Abstract: The item discrimination, difficulty and information peak function of the item response theory are used to revise Mindful Attention Awareness Scale developed by Brown &Ryan(2003). Data collected from a sample of Chinese middle school teachers were submitted to analysis with MULTILOG7.03 software and the results suggested that MAAS exhibited promising psychometric properties and the scale satisfied on dimension hypothesis. The is sufficiently accurate to survey the status of mindfulness of Chinese teachers. The conclusions were drawn as as: 1) The item discrimination a, threshold b of the scale were satisfactory. 2) The test information peak function of 6 item shorten scale was quite high and the scale had a reasonable reliability. 3) The indicators of the Confirmative Factor Analysis (CFA) meet the requirements.

摘要： 正念注意觉知量表(MAAS)是测量正念注意水平最常用的量表之一,以中小学教师为被试,以项目反应理论用方法与技术对量表各项目的区分度、域值和信息函数峰值4个参数做了分析探讨。结果显示MMAS支持单维性假设,具有良好的心理测量学指标,对正念注意水平的测量具有较高的精准性。量表存在6个信息量很高的项目,其信息量之和接近量表总信息量的70%,提示这几个项目可以构成一个简式量表。对新量表做验证性因素分析,各项指标达到要求。
