This study investigated the relationship between measures of executive functioning and both observed and self-reported functional ability. It was hypothesized that performance on a direct assessment of functional ability would have a stronger correlation with performance on measures of executive functioning than a self-report measure of functional ability. Results supported the hypothesis, indicating that self-report measures may not be sensitive to early decline in functional ability. Results also provide evidence to support the use of measures of executive functioning to detect early decline in functional ability that otherwise may not be detected by the typical self-report measures used in clinical settings. While lack of insight into functional deficits has been demonstrated in the literature in older adults with dementia, this study demonstrated lack of insight in a non-demented, community dwelling sample of older adults.
本研究调查了执行功能测量与观察到的和自我报告的功能能力之间的关系。研究假设是，与功能能力的自我报告测量相比，功能能力直接评估的表现与执行功能测量的表现具有更强的相关性。结果支持了这一假设，表明自我报告测量可能对功能能力的早期下降不敏感。结果还提供了证据，支持使用执行功能测量来检测功能能力的早期下降，否则这些下降可能无法通过临床环境中使用的典型自我报告测量检测到。虽然文献中已证明患有痴呆症的老年人对功能缺陷缺乏洞察力，但本研究在非痴呆的社区居住老年人样本中也证明了缺乏洞察力。
