Improvement of Parent’s Awareness, Knowledge, Perception, and Acceptability of HPV Vaccination After a Structured-educational Intervention

Abstract Background: Regardless of the disease burden of HumanPapilloma Virus (HPV), the vaccine has not been included in the Indonesia National Immunization Program. Since 2017 there was a demonstration program of the HPV vaccination in Yogyakarta Province. This vaccine was given free to female primary school students in the 5 th and 6 th grades (11-13 years old). This study aimed to assess whether a structured-educational intervention focus on HPV increases the parental awareness, knowledge, and perceptions toward HPV and the vaccine acceptability. Methods: We conducted a pre-post structured-educational intervention study from July to August 2017 before the implementation of the HPV vaccination demonstration program, in Kulon Progo District, Yogyakarta Province, Indonesia. Parents of female primary school students grades 5 th and 6 th were selected using a school-based proportional random sampling. A pediatric resident provided a structured-educational intervention, which consists of the burden and risk of HPV disease, as well as the benefit and safety of the vaccine. Parents were required to complete validated self-administered questionnaires before and after the structured-educational intervention. Results: A total of 506 parents participated. Before receiving the structured-educational intervention, parents' awareness of HPV infection and the vaccines were low. Only 49.2% of parents had heard HPV infection, and 48.8% had heard about the vaccine. After the structured-educational intervention, there were significant improvements in parent’s awareness, knowledge, and perceptions of HPV infection, cervical cancer, and HPV vaccination (all p <0.001). HPV vaccine's acceptability increased from 74.3% to 87.4% ( p <0.001). There was a significant correlation between increasing HPV vaccine acceptability with the improvement of awareness, knowledge, and perception toward HPV infection, cervical cancer and HPV vaccination (r=0.32 to 0.53, p <0.001). After the structured-educational intervention, better knowledge and positive perceptions of HPV vaccination were predictive of HPV vaccine's acceptability with OR 1.90 (95%CI:1.40-2.57) and OR 1.31(95%CI:1.05-1.63), respectively. Conclusions: A structured-educational intervention is effective in improving parental awareness, knowledge, and perceptions toward HPV as well as the acceptability of the vaccine. The structured-educational intervention designed for parents have important implications for improving vaccine acceptability.
