Van DamThe Mindful Attention Awareness Scale (MAAS) is one of the most popular measures of mindfulness, exhibiting promising psychometric properties and theoretically consistent relationships to brain activity, mindfulness-based intervention (MBI) outcomes, and mediation of MBI effects. The present study investigated the response patterns and scale properties in a large sample of undergraduate students (N = 414) using Item Response Theory analyses. The findings suggest that general statements of 「automatic inattentiveness」 or 「automatic pilot」 confer greater statistical information about the underlying latent trait. Evidence of limited abilities to report on mindlessness and of response bias to 「mindfulness-absent」 items suggests challenges to the construct validity of the MAAS. The current findings, along with preexisting data, suggest that reverse-scoring the scale may be inadequate to represent intentional attention or awareness. Further research is needed to determine which variations, components, and correlates of the numerous operationalizations of mindfulness are theoretically consistent and most salient to positive outcomes, especially in psychopathology.
正念注意覺知量表(MAAS)是最受歡迎的正念測量量表之一,具有良好的心理測量學特性,理論上與大腦活動、基於正念的幹預(MBI)結果以及MBI效應的中介作用保持一致。本研究以414名大學生為研究對象,運用項目反應理論對其反應模式和量表性質進行了研究。研究結果表明,「自動注意力不集中」或「自動駕駛」的一般性陳述提供了更多關於潛在特徵的統計信息。報告無意識的能力有限,以及對「無意識」項目的反應偏差的證據表明,MAA的結構有效性面臨挑戰。目前的研究結果和已有的數據表明,對量表進行反向評分可能不足以代表有意注意或意識。需要進一步的研究來確定在眾多的正念測量中,哪些變化、成分和相關因素在理論上是一致的,並且對積極的結果最為顯著,特別是在精神病理學方面。
