Method
An online survey, conducted in spring 2007, was administered to 119 college undergraduates
at a large university in the Midwestern United States. A convenience sample
was justified because this is a novel research field for which data are difficult to obtain
and because online surveys rely on self-selection mechanisms and make randomized
sampling difficult (Riffe, Lacy, & Fico, 1998). Additionally, eight participants
(two male, six female) from the online survey respondent pool were selected for
open-ended in-depth face-to-face interviews, which were conducted June 2007.
