Experimental Mobile Phone Panel

欧洲和美国持续增长的纯手机费率要求改变电话调查方法。与此同时，仅使用移动电话的人口已经在一定程度上增长，忽视这一点将对固定电话调查结果的代表性产生致命后果。因此，已经制定并研究了解决这一问题的办法。这样的解决方案可以是(1)像几个东欧国家的闪存欧洲晴雨表研究已经做的那样，抽取纯移动电话样本)或(2)通过移动电话样本来补充固定电话样本，并借助双框架方法进行集成。这两种解决方案都需要在移动电话调查领域进行进一步研究，因为这是由实验移动电话小组完成的。第二阶段的实验手机面板项目旨在回答以下问题：(1)在德国，谁只使用手机？仅流动人口的社会人口、态度和行为特征是什么？由于只有流动人口，覆盖者的未来发展是什么？在传记转变过程中，手机是永久性的还是暂时的现象？(2)手机实际上是个人设备吗？共用手机的人占多大比例，与多少人共用？鉴于这种现象，应该如何适当地确定选择概率？使用双框架设计整合电话和手机子样本的适当方法是什么？(3)在手机调查中，后分层或倾向分数加权程序是否代表可靠和可行的单位无回答解决方案？在手机调查中，有哪些成功的策略可以减少无回应率？

Continuously growing mobile-only rates in Europe and the USA require a change telephone survey methodology. Meanwhile the mobile-only population has grown to an extent, that ignoring it would have fatal consequences forepresentativenes of landline telephone survey results. Therefore solutions to this problem have be developed and examined. Such solutions could be (1) drawing pure mobile phone samples as it is already done by Flash Eurobarometer studies in several East-European countries) or (2) complementing fixed-line telephone samples by mobile phone samples, integrated with the help of dual frame aproach. Both solutions require furtheresearch in the area of mobile phone surveys as it is done by Experimental Mobile Phone Panel. The second period of the Experimental Mobile Phone Panel project aims at answering the folowing questions:(1) Who is mobile-only in Germany? What are the socio-demographic, atitudinal and behavioural properties of the mobile-only population? What are future developments in coverageror due to the mobile-only population? Is a permanent condition or just temporary phenomenon during biographic transitions?(2) Are mobile phones in fact personal devices? What is the proportion of people sharing their mobilephone and with how many people are they sharing? Given this phenomenon, how shouldselection probabilities determined appropriately? What is the appropriate approach to integratelandline and mobile phone sub-samples using a dual frame design?(3) Do post-stratifications or propensity score weighting procedures represent reliable and practicable solutions to unit non-response in mobile phone surveys? What are sucesful strategies to reduce non-response in mobile phone surveys?
