“…McGuire (1964) posited that an attitudinal resistance inoculation treatment warns the individual of a future attitudinal attack against an existing, yet vulnerable, attitude and then presents weakened counter-attitudinal arguments to build attitudinal resistance. The effectiveness of inoculative treatments in maintaining attitudes in the presence of counterattitudinal persuasive messages has been supported by laboratory experiments (e.g., Pfau et al, 2004Pfau et al, , 2006 and successfully tested in applied settings such as political campaigns Pfau & Burgoon, 1988;Pfau, Kenski, Nitz, & Sorenson, 1990), public relations (Burgoon, Pfau, & Birk, 1995;Wan & Pfau, 2004), and advertising Pfau, 1992). In addition, the theory is supported by research in adolescent health-preventative contexts, including smoking (Pfau & Van Bockern, 1994;Pfau, Van Bockern, & Kang, 1992;Szabo & Pfau, 2002) and drinking (Godbold & Pfau, 2000).…”
