META-ANALYSIS ON RESPONSE RATES IN WEB SURVEYS Apologies for cross-posting. The WebSM research group (http://www.websm.org) is working on a meta-analysis to compare response rates in Web-based survey to rates in other survey modes. We already searched relevant scientific journals and conferences proceedings for relevant publications. But we are aware that we might miss important reports and articles. That is why we ask for your help. Please send us references and papers reporting on studies where data from a Web-based survey were compared to data from other survey modes. We are interested in the studies having following characteristics: (1) One of the survey modes used should be a Web-based survey, i.e. a survey where a survey questionnaire on the Web was used for gathering responses from respondents. (2) Data from the Web-based survey should be compared to data from one or more other survey modes (e.g. email survey, mail survey, telephone survey, face-to-face survey, fax survey, etc.). Comparable samples should be used in both (or all) modes. The use of split-sample experimental design is preferable. (3) Data on response rates from the Web and the other survey mode(s) used should be available. As an incentive for your help, we will send you a copy of our final report, and acknowledge your help in the report! Papers in English, German, French, and Italian are welcome. Our contact e-mail address: katja.lozar-manfreda@fdv.uni-lj.si Snail-mail: Katja Lozar Manfreda, Faculty of Social Sciences, University of Ljubljana, Kardeljeva ploscad 5, 1000 Ljubljana, Slovenia. P.S. Papers and reports that you will send us will not be published on the WebSM site (unless you explicitly request it). They will be used exclusively for the purposes of the meta-analysis. ************************************************************** Lozar Manfreda, Katja, PhD Assistant Professor Faculty of Social Science, University of Ljubljana Kardeljeva ploscad 5, 1000 Ljubljana, Slovenia Tel. +386 1 5805 284 Fax. +386 1 5805 101 Email: katja.lozar-manfreda@fdv.uni-lj.si, katja@ris.org Methodology of Web surveys: www.websm.org Faculty of Social Sciences: www.fdv.uni-lj.si Research on Internet in Slovenija: www.ris.org
