早期所有的研究都将五面正念问卷作为五个独立的量表（一个测量五个方面中的每一个），但几乎没有方法学工作独立地检查了五个方面的心理测量结构。我们使用因子分析法来解决这个问题。方法采用探索性因子模型和验证性因子模型对522名在线成人的问卷调查数据进行拟合。研究结果在454名接受药物使用障碍后护理的成年人样本中得到了重复。结果平行分析表明，在这两个样本中，这五个方面都存在多因素。探索性因素模型表明，方法因素存在于意识行为（使用术语“分心”的项目）和描述方面（反向得分的项目）。在两个样本中，验证性因子模型对所有方面的拟合都很差。在后续分析中，当方法因素被包含在双因素模型中时，模型拟合在意识作用和描述方面有了很大的提高。对于FFMQ短表单的切面，模型拟合也比全长切面更好。在这两个样本中，短形面和原始面与外部标准相似。结论FFMQ各面均不符合一维因子模型；然而，后续分析表明，每一种都可以被认为是单维的。最初的测试表明，这些方面的多维度并没有实质性地影响它们与其他心理构念的关系，这表明在某些目的下，多维度可以被忽略。使用短形式的facet或潜在变量模型（例如，双因素规范）都是在需要时处理多维性的可行解决方案。
ObjectiveNearly all studies treat the Five Facet Mindfulness Questionnaire as five independent scales (one measuring each of the five facets), yet almost no methodological work has examined the psychometric structure of the facets independently. We address this issue using factor analytic methods.MethodsExploratory and confirmatory factor models were fit to item response data from a sample of 522 adults recruited online. Findings were replicated in a sample of 454 adults receiving aftercare for substance use disorder.ResultsParallel analysis suggested multiple factors for all five facets, in both samples. Exploratory factor models suggested the presence of method factors on the acting with awareness (items using the term “distraction”) and describing facets (items that were reverse-scored). Confirmatory factor models fit poorly for all facets, in both samples. In follow-up analyses, model fit improved substantially on the acting with awareness and describing facets when method factors were included in a bifactor model. Model fit was also better for the facets of FFMQ short forms than for the full-length facets. The short-form facets and original facets correlated similarly with external criteria in both samples.ConclusionsNone of the FFMQ facets fit a unidimensional factor model; yet, follow-up analyses suggested that each can be considered substantively unidimensional. Initial tests suggest that the facets’ multidimensionality did not materially impact their relation to other psychological constructs, suggesting that multidimensionality can be ignored for some purposes. The use of short-form facets or latent variable models (e.g., bifactor specifications) are both viable solutions for addressing multidimensionality when desired.
