五方面正念问卷（FFMQ）是一种自我报告的正念测量方法，有几种不同长度的形式，包括FFMQ-39，FFMQ-24和FFMQ-15。我们使用项目反应理论分析，直接比较这三种forms.MethodsData的功能，从非临床亚马逊土耳其机械研究（N= 522）和研究的善后处理个人物质使用障碍（combinedN= 454）。三个FFMQ形式的项目和测试功能进行了研究和compared.ResultsAll 39个项目密切相关的方面的潜变量，和项目歧视在一个类似的范围内的潜在的正念结构。项目提供更多的信息，在低到中等范围内的潜在正念比在高范围。当测量处于高潜正念范围的个体时，FFMQ-39五个方面中的三个方面的分数是不可靠的，这是由于项目反应中的天花板效应造成的。在高范围内的正念的可靠性进一步减少在FFMQ-24和FFMQ-15，这样的短形式可能是不适合的应用程序，需要可靠的测量在高range.ConclusionsResults建议现有的FFMQ项目池不能减少而不产生负面影响的整体可靠性或跨度的正念的可靠性进行评估。条件测验的信度曲线和项目功能参数可以帮助调查人员根据他们希望达到的可靠性和他们必须可靠测量的潜在正念范围来定制他们对FFMQ形式的选择。
ObjectivesThe Five Facet Mindfulness Questionnaire (FFMQ) is a self-report measure of mindfulness with forms of several different lengths, including the FFMQ-39, FFMQ-24, and FFMQ-15. We use item response theory analysis to directly compare the functioning of these three forms.MethodsData were drawn from a non-clinical Amazon Mechanical Turk study (N= 522) and studies of aftercare treatment of individuals with substance use disorders (combinedN= 454). The item and test functioning of the three FFMQ forms were studied and compared.ResultsAll 39 items were strongly related to the facet latent variables, and the items discriminated over a similar range of the latent mindfulness constructs. Items provided more information in the low-to-medium range of latent mindfulness than in the high range. Scores in three of the five FFMQ-39 facets were unreliable when measuring individuals in the high range of latent mindfulness, resulting from ceiling effects in item responses. Reliability in the high range of mindfulness was further reduced in the FFMQ-24 and FFMQ-15, such that short forms may be ill-suited for applications that require reliable measurement in the high range.ConclusionsResults suggest the existing FFMQ item pool cannot be reduced without negatively affecting either overall reliability or the span of mindfulness over which reliability is assessed. Conditional test reliability curves and item functioning parameters can aid investigators in tailoring their choice of FFMQ form to the reliability they hope to achieve and to the range of latent mindfulness over which they must reliably measure.
