“…Researchers have identified sexual behavior factors, such as engaging in a variety of unprotected sex acts and having casual partners (Berg, 2008;Elford et al, 2007;Halkitis et al, 2005;Mansergh et al, 2002;Reisner et al, 2008), as being related to barebacking. Further, health behavior factors like recreational drug use have been found to be associated with bareback sex (Berg, 2008;Elford et al, 2007;Kelly, Bimbi, Izienick, & Parsons, 2009;Reisner et al, 2008;Wilton, Halkitis, English, & Roberson, 2005). Other research has suggested that perceptions about HIV, notably cognitions about improved HIV drug treatments, has lessened MSM's worry about HIV and contributed to their decision to bareback (Elford et al, 2007;Mansergh et al, 2002).…”
