Abstrakt:	Background: The six-item cognitive impairment test (6CIT) is a brief cognitive screening tool that can be administered to older people in 2-3 min. Objective: To adapt the 6CIT for the European Portuguese and determine its psychometric properties based on a sample recruited from several contexts (nursing homes; universities for older people; day centres; primary health care units). Method: The original 6CIT was translated into Portuguese and the draft Portuguese version (6CIT-P) was back-translated and piloted. The accuracy of the 6CIT-P was assessed by comparison with the Portuguese Mini-Mental State Examination (MMSE). A convenience sample of 550 older people from various geographical locations in the north and centre of the country was used. Results: The test-retest reliability coefficient was high (r = 0.95). The 6CIT-P also showed good internal consistency (α = 0.88) and corrected item-total correlations ranged between 0.32 and 0.90. Total 6CIT-P and MMSE scores were strongly correlated. The proposed 6CIT-P threshold for cognitive impairment is ≥10 in the Portuguese population, which gives sensitivity of 82.78% and specificity of 84.84%. The accuracy of 6CIT-P, as measured by area under the ROC curve, was 0.91. Conclusion: The 6CIT-P has high reliability and validity and is accurate when used to screen for cognitive impairment.
