The proportion of web survey responses submitted from mobile devices such as smartphones is increasing steadily. This trend presents new methodological challenges because mobile responses are often associated with increased breakoffs, which, in turn, can increase nonresponse bias. Using data from a survey of college students with more than 20,000 respondents, response patterns are examined to identify which days and times the survey invitation and reminder emails were most likely to produce nonmobile responses. The findings provide guidance on the optimal timing for recruiting college student sample members via email to reduce their likelihood of responding from a mobile device, and potentially, breaking off.

从诸如智能手机之类的移动设备提交的网络调查回复的比例正在稳步增长。这种趋势提出了新的方法挑战，因为移动响应通常与中断增加有关，而中断又会增加无响应偏差。使用来自对超过20,000名受访者的大学生进行的调查数据，调查了答复模式，以确定调查邀请和提醒电子邮件最有可能产生非移动性答复的日期和时间。研究结果为通过电子邮件招募大学生样本成员的最佳时机提供了指导，以减少他们从移动设备做出回应的可能性，甚至有可能中断。
