电话访谈越来越多地被用来获取有关炉灶问题的数据。正确应用电话访谈可能会带来相当大的成本效益，但在调查设计、数据加权和分析中必须仔细考虑，以避免主要的偏见来源。本研究是一项假设性练习，比较使用面对面访谈方法对系统、自加权、多阶段、集群、区域家庭样本的健康估计与通过随机数字拨号和电子白页获得的假设样本。在对这些样本的假设分析中针对许多健康问题获得的人口健康估计值进行比较时，估计值的置信区间重叠。由于估计值在统计上没有显着差异，因此精心策划、适当加权和分析的电话调查似乎是获取健康信息的一种较便宜的方式，但是，使用这种方法时需要谨慎。
Telephone interviewing is increasingly being used to obtain data on hearth issues. Properly applied telephone interviewing may have considerable cost benefits, but careful thought has to be put into the design of surveys, weighting and analysis of data to avoid major sources of bias. This study is a hypothetical exercise comparing health estimates from a systematic, self-weighting, multistage, clustered, area sample of households using a face-to-face interview method, with hypothetical samples of people obtained from Random Digit Dialling and Electronic White Pages. In a comparison of the population health estimates obtained for a number of health problems in a hypothetical analysis of these samples, the confidence intervals for the estimates overlapped. Since the estimates are not statistically significantly different, it appears that well-planned, appropriately weighted and analysed telephone surveys can be a less expensive way of obtaining health information, however, some caution is expressed in using this method.
