摘要:
The distribution of total Mini-Mental State Examination (MMSE) scores, individual items, and groups of items were studied in French elderly community residents from a random sample of 2727 subjects. Serial sevens, recall three objects, and copy pentagons had the lowest percentage of correct responses, while orientation to place, naming two objects, and three objects registration had the highest percentage of correct responses. The structure of correlation of the items was studied using Principal Components Analysis. The projection of the items on the first axis reflects the tendency of the items to vary in the same direction and is compatible with the fact that the MMSE items are all indicators of the same concept: cognitive performance. The second and third axes identify clusters of highly correlated variables and provide support for the internal validity of the MMSE score for a French population. The full MMSE score seems to be a valid instrument for the evaluation of cognitive performance in community-based elderly residents.
