“…In the MGB, attitude, "a psychological tendency that is expressed by evaluating a particular entity with some degree of favor or disfavor" (Eagly and Chaiken, 1993, p. 1), indirectly affects intention through desire, while subjective norm, which refers to an individual's perceived social pressure to conduct or not conduct a certain behavior (Ajzen, 1991), has a direct impact on desire and an indirect impact on intention through desire. Perceived behavioral control, which indicates a person's understanding of the ease or difficulty of carrying out a particular behavior (Ajzen, 1991), directly affects desire and indirectly induces intention (Bagozzi and Dholakia, 2006;Perugini and Bagozzi, 2001;Poels and Dewitte, 2008;Prestwich et al, 2008;Taylor et al, 2009). That is, the roles of the variables adopted from the theory of planned behavior were redefined in the MGB, increasing its predictive power.…”
