Caro, Francis G.; Ho, Teck H.; McFadden, Daniel L.; Gottlieb, Alison S.; Yee, Christine; Chan, Taizan; Winter, Joachim (2012): Using the internet to administer more realistic vignette experiments. In: Social Science Computer Review, Vol. 30, No. 2: pp. 184-201




This article illustrates an innovative method of administering stated choice studies (or vignette experiments) using computers and the Internet. The use of video clips to deliver information to research participants makes vignettes more realistic, helps to engage interest of research participants, and can reduce framing effects. The method also provides research participants with interactive options before making judgments. A study to determine the views of older people regarding residential options is used to illustrate the method. Even older people with limited experience in using computers participated successfully. The study findings showed that research participants responded both to the audiovisual characteristics of vignette persons and to the variables in the vignette structure.
