Dear Kyle, Of course it depends on what you define as 'very long' and 'small'. We have done an experiment where group 1 received a 'very long version' (about 30-45 minutes; it was basically the traditional mail survey with 19 product categories), and group 2 received a shorter version (~15 minutes; the traditional questionnaire split into 2, so 9 product categories). The results showed that short questionnaires have a higher response rate, although long questionnaires still generate a surprisingly high response. Furthermore, there were interesting interaction effects with the type of incentive (see Deutskens, E.C., J.C. de Ruyter, M.G.M. Wetzels, and P. Oosterveld (2004), "Response Rate and Response Quality of Internet-based Surveys: An Experimental Study". Marketing Letters 15 (1), 21-36 for more information) I hope this helped! Success with your study, Lisa

-----Original Message----- From: Kylie Veale [mailto:kylie@veale.com.au] Sent: zondag 13 juni 2004 7:06 To: air-l@aoir.org Subject: [Air-l] Internet Surveys: One or Many? Folks, I have a quick question (I think) for the group with regard to internet surveys. Does anyone have an opinion and/or references to literature about whether the implementation of several small surveys is better that one very long survey? When I say 'better', I mean a positive effect on survey responses? Thanks Kylie ------------------------------------------ Kylie J.
