轻度功能障碍与老年人的早期认知功能下降有关，轻度认知障碍患者转化为痴呆的风险增加，但我们对这种下降的理解受到缺乏客观方法的限制。本研究评估了一个新的系统的可靠性和有效性，以代码的微妙的错误，对一个既定的基于性能的措施，日常行动和行动中断的理论模型的背景下，描述了初步的调查结果。在这里，45名老年人完成了自然行动测试（NAT）和神经心理学的措施。NAT性能编码的明显错误，微妙的行动困难进行了评分使用一种新的编码系统。计算评价者间信度系数。编码系统的有效性进行了评估，使用重复测量方差分析与NAT任务（简单与复杂）和错误类型（显性与微妙）作为组内因素。相关/回归分析进行了明显的NAT错误，微妙的NAT错误，和神经心理变量。微妙动作错误的编码是可靠和有效的，情景记忆崩溃预测微妙动作中断。结果表明，NAT可以客观地评估微妙的功能下降。针对情景记忆的治疗可能是最有效的解决老年早期功能障碍。
Mild functional difficulties have been associated with early cognitive decline in older adults and increased risk for conversion to dementia in mild cognitive impairment, but our understanding of this decline has been limited by a dearth of objective methods. This study evaluated the reliability and validity of a new system to code subtle errors on an established performance-based measure of everyday action and described preliminary findings within the context of a theoretical model of action disruption. Here 45 older adults completed the Naturalistic Action Test (NAT) and neuropsychological measures. NAT performance was coded for overt errors, and subtle action difficulties were scored using a novel coding system. An inter-rater reliability coefficient was calculated. Validity of the coding system was assessed using a repeated-measures ANOVA with NAT task (simple versus complex) and error type (overt versus subtle) as within-group factors. Correlation/regression analyses were conducted among overt NAT errors, subtle NAT errors, and neuropsychological variables. The coding of subtle action errors was reliable and valid, and episodic memory breakdown predicted subtle action disruption. Results suggest that the NAT can be useful in objectively assessing subtle functional decline. Treatments targeting episodic memory may be most effective in addressing early functional impairment in older age.
