Quality management for telephone surveys in the context of mixed-mode studies

考虑到答复率不断下降，混合模式调查在人口调查中发挥着越来越大的作用，在这方面，电话调查极为重要：在混合模式调查中，电话调查既用于征聘阶段，也用于实际面谈。近年来，在德累斯顿工业大学和GESIS的DFG资助的项目中，可以获得对电话采访功能的重要见解。特别是，我们可以阐明在调查中同时使用固定和移动的电话、衡量答复质量、抽样和加权。然而，电话调查在方法上仍有许多悬而未决的问题。在这里，辅助数据分析将具有很大的价值。它应该分析项目合作伙伴的大量过程数据。该项目的目的是就混合模式调查中的抽样和电话调查实地工作的最佳设计提出合理的建议。这将是一个知识转移从学术研究调查机构在招标方面：研究CELLA1，CELLA2和移动的面板的经验将直接运行到应用程序合作伙伴的数据集的分析。通过这种方式，同时可以产生新的知识。我们可以从莱布尼茨社会科学研究所的工作中得出结论，该项目的这些成果非常受欢迎。在这方面，往往需要对电话调查提出透明的建议，但我们目前无法提供，因为还需要进一步的研究（如打算进行的研究）。

Mixed Mode Surveys play an increasing role in population surveys when considering declining response rates.In this context telephone surveys are of extreme importance: Within mixed mode surveys, they are used both for the recruitment phase and for the actual interviews. In recent years important insights into the functioning of telephone interviews could be obtained in DFG funded projects at the TU Dresden and GESIS. In particular, we could shed light on the parallel use of fixed and mobile phones in surveys, the measurement of response quality, the sampling and weighting. However, for telephone surveys there are still many open methodological questions. Here a secondary data analysis would be of great value. It should analyze the huge amount of process data of the project partners. The aim of the project is to give justified recommendations for sampling and for an optimal design of the fieldwork for telephone surveys in the context of mixed-mode surveys. This would be a knowledge transfer from academic research to survey institutions in terms of the tender: The experience of the studies CELLA1, CELLA2 and mobile panel would directly run into the analysis of the data sets of the application partners. This way at the same time new knowledge could be generated.That these results of the project were very much in demand, we can conclude from our work at Leibniz Institute for Social Sciences. Here often transparent recommendations for telephone surveys are required, which we currently cannot provide, because further research (such as the one intended) is still needed.
