Objectives: The goal of the present study was to assess the psychometric properties of the Persian version of Rey Auditory-Verbal Learning Test (RAVLT) in the elderly population. Method: 250 normal elderly individuals and 100 elderly individuals with Alzheimer’s dementia, aged between 60 and 80 who were selected using stratified-randomized sampling, were evaluated using Mini-Mental State Examination, RAVLT, and DSM-IV diagnostic criteria. Results: In determining convergent validity, a positive significant correlation was revealed between the four parts of RAVLT (sum, immediate and delayed recall and recognition) and the logical sub test of Wechsler Memory Scale (p< 0.001, r= 0.346). By comparing the test scores between the normal and Alzheimer’s group, discriminant validity analysis showed significant difference of their data in all parts of the test (p< 0.001). Roc curve exhibited a sensitivity of more than 89% and a specificity higher than 81% (p<0.001), and the cut-off points of 2.5 to 6.5 were determined with U-Dense formula for different parts of the test. Conclusion: The Persian version of the RAVLT has good validity and reliability. Also, based on the determined cut-off points, it can be used to evaluate and interpret the situation of short term memory and learning performance in the elderly, and for the  identification of individuals with Alzheimer’s dementia.
