As shown in Figure 1, among the 2,892 subjects responding to the Campus Questionnaire, 1,107 met eligibility criteria, and the 500 who agreed to participate represented ∼80% of those asked. Among these, 23 (4.6%) were subsequently dropped from the protocol because: 17 agreed to do the study but did no assessments or videos; 3 did Assessment 1 but watched no videos; and 3 did Assessment and Video 1 but had no additional participation. Deleting these individuals and their matches left 454 subjects.
