OBJECTIVES To assess the psychometric properties of the Peruvian version of the Rowland Universal Dementia Assessment Scale (RUDAS-PE) to discriminate controls from patients with mild cognitive impairment (MCI) and early dementia (ED) in a population with a mid-level education. METHODS A total of 133 patients from a memory clinic were administered the RUDAS-PE, INECO Frontal Screening, Addenbrooke's Cognitive Examination, and Mini-Mental State Examination. Results were compared against a neuropsychological evaluation (gold standard). Validity measures, internal consistency, and concurrent validity were calculated. RESULTS Cronbach's α was 0.68; Pearson's ratio was 0.79 (P < .01). The area under the receiver-operating characteristics curve of the RUDAS to discriminate between ED and MCI was 89.0% (optimal cutoff at <21), whereas between MCI and controls, it was 99.0% (optimal cutoff at <24). CONCLUSIONS The RUDAS-PE has acceptable psychometric properties performing well in its ability to discriminate controls from patients with MCI and ED.

RUDAS 在秘鲁利马中等教育水平患者中的验证。


目的 评估秘鲁版罗兰通用痴呆评估量表 (RUDAS-PE) 的心理测量特性，以区分中等教育人群中轻度认知障碍 (MCI) 和早期痴呆 (ED) 患者的对照组。方法 对来自记忆诊所的总共 133 名患者进行了 RUDAS-PE、INECO 额叶筛查、阿登布鲁克认知检查和简易精神状态检查。将结果与神经心理学评估（金标准）进行比较。计算有效性测量、内部一致性和同时有效性。结果 Cronbach’s α 值为 0.68；皮尔逊比率为 0.79 (P < .01)。区分 ED 和 MCI 的 RUDAS 接受者操作特征曲线下面积为 89.0%（最佳截止值为 <21），而 MCI 和对照之间的面积为 99.0%（最佳截止值为 <24）。结论 RUDAS-PE 具有可接受的心理测量特性，在区分对照组和 MCI 和 ED 患者的能力方面表现良好。
