We examined the factor structure and psychometric properties of the Mindful Attention Awareness Scale (MAAS) in a sample of 810 undergraduate students. Using common exploratory factor analysis (EFA), we obtained evidence for a 1-factor solution (41.84% common variance). To confirm unidimensionality of the 15-item MAAS, we conducted a 1-factor confirmatory factor analysis (CFA). Results of the EFA and CFA, respectively, provided support for a unidimensional model. Using differential item functioning analysis methods within item response theory modeling (IRT-based DIF), we found that individuals with high and low levels of nonattachment responded similarly to the MAAS items. Following a detailed item analysis, we proposed a 5-item short version of the instrument and present descriptive statistics and composite score reliability for the short and full versions of the MAAS. Finally, correlation analyses showed that scores on the full and short versions of the MAAS were associated with measures assessing related constructs. The 5-item MAAS is as useful as the original MAAS in enhancing our understanding of the mindfulness construct.
我们在810名本科生样本中检验了正念注意觉知量表（MAAS）的因子结构和心理测量特性。使用常见的探索性因子分析（EFA），我们获得了单因子解（共同方差为41.84%）的证据。为了证实15项MAAS的单维性，我们进行了单因子验证性因子分析（CFA）。EFA和CFA的结果分别为单维模型提供了支持。在项目反应理论建模（基于IRT的DIF）中使用差异项目功能分析方法，我们发现非执着程度高和低的个体对MAAS项目的反应相似。经过详细的项目分析，我们提出了该量表的5项简短版本，并给出了MAAS简短版和完整版的描述性统计及综合得分信度。最后，相关性分析表明，MAAS完整版和简短版的得分与评估相关构念的指标相关。5项MAAS在增强我们对正念构念的理解方面与原始MAAS一样有用。
