To validate the Instrumental Activities of Daily Living in Greek, 44 men (M age=70.5 yr., SD=7.2) and 58 women (M age= 68.4, SD=9.2), outpatients of memory clinics, were studied. Sex differences in the item responses were evaluated. Reliability assessed as Cronbach alpha was .84, while validity was assessed by correlation of .77 with the Mini-Mental State Examination. 21 men and 20 women had moderate to severe dementia, with Mini-Mental State Examination scores <20. The results show that this Greek language version can be effectively used in Greece.
