瑜伽干预措施是多种多样的，并且在多个维度上有所不同。这些维度可能以不同的方式或通过不同的机制影响心理和身体健康结果。然而，大多数关于瑜伽对健康影响的研究都没有充分描述或量化正在实施的干预措施的组成部分。由于缺乏细节，研究人员无法对研究进行比较，并限制了我们对瑜伽干预不同方面的相对影响的理解。为了解决这个问题，我们开发了瑜伽问卷的基本属性（EPYQ），它使研究人员能够客观地描述他们的干预措施。我们在此介绍该措施开发项目最后阶段的可靠性和有效性数据。分析确定了 EPYQ 测量的瑜伽干预的 14 个关键维度：接受/同情、收束、身体意识、呼吸、教练提及的健康益处、个人注意力、冥想和正念、精神和情感意识、身体、主动姿势、恢复姿势、社交方面、灵性和瑜伽哲学。通过内部一致性和重测可靠性分析评估，EPYQ 表现出良好的可靠性，并且有证据表明 EPYQ 是瑜伽多个维度的有效衡量标准。该措施可供临床医生和研究人员使用。结果表明，目前，经过培训的客观评估者应该对干预措施进行评分，以避免参考框架错误和潜在的评级偏差，但可以开发替代方法。 EPYQ 将使研究人员能够将特定的瑜伽维度与可识别的健康结果联系起来，并针对特定条件优化瑜伽干预措施的设计。
Yoga interventions are heterogeneous and vary along multiple dimensions. These dimensions may affect mental and physical health outcomes in different ways or through different mechanisms. However, most studies of the effects of yoga on health do not adequately describe or quantify the components of the interventions being implemented. This lack of detail prevents researchers from making comparisons across studies and limits our understanding of the relative effects of different aspects of yoga interventions. To address this problem, we developed the Essential Properties of Yoga Questionnaire (EPYQ), which allows researchers to objectively characterize their interventions. We present here the reliability and validity data from the final phases of this measure-development project. Analyses identified fourteen key dimensions of yoga interventions measured by the EPYQ: acceptance/compassion, bandhas, body awareness, breathwork, instructor mention of health benefits, individual attention, meditation and mindfulness, mental and emotional awareness, physicality, active postures, restorative postures, social aspects, spirituality, and yoga philosophy. The EPYQ demonstrated good reliability, as assessed by internal consistency and test-retest reliability analysis, and evidence suggests that the EPYQ is a valid measure of multiple dimensions of yoga. The measure is ready for use by clinicians and researchers. Results indicate that, currently, trained objective raters should score interventions to avoid reference frame errors and potential rating bias, but alternative approaches may be developed. The EPYQ will allow researchers to link specific yoga dimensions to identifiable health outcomes and optimize the design of yoga interventions for specific conditions.
