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 ( < .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.
目的
评估罗威（Rowland）普遍失智评估量表（RUDAS-PE）秘鲁版本的心理计量特性，以区分教育程度中等的人群中轻度认知障碍（MCI）和早期失智症（ED）患者与正常对照者。
方法
共有来自记忆门诊的 133 名患者接受了 RUDAS-PE、INECO 额叶筛查、阿登布鲁克认知测验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。计算了效度指标、内部一致性和同时效度。
结果
克朗巴赫α系数为 0.68；皮尔逊相关系数为 0.79（<0.01）。RUDAS 区分 ED 和 MCI 的受试者工作特征曲线下面积为 89.0%（最佳截断值<21），而区分 MCI 和对照组的曲线下面积为 99.0%（最佳截断值<24）。
结论
RUDAS-PE 具有可接受的心理计量特性，在区分 MCI 和 ED 患者与正常对照者方面表现良好。
