“…Studies of HIV seroprevalence among individuals with SMI have found seroprevalence rates ranging from 4% to 22.9% (Cournos et al, 1991(Cournos et al, , 1994Empfield et al, 1993;Lee et al, 1992;Meyer et al, 1993a, b;Saks et al, 1992;Schwartz-Watts et al, 1995;Silberstein et al, 1994;Stewart et al, 1994;Susser et al, 1993;Volovka et al, 1991). Research relating to HIV risk behaviors among SMI individuals indicates that as many as 40% of some samples have had more than one sexual partner during the year preceding the study (Hanson et al, 1992;Kelly et al, 1992); sexual intercourse with a known injection drug user has been reported in as many as 20% to 26% of SMI individuals (Knox et al, 1994;Steiner et al, 1992). As many as 27% or more of SMI samples have reported trading sex for drugs (Kalichman et al, 1994;McKinnon et al, 1996).…”
