在随机数字拨号（RDD）全国电话调查中，联系和合作率下降，引起了人们对这种研究得出的估计数的有效性的严重关切。虽然20世纪90年代的研究表明，无应答偏倚相对较小，但应答率自那时以来持续下降。目前的研究复制了1997年的方法实验，该实验将采用皮尤研究中心通常方法的“标准”5天调查结果与在更长的实地调查期间进行的“严格”调查结果进行了比较，并实现了显着更高的响应率。与1997年的研究一样，几乎没有迹象表明，在所获得的答复率范围内的单位不答复会严重威胁调查估计数的质量。在84个可比较项目中，有77个项目的调查结果在统计上没有区别。虽然“严谨”的研究受访者往往不太参与政治，但他们在其他问题上并没有表现出一贯的不同行为或态度。在样本构成方面，标准调查与美国人口普查和其他大型政府调查对大多数变量的估计密切一致。我们扩展了对无应答的分析，包括与最难接触的受访者和在完成之前终止访谈的受访者的比较。
Declining contact and cooperation rates in random digit dial (RDD) national telephone surveys raise serious concerns about the validity of estimates drawn from such research. While research in the 1990s indicated that nonresponse bias was relatively small, response rates have continued to fall since then. The current study replicates a 1997 methodological experiment that compared results from a "Standard" 5-day survey employing the Pew Research Center's usual methodology with results from a "Rigorous" survey conducted over a much longer field period and achieving a significantly higher response rate. As with the 1997 study, there is little to suggest that unit nonresponse within the range of response rates obtained seriously threatens the quality of survey estimates. In 77 out of 84 comparable items, the two surveys yielded results that were statistically indistinguishable. While the "Rigorous" study respondents tended to be somewhat less politically engaged, they did not report consistently different behaviors or attitudes on other kinds of questions. With respect to sample composition, the Standard survey was closely aligned with estimates from the U.S. Census and other large government surveys on most variables. We extend our analysis of nonresponse to include comparisons with the hardest-to-reach respondents and with respondents who terminated the interview prior to completion.
