dc.description.abstract	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 alpha 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.	en_US
