20.500.12556/RUL-22458 Contingent versus unconditional incentives in www-studies Five experiments examined how participation in WWW-studies was influenced by framing the reception of an incentive as contingent on the completeness of the submitted questionnaire. Four experiments were carried out in a university-based online panel and one in a market research online panel. Four times the incentive was a prize draw and once it was a personal gift. In each experiment, two conditions were contrasted: one group received an e-mail invitation mentioning that all participants are eligible for the incentive (= unconditional incentive), whereas the other group was told that only those participants who answer every question in the questionnaire would receive the incentive (= contingent incentive). Dependent measures were response rate, retention rate, number of omitted closed-ended items, length of answers to open-ended questions, and stereotypical answering of grid-like question batteries. There were no significant effects. The results of the individual experiments were then meta-analytically aggregated. It was revealed that contingent relative to unconditional incentives decrease response to a study, while at the same time the sparser data are not compensated for by a superior data quality or retention. true false false Angleški jezik Neznan jezik Delo ni kategorizirano 2014-07-11 14:26:41 2014-07-11 14:26:41 2022-06-02 03:50:32 0000-00-00 00:00:00 2005 0 0 Str. 1-14 no. 1 Vol. 2 2005 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 303 1854-0023 24321629 http://mrvar.fdv.uni-lj.si/pub/mz/mz2.1/goritz.pdf 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=22458 Fakulteta za družbene vede Metodološki zvezki 0 0 0
