About this study

Official title: A Study on the Effectiveness of Large Language Model-Based Chatbot Interventions Among Parents of Junior High School Girls in Improving Human Papillomavirus (HPV) Vaccine Awareness, Intention and Vaccination Rates

This is an interventional study targeting parents of junior high school girls. The primary objective of the study is to evaluate the effectiveness of a vaccine chatbot in improving HPV vaccination rates among parents' junior high school girls. The secondary objectives are to evaluate the effectiveness in improving vaccine awareness and vaccination intention among parents. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Human papillomavirus (HPV) vaccination rates for parents' junior high school girls in all groups before and after the intervention

    Whether junior high school girls get vaccinated against HPV or have an appointment for vaccination, measured by self-report and validated by vaccination information system

    Measured: Baseline and two months

Secondary outcomes (2)
  1. HPV vaccine awareness for eligible parents of junior high school girls 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.

    Measured: Baseline and two weeks

  2. HPV vaccination intention for eligible parents of junior high school girls in all groups before and after the intervention

    Parents' willingness to vaccinate their junior high school girls, measured using a five-point Likert scale from "not willing at all" to "strongly willing"

    Measured: Baseline and two weeks

Questions about this trial

What is this clinical trial studying?

A study testing Scientific videos and Vaccine chatbot in people with HPV Vaccination Rates and HPV Vaccine Awareness, run by Xiamen University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 15 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Human papillomavirus (HPV) vaccination rates for parents' junior high school girls in all groups before and after the intervention (time frame: Baseline and two months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2026.
