Abstract Altogether 3 experiments were conducted: one was carried out in a commercial online panel and the other two in a university online panel. It was examined whether the amount of item nonresponse could be reduced by framing the reception of an incentive as being contingent on the completeness of the submitted questionnaire. In each experiment two conditions were contrasted: Group 1 received an invitation e-mail that mentioned that XY will be raffled among all participants of the study, whereas group 2's otherwise identical e-mail read that XY will be raffled only among those participants who completely fill-out the questionnaire. Dependent measures were the total response rate and the completeness of the submitted questionnaire. Thereby, item nonresponse was analysed for open-ended and closed questions separately.
Abstract - optional In einem universitären und in einem kommerziellen Online-Panel wurden insgesamt 3 Experimente mit der Fragestellung durchgeführt, ob sich durch einen einfachen Vermerk in der Einladungs-E-Mail das Ausmaß des Item-Nonresponse vermindern lässt. Dazu wurden jeweils zwei Bedingungen miteinander verglichen. Der Einladungstext, der Gruppe 1 geschickt wurde, besagte, dass unter allen Teilnehmern XY verlost wird, wogegen der ansonsten gleichlautende E-Mail-Text, den Gruppe 2 erhielt, erwähnte, dass die Verlosung nur unter jenen Personen stattfindet, die den Fragebogen vollständig beantworten. Abhängige Variablen waren die Ausschöpfungsquote sowie die Vollständigkeit des Ausfüllens. Dabei wurde der Item-Nonresponse getrennt für offene und geschlossene Fragen ausgewertet.
