The aim of this study was to assess the psychometric properties of the Mini-Cog in Iranian older adults. It was a cross-sectional study; 50 older people with dementia and 50 without dementia who matched for age, gender, and education entered the study. The diagnostic and statistical manual of mental disorders criteria for dementia were used as gold standard. A battery of scales included the abbreviated mental test score (AMTS), the Geriatric Depression Scale, and the Mini-Cog was performed. Validity and reliability of the Mini-Cog determined using the Pearson product-moment correlation coefficient (Pearson's r), Cronbach's alpha, and Receiver Operating Characteristic (ROC) curve analysis. The Persian version of Mini-Cog showed a good inter-rater reliability ( K = 0.76, p < .01) and a positive concurrent validity ( r = 0.39, p < .01) with the AMTS. The sensitivity and specificity were 88% and 62.8%, respectively, using the original cutoff point of 2. The findings showed that the Persian version of Mini-Cog have an acceptable sensitivity, specificity, and substantial overall agreement with the AMTS.
本研究的目的是评估简易认知评估量表（Mini-Cog）在伊朗老年人中的心理测量特性。这是一项横断面研究；50名患有痴呆症的老年人和50名年龄、性别和教育程度相匹配的非痴呆老年人参与了研究。《精神障碍诊断与统计手册》中痴呆症的诊断标准被用作金标准。进行了一系列量表测试，包括简易精神状态检查表（AMTS）、老年抑郁量表和Mini-Cog。使用皮尔逊积差相关系数（Pearson's r）、克朗巴赫α系数和受试者工作特征（ROC）曲线分析来确定Mini-Cog的有效性和可靠性。Mini-Cog的波斯语版本显示出良好的评分者间信度（K = 0.76，p < 0.01），并且与AMTS具有正的同时效度（r = 0.39，p < 0.01）。使用原始截断值2时，敏感性和特异性分别为88%和62.8%。研究结果表明，Mini-Cog的波斯语版本具有可接受的敏感性、特异性，并且与AMTS总体一致性良好。
