The purpose of this study was to describe college-aged females’ human papillomavirus (HPV) knowledge and beliefs, perceptions and perceived benefits of the HPV vaccine, and identify characteristics associated with vaccination status and support for HPV vaccine mandates. Data were collected from 1,105 females by an Internet-delivered questionnaire during February to March 2011. This descriptive study utilizes ² tests and t-tests to compare participant responses. HPV-related knowledge scores were 8.08 out of 11 points. Those who initiated HPV vaccination were significantly younger, single, engaged in sex, were sexually active, and had a Pap test. Participants who had more friends receiving the vaccine were significantly more likely to support mandates for 9–11 and 12–17 years and were more likely to complete the HPV vaccination cycle. Findings suggest the importance of educational programs adopted and delivered by school nurses, which aim to improve student knowledge and reduce misconceptions related to the HPV vaccine and vaccination mandates.
