160 THURSDAY 21 JULY3.40.1 Mobile-only – Persistent status or passage in the life course? Results from a Mobile Phone PanelStudyB. Busse 1 , C. Neuert 1 , M. Fuchs 11 Darmstadt University of Technology, GermanyIn recent years the mobile-only populaon has gained more and more importance for survey research since ithas increased consistently in most industrialized countries. In some European countries like Finland, Swedenor the Czech Republic mobile phone penetraon rates have exceeded 90 percent; at the same me landlinepenetraon rates have declined. Thus, mobile-only rates have surpassed 30 percent in many countries. Asknown from the literature (e.g. Blumberg and Luke 2010; Fuchs, 2008; Ehlen and Ehlen, 2007) mobile-onlysdiffer from the landline populaon as they are young, single, male and either belonging to a low-income or ahigh-income segmentaon. Consequently it is necessary to complement tradional landline telephone surveymethods with mobile phone survey in order to cover the mobile-onlys in telephone surveys...3.40.2 Survey Response via Mobile Phone: A Total Survey Error PerspecveP. Lynn 1 , O. Kaminska 11 University of Essex, United KingdomThe search for cost effecve survey designs with high coverage and high response increasingly leads surveypraconers to consider data collecon via mobile phones, typically as part of a mixed-mode design. However,quality of measurement is also important. To conduct high quality surveys via mobile phone one needs tounderstand what factors may influence responses to survey quesons in this mode and how, if at all, thesefactors may differ from other modes.3.40.3 Are dual users from landline and mobile samples the same?A. Alanya 1 , F. De Keulenaer 1 , R. Manchin 11 Gallup Europe, BelgiumDual frame (landline and mobile phone) samples are increasingly used in telephone surveys; there is, however,no consensus on the best design for such surveys. Integrang mobile and landline samples may beaccomplished in two ways: (1) segmented designs which screen out respondents with landlines from the mobilesample (i.e. only mobile-only are interviewed by mobile phone) and (2) overlapping or ”full” dual framedesigns which include dual users from the mobile and landline samples.3.40.4 Reaching the Young and the Mobile - Reducing the CATI Landline Telephone Bias using the Dual-Frame Approach in a large Naonal Survey in SwitzerlandS. Klug 2 , D. Müller 11 IBSF Instut für Begleit- und Sozialforschung Zürich, Switzerland; 2 DemoSCOPE, SwitzerlandWhile the availability of people through households with landline telephones declined over the last years theusage of randomly generated mobile telephone numbers to cover up for this lack of representaveness hasnot yet been fully implemented as a standard approach in social and market research surveys.DemoSCOPE has been awarded the contract for a mul-year large naonal survey (Connuous Rolling Surveyof Addicve Behaviours and Related Risks, CoRolAR) for the Schweizerische Eidgenossenscha, Bundesamt fürGesundheit (BAG), Bern, on behalf of the IBSF Instut für Begleit- und Sozialforschung with 11’000 interviewsannually using the dual-frame approach.3.41 The Quality of Longitudinal Survey Data: Measurement Error & Arion VTo be held on July 21, 2011 from: 16:00 to 17:30, in room 415.Coordinated by:
