English title: Comparison of three survey modes
Author(s): S. Laaksonen - Markku Heiskanen -
Type: Report, working paper
The paper compares the success of face-to-face, phone and web data collection modes. The survey designs are as identical as possible. Our application area, crime victimisation, is demanding in many ways, not least because the sensitiveness of the questions varies. Our research questions, respectively, are twofold. First, we assess the mode effects from the point of view of their frame coverage on one hand, and non-response, on the other. We exploit this analysis for developing ideal adjusted sample weights in order to compare differences in measurement. In the second phase, our standpoints are that the mode that secures better the secrecy for the respondent will produce higher victimisation prevalence, and the differences between the modes are larger when more sensitive questions are asked. Our results show that sensitive questions were not working well in telephone interviewing. It seems that the representativity of surveys depends on several factors, not for instance only on a high response rate.
