Mindfulness has become increasingly popular over the years. In both clinical and research settings, mindfulness has been efficacious in reducing stress, anxiety, and depressive symptoms, and increasing overall quality of life and well-being. While numerous self-report measures aim to assess components of mindfulness, concerns have been raised surrounding the conceptualization, definition, and measurement of mindfulness. The present study examines the concurrent validity among both state and trait mindfulness measures, including the Toronto Mindfulness Scale (TMS), State Mindful Attention Awareness Scale (State MAAS), Mindfulness Attention Awareness Scale (MAAS), Five Facet Mindfulness Questionnaire (FFMQ), Freiburg Mindfulness Inventory (FMI), and Cognitive and Affective Mindfulness Scale Revised (CAMS-R). Two independent samples of 500 adults in the general U.S. population (Mage = 33.75) and 509 college students (Mage = 19.66), respectively, were recruited. All participants completed the aforementioned self-report measures online. With few exceptions, results were consistent across both samples and indicated strong convergent validity between self-report trait mindfulness measures and weak convergent validity between self-report state mindfulness measures. In addition, the FFMQ Observing and Nonreactivity subscales displayed poor construct validity among other measures purported to assess similar components of mindfulness. Findings from the present study demonstrate strong convergent validity across self-report trait mindfulness measures. However, results displayed weak convergent validity among self-report state mindfulness measures, thus raising questions regarding the overall validity of these measures. Results further suggest review of the FFMQ Observing and Nonreactivity facets.

多年来，正念变得越来越流行。在临床和研究环境中，正念可以有效减轻压力、焦虑和抑郁症状，并提高整体生活质量和幸福感。虽然许多自我报告措施旨在评估正念的组成部分，但人们对正念的概念化、定义和测量提出了担忧。本研究检验了状态和特质正念测量之间的并发有效性，包括多伦多正念量表（TMS）、状态正念注意力意识量表（州MAAS）、正念注意力意识量表（MAAS）、五方面正念问卷（FFMQ）、弗莱堡正念量表 (FMI) 和修订后的认知和情感正念量表 (CAMS-R)。法师 =33.75）和509名大学生（法师 = 19.66），分别被招募。所有参与者在线完成上述自我报告措施。除少数例外，两个样本的结果都是一致的，并且表明自我报告特质正念测量之间的收敛效度较强，而自我报告状态正念测量之间的收敛效度较弱。此外，与其他旨在评估正念类似组成部分的措施相比，FFMQ 观察和非反应性分量表的结构效度较差。本研究的结果表明，自我报告特质正念测量具有很强的收敛效度。然而，结果显示自我报告状态正念测量之间的收敛效度较弱，从而引发了有关这些测量的整体有效性的问题。
