With the growing reliance on tablets and smartphones for internet access, understanding the effects of completion device on online survey responses becomes increasing important. This study uses data from the Strategic National Arts Alumni Project, a multi-institution online alumni survey designed to obtain knowledge of arts education, to explore the effects of what type of device (PC, Mac, tablet, or smartphone) a respondent uses has on his/her responses. Differences by device type in the characteristics of survey respondents, survey completion, time spent responding, willingness to answer complex and open-ended questions, and lengths of open-ended responses are discussed.
