How adolescent Japanese girls arrive at human papilloma virus vaccination: A semistructured interview study

Abstract

We examined the human papilloma virus (HPV) vaccination process in adolescent Japanese girls, including protective and obstructive factors to develop and practice enlightenment activities and educational interventions for promoting HPV vaccination to adolescent Japanese girls and their families. We conducted semistructured interviews with 20 adolescent Japanese girls who lived in the wider Tokyo area. To analyze the interview data, we adopted the modified grounded-theory approach. We identified three stages in the vaccination process: first encounter with cervical cancer and HPV vaccine, thoughts about vaccination, and adjustment with parents toward vaccination. The girls "knew" their knowledge and information on cervical cancer and the HPV vaccine from experts, parents, and friends, "considered and discussed" HPV vaccination in their own way or with parents, and "arranged" actual vaccination. This process was influenced by the promoting/obstructive factors in each stage. Healthcare providers should understand the experiences and feelings of adolescent girls who were confronted with HPV vaccination in the context of their vaccination process and conduct enlightenment activities to promote vaccination, keeping the promoting and obstructive factors suggested in this study in mind.
