Note. ^aOrdinal index created by summing the number of correct responses to questions used to elicit information regarding functional knowledge of HIV prevention strategies (Cronbach’s α = 0.92). ^bResponses to this question collected as an ordinal measure with 0 representing the least amount of concern and 10 representing the greatest amount of concern. ^cIncludes 21 non-Hispanic Black/African American, 13 Asian, 8 Native American/Alaskan Native, 1 Native Hawaiian/Pacific Islander, and 22 others. ^dIncludes 89 with an Associate’s/Technical degree, 171 with some college education, 48 with a high school diploma or General Educational Development (GED), and 7 with some high school education. ^eIncludes 102 bisexual, 7 heterosexual/straight, 11 questioning/unsure, 2 queer, and 2 others. ^fDescribed to participants as “Someone you feel committed to above all others. You might call this person your boyfriend, partner, significant other, spouse, or husband.” Includes 324 in a monogamous relationship, 122 in an open relationship with restrictions, and 25 in an open relationship without restrictions. CAS = condomless anal sex; aOR = adjusted odds ratio; CI = confidence interval.
