认知功能下降和认知障碍的发生可能是老年人需要非正式援助和正式保健的重要预测因素。本文介绍了为老年人资产和健康动态（AHEAD）研究开发的认知功能的措施，该研究涉及约6500名70岁及以上的美国人。这项研究旨在调查家庭和经济资源支出对健康的影响。评估的认知措施Bt心理测量特性和缺失的数据，电话管理，并形成一个综合指数是令人鼓舞的。他们的结构效度证明了他们的相关性与社会人口特征和健康指标，复制现有的研究结果，以及他们的预测IADL和ADL功能与理论一致。
Decline in cognitive functioning and onset of cognitive impairment are potentially important predictors of elderly persons needing informal assistance and formal health care. This article describes the measures of cognitive functioning that were developed for the Asset and Health Dynamics Among the Oldest Old (AHEAD) study of some 6500 Americans aged 70 years and older. The study was designed to investigate the impact of health of disbursement of family and economic resources. Evaluation of the cognitive measures Bt terms of psychometric properties and missing data, telephone administration, and formation of an aggregate index is encouraging. Their construct validity is evidenced by their correlations with sociodemographic characteristics and health indicators that replicate existing findings as wed as by their prediction of IADL and ADL functioning that are consistent with theory.
