Cognitive decline is an important and well-documented health problem. The Mini-Cog, a simple cognitive function test, is recommended as a potential early cognitive screening tool. Kanagawa Prefecture, one of the largest prefectures in Japan, developed this self-testing application on a smartphone to enable a large number of residents to assess their cognitive function. This study aimed to verify the validity and reliability of the Mini-Cog.
Twenty men and 20 women aged 65-85 years were enrolled. Criterion-related validity of the method tested by professional staff was found to have an acceptable positive association. The test-retest reliability was lower than the clinically expected intraclass correlation coefficient value because of the inclusion of learning and order effects. If the Mini-Cog score of this application is low, the system is equipped with a function that advises the users on preventing cognitive decline, directing them to the appropriate services, and recommending visits to a medical institution. Therefore, the system can be used continuously as a tool for health behaviors and promotions.
认知能力下降是一个重要且有据可查的健康问题。Mini-Cog 是一种简单的认知功能测试，被推荐作为一种潜在的早期认知筛查工具。日本最大的县之一神奈川县开发了这款智能手机自测应用程序，以让大量居民能够评估自己的认知功能。本研究旨在验证 Mini-Cog 的有效性和可靠性。
共纳入 20 名 65-85 岁男性和 20 名女性。经专业人员测试的方法的效标关联效度显示出可接受的正相关。由于包含学习和顺序效应，测试-重测信度低于临床预期的组内相关系数值。如果该应用程序的 Mini-Cog 分数较低，系统会配备一项功能，建议用户预防认知能力下降，指导他们使用适当的服务，并建议他们去医疗机构就诊。因此，该系统可作为促进健康行为的工具持续使用。
