An internet-based method of selecting control populations for epidemiologic studies.
Identifying control subjects for epidemiologic studies continues to increase in difficulty because of changes in telephone technology such as answering services and machines, caller identification, and cell phones. An Internet-based method for obtaining study subjects that may increase response rates has been developed and is described. This method uses information from two websites that, when combined, provide accurate and complete lists of names, addresses, and listed phone numbers. This method was developed by use of randomly selected streets in a suburb of Salt Lake City, Utah, in June 2005.
