“…The RBS has been used in other studies to measure HIV-risk sexual behavior both in terms of the frequency of unprotected sexual behaviors (Hien, Campbell, Killeen, Hu, Hansen, Jiang, et al, 2010) and the number of sexual partners (Meade, Weiss, Fitzmaurice, Poole, Subramaniam, Patkar, et al, 2010). Participants’ reported number of sexual partners was assessed to measure HIV-risk sexual behavior, consistent with previous investigations (Belenko et al, 2005; Holmes et al, 2005; Kang et al, 2002; Knittel et al, 2013; Mark et al, 2006; Meade et al, 2009; Richter, Komarek, Desmond, Celentano, Morin, Sweat, et al, 2013). Participants’ reported frequency of unprotected sexual behaviors (various unprotected penetrative and oral sexual behaviors with men and women) was also assessed, consistent with previous research (Dausey & Desai, 2003; Disney et al, 2006; McHugh et al, 2012) including a psychiatric population (Meade et al, 2008).…”
