背景。日常生活活动（ADL）依赖在养老院是一个现实情况，我们基于最小数据集（MDS）中的项目描述ADL测量策略，以及三种ADL自我表现量表的创建、分布特征及其与其他测量指标的关系。
方法。从四个数据集获取的信息用于多步骤分析，该分析由四个研究目标指导：（1）确定MDS量表中存在的ADL子成分；（2）展示如何在分层和累加的ADL汇总量表中汇总这些项目；（3）描述在一个大型的七州MDS数据库中这些量表的基线和纵向分布特征；（4）评估这些量表与两个外部标准的关系。
结果。对七个MDS ADL自我表现变量的患病率和因子结构研究结果表明，这些项目可分为早期、中期和晚期丧失的ADL成分。创建了两种类型的ADL自我表现汇总测量指标：累加式和分层式。描述了这些量表的分布特征，以及它们与先前研究中报道的两个外部ADL标准的关系：首先作为预测护理人员照顾居民所花费时间的自变量；其次作为两项改善居民功能项目有效性研究中的因变量。
结论。基于现成的MDS数据的新ADL汇总量表，对于使用MDS功能自我表现项目来确定居民ADL状态的临床医生、项目审核员和研究人员应该是有用的。
Background. Dependency in activities of daily living (ADLs) is a reality within nursing homes, and we describe ADL measurement strategies based on items in the Minimum Data Set (MDS) and the creation and distributional properties of three ADL self-performance scales and their relationship to other measures.Methods. Information drawn from four data sets for a multistep analysis was guided by four study objectives: (1) to identify the subcomponents of ADLs that are present in the MDS battery; (2) to demonstrate how these items could be aggregated within hierarchical and additive ADL summary scales; (3) to describe the baseline and longitudinal distributional properties of these scales in a large, seven-state MDS database; and (4) to evaluate how these scales relate to two external criteria.Results. Prevalence and factor structure findings for seven MDS ADL self-performance variables suggest that these items can be placed into early, middle, and late loss ADL components. Two types of summary ADL self-performance measures were created: additive and hierarchical. Distributional properties of these scales are described, as is their relationship to two external ADL criteria that have been reported in prior studies: first as an independent variable predicting staff time involved in resident care; second as a dependent variable in a study of the efficacy of two programs to improve resident functioning.Conclusions. The new ADL summary scales, based on readily available MDS data, should prove useful to clinicians, program auditors, and researchers who use the MDS functional self-performance items to determine a resident's ADL status.
