OBJECTIVE: We sought to examine highly sexually active gay and bisexual men's
accuracy in predicting their sexual behavior for the purposes of informing future
research on intermittent event-driven HIV Pre-Exposure Prophylaxis. DESIGN: For
30 days, 92 HIV-negative men completed a daily survey about their sexual behavior
(n = 1688 days of data) and indicated their likelihood of having anal sex with a
casual male partner next day. METHOD: We used multilevel modeling to analyze the
association between self-reported likelihood of and subsequent engagement in anal
sex. RESULTS: We found a linear association between men's reported likelihood of
anal sex with casual partners and the actual probability of engaging in sex,
although men overestimated the likelihood of sex. Overall, we found that men were
better at predicting when they would not have sex than when they would,
particularly if any likelihood value greater than 0% was treated as indicative
that sex might occur. We found no evidence that men's accuracy of prediction was
affected by whether it was a weekend or whether they were using substances,
although both did increase the probability of sex. DISCUSSION: These results
suggested that, men taking event-driven intermittent Pre-Exposure Prophylaxis,
14% of doses could have been safely skipped with a minimal rate of false
negatives using guidelines of taking a dose unless there was no chance (ie, 0%
likelihood) of sex on next day. This would result in savings of over US $1300 per
year in medication costs per participant.
