Stroke is a leading cause of disability for adults. Several studies confirm cognitive impairment in persons following stroke. Every stroke patient should have rapid access to cognitive screening and evaluation. In this study, Rasch analysis was used to determine the suitability of the telephone version of the Mini-Mental State Examination (MMSE) in screening for cognitive impairment in persons with stroke. The specific objectives were to determine the range of difficulty represented by the items of the telephone version of the MMSE, to identify the hierarchy of item difficulty and to compare the French and English versions of the test. Rasch analysis was conducted on data obtained from 267 persons with first-ever stroke who completed the telephone version of the MMSE at 1 month post stroke. Results indicated that the telephone version of the MMSE did not target the full range of the persons' cognitive ability, especially for those with 'higher' cognitive ability. The item difficulty ranged from (-3.258 to 2.585 logits), and the average person mean (2.351 logits) was greater than the average item mean set at 0. The test was easy for most persons; the majority were situated above the mean item difficulty. Fit of the items to the Rasch model is discussed with alternate scoring methods suggested.
