Although random digit dialing (RDD) is an accepted and commonly used method of sampling populations for controls in case-control studies, there have been surprisingly few attempts to compare the accuracy of RDD with that of the best traditional alternative, i.e., household area surveys.
The aim of the present study was to compare a variety of characteristics of control subjects selected by RDD and area survey methods.
All data were gathered through in-person interviews of both types of control subjects.
The area survey identified a population-based sample of 20-to 79-year-old residents of two Washington State counties in 1978 and 1979.
