Telephone interviewing is increasingly being used to obtain data on health issues. Propertly 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.
电话访谈越来越多地被用于获取有关健康问题的数据。正确应用电话访谈可能会带来可观的成本效益，但必须仔细考虑调查设计、数据加权和分析，以避免主要的偏差来源。本研究是一项假设性练习，将采用面对面访谈方法从系统、自加权、多阶段、聚类的家庭区域样本中获得的健康估计值，与通过随机数字拨号和电子白页获得的假设人群样本进行比较。在对这些样本进行的假设分析中，对若干健康问题获得的总体健康估计值进行比较时，估计值的置信区间相互重叠。由于这些估计值在统计上没有显著差异，因此，精心策划、加权和分析得当的电话调查似乎是获取健康信息的一种成本较低的方式，然而，在使用这种方法时需谨慎。
