FRIDAY 22 JULY 173Behavioral quesons in survey research do not control the context while economic lab experiments pose ques-ons regarding external validity. Our study combines both methodologies in order to answer substanve ques-ons. Polical behavior research usually relies in survey quesons measuring past behavior. This makes it difficultto address theorecal quesons regarding the effect of the specific context and individuals ’movaons.Therefore we designed an economic experiment that permied to control the environment and induce themovaons. Main independent variables were measured by a short version of the European Social Survey.4.4 Mobilise! Incorporang Mobile Phones in Survey Research IITo be held on July 22, 2011 from: 09:00 to 10:30, in room 318.Coordinated by:• Marek Fuchs - Darmstadt University of Technology, Germany• Femke De Keulenaer - Gallup Europe, Belgium• Robert Manchin - Gallup Europe, Belgium4.4.1 The effect of field period on response in a mobile phone surveyP. Vicente 1 , E. Reis 11 ISCTE-Lisbon University Instute, PortugalMobile phone ownership is approaching saturaon in Portugal as in many other European countries. Not surprisingly,survey companies are starng to make use of mobiles phones to collect survey data. Mobile phoneshave specific characteriscs that are disnct from other modes of data collecon – they are personal devices,carried at all mes and to all places – and as such can influence the representaon of various respondentsgroups and the quality of responses in a mobile phone survey.4.4.2 Pre-Call Validaon of Random Digit Dialing Cell Phone Numbers: A Field ExperimentT. Kunz 1 , M. Fuchs 11 Darmstadt University of Technology, GermanyThe present experiment is designed to test mechanisms which can be used to validate random digit cell phonenumbers prior to field work: (1) Cell phone number validaon services provide verificaon in real me byperforming a Home Locaon Register (HLR) lookup. (2) Text messaging services can also be used for cell phonenumber validaon by using a text message gateway and sending bulk text messages from the Internet to cellphones.4.4.3 Differenal call scheduling in dual frame telephone surveysF. De Keulenaer 1 , R. Manchin 11 Gallup Europe, BelgiumIt is well established that me-of-day and day-of-the-week are important factors to consider when calls arescheduled in telephone surveys. Calling schedules for landline surveys are generally skewed towards eveningand weekend calling since this is when most people are available at home. Research shows that many peoplehave their mobile phones on all day; as such, mobile phones provide a direct communicaon link to respondentsat virtually any me. Nevertheless, most mobile phone surveys use the same ”skewed” calling schedulesthat are typical of landline surveys. In this study, we want to explore how call scheduling in mobile phonesurveys can be opmized in order to increase contact and compleon rates. We will endeavor to answer thisqueson by analyzing contact history data of several landline, mobile phone and dual frame surveys conductedby Gallup in the past five years in many European countries...
