Landline telephone surveys have been used for several decades to generate critical knowledge about consumer confidence, health conditions, political attitudes, and other characteristics of the American public. The coverage provided by this methodology is rapidly declining due to widespread adoption and, in many cases, substitution of mobile (cell) phones over landlines. In order to address this problem, survey researchers have begun supplementing landline surveys with samples of mobile phone numbers. The error properties of mobile phone surveys, particularly with respect to nonresponse and measurement, are largely unknown. Researchers have limited knowledge as to why some people answer surveys on their mobile phone but others do not. It is also an open question as to whether people respond less accurately on a mobile phone as compared to a landline. The potential to reach people outside the home or engaged in an activity that distracts from the task of responding could result in respondents taking more cognitive shortcuts and providing less accurate data relative to a landline interview. These dynamics could also reduce the reliability of survey estimates and, for some measures, even change the mean of the response distribution. This proposal details an innovative study that will address these gaps in the literature. A repeated-measures design will be used to gain insights into individual-level mechanisms of nonresponse to alert researches to statistics at greatest risk of nonresponse bias. Randomization of subjects to phone type (mobile/landline) will facilitate testing for differential use of cognitive shortcuts in mobile phone versus landline interviews. The randomization step used in this experiment overcomes a critical confound that limits previous studies. This research will generate much-needed knowledge about the quality of data from mobile phone surveys. This knowledge will inform data collection decisions made by researchers who produce statistics about the American public.

座机电话调查已被使用了几十年，以产生有关消费者信心，健康状况，政治态度以及美国公众的其他特征的批判性知识。 由于采用广泛的采用，这种方法提供的覆盖范围正在迅速下降，并且在许多情况下，移动电话（Cell）手机替代了座机。为了解决这个问题，调查研究人员已经开始补充座机调查，其中包括手机号码的样本。手机调查的误差属性，尤其是在无响应和测量方面的错误属性，在很大程度上尚不清楚。 研究人员知道为什么有些人在手机上回答调查，而另一些人则没有了解。 与座机相比，人们在手机上是否准确响应的响应率较低，这也是一个悬而未决的问题。 接触家庭外的人们或从事一项分散注意力的活动的潜力可能会导致受访者采取更多的认知快捷方式，并相对于座机访谈提供较少准确的数据。 这些动力学还可以降低调查估计的可靠性，甚至在某些措施中，甚至改变了响应分布的平均值。 该建议详细介绍了一项创新的研究，该研究将解决文献中的这些差距。 重复测量设计将用于获得对无响应的个体级机制的见解，以提醒研究对统计的最大风险无响应偏见的风险。 随机对电话类型（移动/固定电话）的随机化将有助于测试手机与固定电话访谈中认知快捷方式的不同使用。 该实验中使用的随机步骤克服了限制先前研究的关键混杂。 这项研究将产生有关手机调查数据质量的急需知识。 这些知识将为您提供有关美国公众统计数据的研究人员做出的数据收集决策。
