Research teams of Indiana University School of Medicine and University of Ibadan College of Medicine have established a collaborative study to determine the prevalence and incidence rates of Alzheimer's disease (AD) and other dementing disorders in elderly community-dwelling African Americans in Indianapolis and Yoruba in Ibadan, Nigeria. The purpose of this paper is to describe the design, the samples, and field work, and to report on the performance of the Community Screening Interview for Dementia (CSI"D") in the first phase of the prevalence study. Screening interviews were conducted with a random sample of 2212 African Americans age 65 years old and older in Indianapolis, and a sample of 2494 Yoruba age 65 years and older living in Ibadan. The CSI"D" contains a cognitive assessment with the subject and information about activities of daily living from a relative. When logistic regression models were used to predict dementia at both sites with age, sex, education, and cognitive score as predictors, the addition of relative score as a predictor in the models significantly improved the fit of the models (χ2 = 36.67, p<0.0001 for Indianapolis and χ2 = 13.81, p = 0.0002 for Ibadan). Sensitivity and specificity of the CSI"D" for both sites combined were 87.02% and 83.12% respectively (standard error 6.76%, 0.57%).
