Background: HPV vaccines are well known to prevent several devastating HPV-associated cancers-when administered before sexual activity begins. We have previously found that mothers in Japan play an important role in a young girl's vaccination decision-making, and that educational intervention with the mothers positively changed their attitude towards the HPV vaccine. The role of fathers is still unclear. We report here similar effects can be achieved by an educational intervention with the fathers.
Method: We conducted an online survey of 1648 Japanese fathers as having 13-18 year-old daughters. In this group, 1450 fathers had HPV-unvaccinated daughters. Roughly half, 721, were supplied an educational sheet concerning cervical cancer, which included information regarding the safety and efficacy of the HPV vaccine, the other 729 did not receive the sheet. Afterwards, a self-administered questionnaire obtained information from both groups of fathers. We evaluated their attitudes and intentions to inoculate their daughters and willingness to be associated with the vaccination decision-making process.
Results: Paternal education with an information sheet was associated with an increased odds ratio for changing the father's attitude in a positive direction, but it was not associated with improving the father's intention to their have their daughters inoculated, nor the father's willingness to be associated with the decision-making process.
Conclusion: While educational intervention can promote a father's positive attitude towards HPV vaccination, it is ineffective at promoting a positive intention to follow through to inoculate their daughters or improving their willingness to assist in the decision-making process.
