“…The reasons driving resurgent risky behavior among MSM are complicated and multi-faceted, and may include a combination of psychological person-level factors (e.g., self-esteem, communication skills, self-perception of risk, self-efficacy for adopting safer sexual behaviors) (Eaton et al 2007;Elwood et al 2003;MacKellar et al 2007;Morin et al 2005;O'Leary et al 2007;Stall et al 2000;Van Kesteren et al 2007), community level factors (e.g., condom use norms, sexual identity, social support, HIV treatment optimism, prevention fatigue) (Crepaz et al 2004;Klitzman et al 2007;Kok et al 2007;Ostrow et al 2008;Stall et al 2000;Strathdee et al 1998;Sullivan et al 2007;Wolitski et al 2006), and societal variables (e.g., stigma, racism, poverty) (Bingham et al 2003;Centers for Disease Control and Prevention 2003;Easterbrook et al 1993;Harawa et al 2004;O'Leary et al 2007;Preston et al 2007). Future research might benefit from examining the role of other psychological person-level factors (e.g., identity, impulsivity, or temptation of unsafe sex), as well as contextual-level factors (e.g., geography, neighborhood composition) (Mills et al 2001), which may importantly interact with venue to determine risk (Grov et al 2007).…”
