The influence of vicarious experience provided through mobile technology on self-efficacy when learning new tasks

Although subjects found the video helpful for successful performance of the task and reported high perceived similarity, subjects' level of self-efficacy regarding the task, as well as task performance did not differ significantly between the two groups. However, a secondary outcome parameter did indicate a possible difference between how subjects walked forward while wearing the scuba fins (either shuffling forward, or raising their knees high up). Future studies should investigate whether such instructional videos can contribute to higher levels of self-efficacy in mobile, technology-supported interventions in more ecologically valid settings.
