ExpérimentalChatbot Intervention Group
Participants in this arm will be granted access to an interactive, LLM-powered HPV vaccine chatbot for a period of three months. They are invited to use the chatbot to ask any questions related to HPV and HPV vaccine to receive personalized and accurate information. The chatbot invitation will be sent every weeks to reinforce the intervention within the first month.
LLM-Powered HPV Vaccine Chatbot
A vaccine chatbot delivered via WeChat or a web browser, designed to provide information and health education about the HPV vaccine. The chatbot is powered by large language models and is trained on an expert-validated knowledge base derived from authoritative sources such as the WHO and China CDC to ensure accuracy. The knowledge base is validated by experts. The chatbot engages users in interactive, conversational ...Afficher plus

HPV Vaccine Uptake
Whether participants get vaccinated against HPV, measured by official vaccination records.

Critère secondaire d'évaluation
Critères d'évaluationDescription de la mesurePériode
HPV Vaccine Hesitancy
HPV vaccine hesitancy will be measured using a 5-point Likert scale that assesses a participant's willingness to receive the HPV vaccine, with options ranging from "very willing" to "very unwilling". A higher score on the scale indicates higher hesitancy.
The same day after the intervention
HPV Vaccine Confidence
Vaccine Confidence Index (VCI) that assesses confidence in the importance, effectiveness, and safety of vaccines using a 5-point Likert scale (1 = strongly disagree, 5 = strongly agree). A higher score indicates greater confidence.
The same day after the intervention
HPV Vaccine Literacy
A series of questions about HPV vaccine knowledge and misinformation. Total literacy score is calculated based on the number of questions answered correctly by the participants.
