Abstract
The current HPV vaccination rate among women is still relatively low, especially among adolescent girls aged 9-14 years. Insufficient access to HPV vaccine information is one of the important reasons, but there is a lack of research on women's HPV vaccine information needs. What information do women truly need to support their decision to receive the HPV vaccine? The similarities and differences in the needs of different women are key issues worth studying. Clarifying this issue can provide a scientific reference for health education and help improve its effectiveness. Unlike traditional qualitative research, the purpose of this study is to quantify women's needs for various information related to HPV vaccines, determine the priority order of information needs through quantitative methods, and explore the similarities and differences in information needs among different women with different knowledge levels and willingness to vaccinate. This study conducted a best-worst scaling experiment to compare the preference order of 7 HPV vaccines information among parents of girls aged 9-14 years, community residents, and outpatients of cervical clinic. The results of the best-worst scaling experiment were analyzed via count-based analysis and mixed logit regression analysis. Analysis shows that information needs for the safety of HPV vaccines, how to choose HPV vaccines and the duration of HPV vaccine immunization effect are generally considered important. Parents are more concerned about the safety of vaccines, and among outpatients, how to choose vaccines is the information they most want to know. Moreover, people with higher level of knowledge are relatively more concerned about the safety of vaccines and the duration of vaccine immunity, while those who are unwilling to receive vaccines have greater informational needs for vaccine safety. Women need more information about the safety of HPV vaccines, how to choose vaccines and the duration of immune effects. The information needs for HPV vaccines vary significantly among different female populations. Developing more targeted HPV vaccine health education according to these specific needs can better meet the information needs of women and potentially improve the coverage of HPV vaccines.
