Functional performance is a critical outcome to examine in dementia. The authors review some of the limitations of current research on functional performance and identify a conceptual framework for outcomes research. When considering conceptual frameworks to apply to functional assessment for outcomes research, five broad issues emerge: variability in definitions, an assumed equality between functional performance and capacity, measurement of global task abilities but not abilities for task components, lack of a contextual perspective, and use of a physical disability framework that excludes cognitive disability. When selecting assessment methods, researchers also must consider the implications of informant-based instruments and performance-based instruments. The authors also discuss a conceptual framework for evaluating current functional performance assessment instruments.
功能表现是痴呆症研究中一个关键的考察结果。作者回顾了当前功能表现研究的一些局限性，并确定了一个用于结果研究的概念框架。在考虑适用于结果研究功能评估的概念框架时，出现了五个广泛的问题：定义的可变性、功能表现与能力之间假定的等同性、对整体任务能力而非任务组成部分能力的测量、缺乏情境视角以及使用排除认知障碍的身体残疾框架。在选择评估方法时，研究人员还必须考虑基于知情者的工具和基于表现的工具的影响。作者还讨论了一个用于评估当前功能表现评估工具的概念框架。
