Despite their limitations, mental status tests and self/proxy reports of instrumental activities of daily living (IADL) are often used to predict functional competence. In contrast, the Assessment of Motor and Process Skills (AMPS) is a direct observational assessment of IADL competence. Sixty-four community-dwelling elderly (20 Alzheimer's disease [AD] patients and 44 nondemented) were assessed with the AMPS, the Mini-Mental State Examination (MMSE), and the Older Americans Resources and Services (OARS)-IADL. Performance on all three assessments was significantly lower for the AD sample. The MMSE did not correlate significantly with the AMPS motor ability measures but it correlated modestly with the AMPS process ability measures. The OARS-IADL correlated significantly with the AMPS motor ability measure for the nondemented sample alone. Although mental status and self/proxy assessments provide some insight into individuals' IADL competence, direct observation of IADL task performance provides additional information regarding the subtle process and motor skills changes that occur in progressive dementing conditions.
尽管存在局限性，但精神状态测试以及日常生活工具性活动（IADL）的自我/代理报告常被用于预测功能能力。相比之下，运动与过程技能评估（AMPS）是对IADL能力的直接观察评估。对64名居住在社区的老年人（20名阿尔茨海默病[AD]患者和44名非痴呆患者）进行了AMPS、简易精神状态检查表（MMSE）以及美国老年人资源与服务（OARS）-IADL评估。AD样本在所有三项评估中的表现均显著更低。MMSE与AMPS运动能力测量指标无显著相关性，但与AMPS过程能力测量指标有适度相关性。仅在非痴呆样本中，OARS-IADL与AMPS运动能力测量指标显著相关。尽管精神状态和自我/代理评估能提供一些关于个体IADL能力的见解，但对IADL任务表现的直接观察能提供有关在进行性痴呆病症中发生的细微过程和运动技能变化的额外信息。
