The purpose of this study was to reveal inter- and intra-rater reliability of the detailed evaluation of cognitive function by assistive robot for older adults.
We investigated the inter-rater and test-retest reliability. Neurobehavioral Cognitive Status Examination was conducted twice for each participant using an assistive robot and the examiner respectively (Experiment 1). The order of these two tests was randomly selected and the interval between them was 1 week. In Experiment 2, we investigated the test-retest reliability of the first robot test and this additional robot test was conducted approximately 6 weeks after Experiment 1.
Fifty-one (13 men and 38 women, mean age: 80.5 ± 5.6 years) participants went through Experiment 1 and 29 of those (eight men and 21 women, mean age: 80.4 ± 4.8 years) completed Experiment 2. In Experiment 1, the interclass coefficient (ICC) in orientation was in the high range and its Cronbach's α was 0.919, rated as excellent internal consistency. On the other hand, other items did not show positive results. In Experiment 2, the ICCs in orientation, attention, and repetition were in the adequate range, while other items showed marginal or low range.
Orientation was supposed to be utilised for figuring out initial symptoms of dementia. In the future, as robot functions become more high-tech, a partner robot might be able to measure the symptoms and severity of dementia.
本研究的目的是揭示辅助机器人对老年人认知功能进行详细评估时评分者间和评分者内的可靠性。
我们调查了评分者间信度和重测信度。使用辅助机器人和检查者分别对每位参与者进行两次神经行为认知状态检查（实验1）。这两次测试的顺序随机选择，间隔为1周。在实验2中，我们调查了首次机器人测试的重测信度，该额外的机器人测试在实验1后约6周进行。
51名参与者（13名男性和38名女性，平均年龄：80.5±5.6岁）完成了实验1，其中29名（8名男性和21名女性，平均年龄：80.4±4.8岁）完成了实验2。在实验1中，定向方面的组内相关系数（ICC）处于较高范围，其Cronbach's α为0.919，评定为具有出色的内部一致性。另一方面，其他项目未显示出阳性结果。在实验2中，定向、注意力和复述方面的ICC处于适当范围，而其他项目显示为临界或低范围。
定向可用于识别痴呆的初始症状。未来，随着机器人功能变得更加高科技，伴侣机器人或许能够测量痴呆的症状和严重程度。
