瑜伽干预具有相当大的异质性，是多维度的，并可能以不同的方式影响健康。然而，大多数关于瑜伽对健康和福祉影响的研究报告都没有充分描述瑜伽干预措施的组成部分。因此，在研究中进行比较或了解瑜伽干预的特定方面的相对效果是不可能的。为了解决这个问题，我们创建了瑜伽基本属性问卷（EPYQ）项目，这是NCCAM资助的一组研究，旨在为瑜伽研究人员开发一个翻译工具。在这里，我们详细描述了EPYQ项目中使用的方法和开发过程。该项目包括四个主要阶段。第一阶段的目的是通过进行全面系统的文献综述，并与包括各种瑜伽教师和学生在内的利益相关者进行焦点小组讨论，全面了解瑜伽的相关方面。在第二阶段，利用第一阶段的信息为原型调查表编制了一个潜在调查表项目库。认知访谈进行了初步EPYQ项目，以评估感知的清晰度，意义和每个项目的重要性。在第三阶段，原型问卷管理的两个大样本的瑜伽学生和教练。招募练习或教授瑜伽的军人和退伍军人（n = 329）参加。采用因子分析和项目反应理论进行因子分析和项目筛选。第四阶段正在进行中，将收集最终仪器的可靠性和有效性数据。预计将于2016年公布结果。EPYQ将提供一个客观的工具来描述瑜伽干预的各种成分的数量，最终允许研究人员将特定的瑜伽成分与健康益处联系起来，并促进针对特定健康状况的瑜伽干预设计。
Yoga interventions have considerable heterogeneity, are multi-dimensional, and may impact health in different ways. However, most research reports regarding the effects of yoga on health and wellbeing do not adequately describe the components of the yoga interventions being used. Thus, drawing comparisons across studies or understanding the relative effects of specific aspects of a yoga intervention are rarely possible. To address this problem, we created the Essential Properties of Yoga Questionnaire (EPYQ) Project, an NCCAM-funded set of studies to develop a translational tool for yoga researchers. Here we describe the methods and developmental processes used in the EPYQ Project in detail. The project consists of four main phases. Phase I was designed to gain a comprehensive understanding of the relevant aspects of yoga by conducting a comprehensive systematic literature review and conducting focus groups with stakeholders including a wide variety of yoga teachers and students. In Phase II, a pool of potential questionnaire items was developed for the prototypic questionnaire using information from Phase I. Cognitive interviews were conducted with the preliminary EPYQ items to assess the perceived clarity, meaning, and importance of each item. In Phase III, the prototypic questionnaire was administered to two large samples of yoga students and instructors. Military personnel and veterans who practiced or taught yoga (n = 329) were recruited to participate. Factor analysis and item response theory were used to identify factors and select the final questionnaire items. Phase IV is ongoing and will collect reliability and validity data on the final instrument. Results are expected to be available in 2016. The EPYQ will provide an objective tool for describing the amount of various components of yoga interventions, eventually allowing researchers to link specific yoga components to health benefits, and facilitating the design of yoga interventions for specific health conditions.
