Abstract

Abstract: This validation study is discriminant and concurrent, with the Bayer-Activities of Daily Living (Bayer-ADL) tool among the Iranian elderly dementia illiterate and literate. The tools Bayer-ADL, Global Deterioration Scale (GDS), Mini Mental State Examination (MMSE), ADL-Barthel, and instrumental activities of daily living (IADL) were applied to find Bayer-ADL correlations in 311 dementia outpatients that were ≥60 years old. The Iranian version Bayer-ADL scores between illiterate and literate dementia elderly, based on GDS, observed good discrimination values (0.923 sensitivity and 0.750 specificity) in illiterate people, and excellent discrimination values were achieved (sensitivity 0.919 and 0. 986 specificity) in literate dementia elderly. The suggested cutoff points were 1.79 for illiterate and for the Iranian literate dementia elderly 1.82, based on GDS. Both forms (24 and 25 items) of Bayer-ADL were correlated to GDS, ADL, and IADL. Bayer-ADL is a valid tool to distinguish physical dysfunction between illiterate and literate of the Iranian dementia elderly; however, some revisions in the components are needed for the illiterate elderly. Generally, the findings presented in the Iranian version Bayer-ADL could be useful to both clinical purpose and international studies.
