“…Among self-identifying and non-self-identifying gay men, constructs of the health belief model have been used to understand and explain sexual risk behavior (Aspinwall, Kemeny, Taylor, Schneider, & Dudley, 1991;Dawson, Fitzpatrick, Boulton, McLean, & Hart, 1992;Simon, Morse, Balson, Osofsky, & Gaumer, 1993;Wulfert, Wan, & Backus, 1996), HIV testing behavior (Maguen, Povinelli, Remafedi, & Tao, 1996), HIV treatment initiation (DiFranceisco et al, 1998), and risk-reduction intervention participation and completion (Gold & Ridge, 2001). When applied to HBV vaccination behavior, the health belief model postulates that in order for individuals to participate in HBV vaccination, they must believe: (a) getting vaccinated is not discouraged by insurmountable barriers (perceived barriers); (b) getting vaccinated against HBV would be beneficial (perceived benefits); (c) contracting HBV would have a negative impact on their lives (perceived severity); and (d) they are personally susceptible to HBV infection (perceived susceptibility).…”
