ABSTRACT

Video can be a very powerful tool for risk communication, especially for decisions that are socially complex, require considerable motivation, or entail processes that are hard to envision (Bransford et al., 1990; Kamin et al., 2003; Mitra et al., 2010; Wetzel et al., 1994). In comparison with text communication, video tends to exacerbate perceptions of risk (Garg et al, 2012; Xie et al., 2011), especially through emotional reactions (Visschers et al., 2008; Xie et al., 2011). Video has been shown to change medical testing behaviors (Frosch et al., 2001), and the inclusion of dramatized characters suffering from risky outcomes can promote behavior change over and above delivery of information alone (Davis et al., 1998).
