Differential item functioning in the Mini-Mental State Examination in English- and Spanish-speaking older adults.
The purpose of this study was to determine if the Mini-Mental State Examination (MMS; M. F. Folstein, S. E. Folstein, & P. R. McHugh, 1975) demonstrates item bias with respect to measuring cognitive functioning of older Hispanics and non-Hispanics. Assessment of differential item functioning (DIF) of individual MMS items across 3 language/ethnicity groups (English test administration/non-Hispanic ethnicity, English test administration/Hispanic ethnicity, and Spanish test administration/Hispanic ethnicity) was performed by using a logistic regression procedure. Fifteen of the 26 MMS items were significantly related to total score and were shown to provide unbiased measurement across the 3 groups. Normative data are presented for older Hispanics (n = 365) and non-Hispanics (n = 388) on the raw MMS, a 15-item version in which items with significant DIF were eliminated, and a total score statistically adjusted for effects of education and age.
