The HIV Risk Assessment of Sexual Partnerships (H-RASP) was developed in order to create a retrospective measure of sexual risk-taking that can account for the differing contexts of sexual partnership(s) within a specified period of time. In order to validate the H-RASP relative to other methods of measuring sexual risk-taking, measurements from the H-RASP were compared to data from a prospective diary study of 95 young men who have sex with men over the same two-month period. We found that the H-RASP was not significantly different at measuring participants’ total number of sexual partners and total number of anal sex partners in comparison with the diaries. The two measures were significantly different in measurement of total number of condomless anal sex (CAS) partners and number of CAS acts within partnerships, such that participants on average estimated more CAS partners and acts in the H-RASP. The two measures shared 40.8% of variance on measurement of CAS partners and 44.6% of variance on CAS acts within partnerships. These results suggest that even though the H-RASP is not a perfect replication of prospective diary data, it captures a moderate proportion of the same variance, and, in the case of CAS acts within partnerships, a proportion of the variance that likely would not be measured by retrospective measures that do not ask about behaviors specific to partnerships.
