Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this study is to determine the effects of message framing (gain vs. loss) on African American parents' acceptance of the HPV vaccine and how such effects are moderated by parents' salient beliefs prior to message exposure. Participants are randomized into gain and loss conditions in which they view either gain-framed or loss-framed HPV vaccination messages. Key outcome variables include parents' attitudes and intentions toward vaccinating their children against HPV.
