Background Cognitive impairment is common among older people and is associated with increased morbidity and mortality. The main aim of this study was to evaluate the validity of the P ersian version of the A bbreviated M ental T est S core ( AMTS ) as a screening tool for dementia. Methods Data were obtained from a cross‐sectional study. One hundred and one older adults who were members of I ranian A lzheimer A ssociation and 101 of their siblings were entered into this study by convenient sampling. The Diagnostic and Statistical Manual of Mental Disorders , 4th edition, criteria for diagnosing dementia and the M ini‐ M ental S tate E xamination were used as the study tools. The gathered data were analyzed by the M ann– W hitney U ‐test, the K ruskal– W allis test, S pearman's rank correlation coefficient, and the r eceiver–operating characteristic. Results The AMTS could successfully differentiate the dementia group from the non‐dementia group. Scores were significantly correlated with Diagnostic and Statistical Manual of Mental Disorders diagnosis for dementia and M ini‐ M ental S tate E xamination scores ( P < 0.001). Educational level ( P < 0.001) and male sex ( P = 0.015) were positively associated with AMTS , whereas ( P < 0.001) was negatively associated with AMTS . Total C ronbach's α coefficient was 0.90. The scores 6 and 7 showed the optimum balance between sensitivity (99% and 94%, respectively) and specificity (85% and 86%, respectively). Conclusions The P ersian version of the AMTS is a valid cognitive assessment tool for older I ranian adults and can be used for dementia screening in I ran.
