An interventional study of Scientific videos and Vaccine chatbot in HPV Vaccination Rates, HPV Vaccine Awareness and HPV Vaccination Intention, sponsored by Xiamen University. Not yet recruiting. Open to participants aged 15 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-03-31.
Sponsored by Xiamen University · Not applicable, Interventional, and Health services research
This is an interventional study targeting female university students. The primary objective of the study is to evaluate the effectiveness of a vaccine chatbot in improving HPV vaccination rates. The secondary objectives are to evaluate the effectiveness in improving vaccine awareness and vaccination intention. All participants will be enrolled and randomly assigned to four groups: (1) vaccine chatbot plus scientific videos, (2) vaccine chatbot only, (3) scientific videos only, and (4) a control group (no intervention). The chatbot will provide immediate, validated answers to participants' HPV vaccine-related questions. The scientific videos will cover content related to HPV vaccine safety, efficacy, and other relevant information. The study will compare changes in HPV vaccine awareness, vaccination intention, and vaccination behavior between the intervention groups and the control group after the intervention to evaluate whether the three intervention strategies enhance HPV vaccine awareness, vaccination intention, and vaccination uptake.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely.

HPV vaccination rates for female university students in all groups before and after the intervention
Whether female university students get vaccinated against HPV or have an appointment for vaccination, measured by self-report and validated by vaccination information system
Time frame: Baseline and two months
HPV vaccine awareness for eligible female university students in all groups before and after the intervention
A questionnaire consisting of 11 questions related to HPV vaccines will be used to investigate the awareness of HPV vaccines.Total knowledge score is calculated based on the number of questions answered correctly by the participants and the higher scores mean a better outcome.
Time frame: Baseline and two weeks
HPV vaccination intention for eligible female university students in all groups before and after the intervention
Female university students' willingness to vaccinate themselves, measured using a five-point Likert scale from "not willing at all" to "strongly willing"
Time frame: Baseline and two weeks
Vaccine chatbot acceptability and implementability
A questionnaire consisting of 10 questions assessing usability and feasibility, fairness and safety, user experience, and overall assessment of the chatbot, measured using a five-point Likert scale from "not willing at all" to "strongly willing"
Time frame: Two weeks
Factors influencing vaccination intention for eligible female university students
Survey items: age, education level, marital status, occupation, annual income, and awareness of vaccines.
Time frame: Two weeks and six months
HPV vaccination rates for female university students in all groups after the intervention
Whether female university students get vaccinated against HPV or have an appointment for vaccination, measured by self-report and validated by vaccination information system
Time frame: two weeks, one month and six months
