Correlation between the 37-item mental test score and abbreviated 10-item mental test score by psychogeriatric day patients

Groups of organically and functionally mentally ill psychogeriatric day patients were assessed by the 37-item Roth-Hopkins test and the abbreviated ten-item Roth-Hopkins test. The scores correlated highly, correlation being equally good for both diagnostic groups. Among the functionally ill and the mild organically ill, scores improved between first and second test. The quicker, better tolerated ten-item test is a useful test of mental impairment for psychogeriatric patients in the community, as well as in institutional care.
