To determine the structure and statistical reliability of the federally mandated Minimum Data Set (MDS).
Confirmatory, hypothesis-testing factor analysis was performed on MDS protocols of 733 nursing home residents.
All participants were residents of the Philadelphia Geriatric Center.
Participants represented consecutively admitted skilled and intermediate care residents and another pool of residents with probable dementia.
MDS protocols were completed by nurse care coordinators. Item composites hypothesized represented the domains of cognition, activities of daily living, time use, social quality, depression, and problem behaviors.
For higher functioning residents (n = 336) and for all residents together, all domain clusters except social quality were confirmed. None of the domain clusters were confirmed within the more impaired (n = 391) group.
The MDS does provide usable indicators of five areas of basic competence of nursing home residents. Lack of reliability in rating many aspects of the behavior and states of cognitively impaired residents is evident, however. Improvement of such measures and rating procedures constitutes a major research priority.
确定联邦政府规定的最小数据集（MDS）的结构和统计可靠性。
对733名养老院居民的MDS协议进行验证性假设检验因子分析。
所有参与者均为费城老年医学中心的居民。
参与者包括连续入住的熟练护理和中级护理居民以及另一组可能患有痴呆症的居民。
MDS协议由护士护理协调员完成。假设的项目综合指标代表认知、日常生活活动、时间利用、社会质量、抑郁和问题行为等领域。
对于功能较高的居民（n = 336）以及所有居民而言，除社会质量外的所有领域集群均得到确认。在功能受损更严重的居民组（n = 391）中，没有一个领域集群得到确认。
MDS确实提供了养老院居民五个基本能力领域的可用指标。然而，在对认知受损居民的行为和状态的许多方面进行评分时，可靠性不足是明显的。改进此类测量方法和评分程序是一项主要的研究重点。
