The current study aimed to validate the Performance Validity Test Coin in Hand-Extended Version (CIH-EV) in groups of healthy older adults and older adults with dementia.
Using an analog simulation paradigm, the healthy control group and the clinical group were instructed to perform to the best of their ability, whereas the feigning older adults were instructed to simulate a memory deficit to obtain allowance, financial aid, or early retirement.
Results showed that the control and clinical groups performed more optimally than the feigning group, although the clinical group had superior response times. The CIH-EV was insensitive to sociodemographic variables and neurocognitive functioning in all groups, demonstrated good convergent validity with other performance validity measures, and showed a reduced rate of false positives.
This study corroborates the CIH-EV's effectiveness in detecting the simulation of cognitive deficits in healthy older adults and older adults with dementia.
本研究旨在验证硬币在手伸展版本（CIH-EV）在健康老年人和老年痴呆症患者中的表现效度。
使用模拟模拟范式，健康对照组和临床组被指示尽最大能力执行任务，而伪装老年人则被指示模拟记忆缺陷以获得津贴、经济援助或提前退休。
结果表明，尽管临床组的反应时间更好，但对照组和临床组的表现比伪装组更优。CIH-EV 对所有组的社会人口统计学变量和神经认知功能不敏感，与其他表现效度测量具有良好的收敛效度，并且假阳性率较低。
本研究证实了 CIH-EV 在检测健康老年人和老年痴呆症患者认知缺陷模拟方面的有效性。
