Perceived behavioral control, intention to get vaccinated, and usage of online information about the human papillomavirus vaccine

Objective: Human papillomavirus (HPV) and the HPV vaccine have been examined through multiple lenses over the past several years, though there is little work examining the role of perceived behavioral control (PBC) and its impact on potential recipients retrieving, understanding, and using online information with regard to the vaccine. Method: This study used survey data to examine the role of PBC as a moderator between attitudes and intention, and subjective norms (SN) and intention to get the HPV vaccine; and PBC as a moderator when seeking out Facebook, YouTube, and Twitter as information sources about HPV. Support was found for each prediction. Results: The interaction term of SN × PBC in particular had a strong influence on intention to get the vaccine. Discussion: Planned behavior variables explain intention to get the HPV vaccine, but data also suggest a need to root this research within intervention-based strategies.
