Results are described from four epidemiologic studies in the United States which used random digit dialing in over 30,000 households to identify controls from the general population for use in case-control studies. Methods and problems in telephone sampling are discussed. It is concluded that if complete population rosters are unavailable and if the population to be sampled has the high rates of telephone ownership typical of much of the United States, telephone-based sampling can yield a nearly random sample of the individuals in a population, often at much less expense than can dwelling-based sampling.
本文介绍了美国四项流行病学研究的结果，这些研究通过随机数字拨号法，对超过30000户家庭进行调查，以便从普通人群中识别出对照组，用于病例对照研究。文中还讨论了电话抽样的方法和问题。研究得出结论：如果没有完整的人口名单，并且所要抽样的人群拥有电话的比例很高，就像美国大部分地区那样，那么基于电话的抽样方法能够产生一个几乎随机的人群样本，而且其成本往往比基于住所的抽样方法低得多。
