A significant challenge for current survey research is gaining participation among young adults. The aim of this study is to increase participation of young adults by implementing a mixed mode (mail/web) approach. While some research on offering mixed modes has suggested a decrease in response rates (Dillman et al., 2008; Gentry, 2008; Griffen, Fischer, &Morgan, 2001; Grigorian & Hoffer, 2008), McCabe et al. (2006) suggests that utilizing a mail/web mixed mode approach could be effective at increasing response rates among some sub-populations, such as male college students. The timing of offering an alternative mode will be tested in this study using a survey measuring attitudes and behaviors regarding alcohol use. The survey will be administered using a 3 stage mailing to a regionally stratified statewide sample of 19-25 year olds in Nebraska. The sample will be randomly divided into four groups: 1) mail option only for all 3 mailings, 2) mail option only at 1st mailing, and mail with web option offered in the 2nd and 3rd mailings, 3) mail option only at 1st and 2nd mailing, and mail with web option offered in the 3rd mailing, and 4) mail with web option offered in all 3 mailings. Response rates will be compared to determine the effects of offering an alternative mode at different stages.
