Annotation	Lawton and Brody's 8-item Instrumental Activities of Daily Living (IADL) Scale is used often with older patients but scored in several different ways. The authors scored the IADL with seven popular procedures ranging from relatively simple to complex (Guttman scores, summed and Resch scores, from dichotomous, trichotomous, and polytomous items) in a sample of 231 rural older people from the American Midwest. They compared the IADL scales' prediction of concurrent cognitive functioning, depressive symptoms, psychosocial functioning, and health care use (medications, outpatient visits, inpatient days). Validity coefficients ranged from small to large among outcome variables but were high;ly consistent across IADL scoring procedures. Consequently, researchers and clinicians may prefer to use simple IADL screening procedures with this population. (RH).
