虽然基于正念的干预（MBIs）采用两种不同的做法，集中注意力（FA）和开放式监测（OM），MBIs中这些做法的综合交付排除了对它们的具体做法的影响或作用机制的理解。本研究的目的是隔离假设的活性成分和实践特定的机械目标的参与，通过创建结构上等同的干预措施，不同的活性成分（冥想练习）提供，并测试是否假设的组件差异参与的机械目标，他们声称从事。参与者是美国冥想者的代表，有轻度到重度的情感障碍。结构等效性的测量包括参与者水平（样本特征）、治疗水平（项目结构和持续时间、项目材料、班级规模、出勤率、家庭作业依从性等），和销售人员水平变量（培训、评级和依从性/忠诚度）。差异有效性的措施包括程序材料的分析和验证的差异机械目标参与（认知和情感技能和信念的参与者获得的冥想后，8周的培训）。结果表明，成功地创建了结构上等效的FA和OM程序，这些程序在参与者水平、治疗水平和患者水平变量上匹配。正如预期的那样，干预措施在程序材料和机械目标（获得的技能和信念）方面也有所不同。这些经过验证的8周FA和OM训练计划可以应用于未来的研究，以评估冥想的具体实践效果。
While mindfulness-based interventions (MBIs) employ two distinct practices, focused attention (FA) and open monitoring (OM), the integrated delivery of these practices in MBIs precludes understanding of their practice-specific effects or mechanisms of action. The purpose of this study is to isolate hypothesized active ingredients and practice-specific mechanistic target engagement by creating structurally equivalent interventions that differ only by the active ingredient (meditation practice) offered and to test whether the hypothesized components differentially engage the mechanistic targets that they are purported to engage. Participants were intended to be representative of American meditators and had mild to severe affective disturbances. Measures of structural equivalence included participant-level (sample characteristics), treatment-level (program structure and duration, program materials, class size, attendance, homework compliance, etc.), and instructor-level variables (training, ratings and adherence/fidelity). Measures of differential validity included analysis of program materials and verification of differential mechanistic target engagement (cognitive and affective skills and beliefs about meditation acquired by participants after the 8-week training). The results indicate successful creation of structurally equivalent FA and OM programs that were matched on participant-level, treatment-level, and instructor-level variables. The interventions also differed as expected with respect to program materials as well as mechanistic targets engaged (skills and beliefs acquired). These validated 8-week FA and OM training programs can be applied in future research to assess practice-specific effects of meditation.
