The novel method used by Rose et al1 to corroborate self-reported condom use among female adolescents uncovered a significant discrepancy between reports of consistent use and positive Y-chromosome polymerase chain reaction (Yc-PCR) assays. Specifically, 34% of those reporting consistent use had a Yc-positive assay, suggesting that they used condoms inconsistently or incorrectly. Although the article forces us to revisit our efforts to promote correct and consistent condom use by adolescents, the authors miss the opportunity to acknowledge the ways in which their methodology supports the use of self-reported risk behavior data.
