoga therapy module for OCD was validated by experts in the field and found feasible to practice in patients. A decrease in the symptom scores was also found following yoga practice of 2 weeks. Further clinical validation is warranted to confirm efficacy.

已有研究证实，部分基于瑜伽的训练方法对强迫症（Obsessive Compulsive Disorder，OCD）患者具有积极辅助效用。但本研究团队尚未发现针对OCD的经过有效性验证的标准化瑜伽治疗模块。为此，本研究旨在开发一款通用的针对强迫症的瑜伽干预模块：研究人员结合传统与当代瑜伽文献设计了初始瑜伽治疗模块，并将其提交给10位瑜伽领域专家开展内容效度验证。专家们以1-5分制（5分代表极具实用性）对模块内训练方法的实用性进行评分。最终版模块针对17名OCD患者开展了预试验，以评估其临床可行性与对症状的改善效果。初始模块中共25项条目，最终保留了88%（22项），并结合专家建议、患者反馈与研究团队的实践经验对模块进行了优化调整。研究结果显示该模块具备临床可行性，且能显著改善OCD患者的耶鲁-布朗强迫症量表（Yale-Brown Obsessive-Compulsive Scale，YBOCS）总分（p=0.001）。本研究开发的通用OCD瑜伽治疗模块经领域专家验证有效，且在患者群体中具备实践可行性；受试者接受为期2周的瑜伽训练后，其强迫症症状评分出现显著降低。未来仍需开展进一步的临床验证以确认该模块的实际疗效。
