“…Study abroad continues to be promoted by postsecondary institutions because it presumably enhances intercultural competence, self-confidence, civic dispositions, and other skills or knowledge that translate into higher educational attainment and greater success in the labor market. Prior research has indeed documented these differences between students with and without study abroad experience (Dwyer, 2004a, Engle & Engle, 2004Heinzmann et al, 2013;Murphy et al, 2014;Norris & Gillespie, 2008;Orahood, Kruze, & Pearson, 2004;Orahood, Woolf, & Kruze, 2008;O'Rear, Sutton, & Rubin, 2012;Paige et al, 2004;Paige et al, 2009;Rexeisen et al, 2008;Van Hoof & Verbeeten, 2005). However, these studies are limited by research designs that do not sufficiently account for selection bias, casting doubt on claims that study abroad experiences directly cause these changes in students Thus, it is unclear whether differences between students with and without study abroad experience are attributable to the study abroad experience itself or another unobserved difference between them.…”
