- Brief Summary
Vaccine hesitancy is defined as 'delay in acceptance or refusal of vaccines, despite the availability of vaccine service' and was named one of the top ten global health threats by the World Health Organization in 2019.
Our proposed study will aim to develop and evaluate the effectiveness of a Web-based psychoeducation programme to address Covid-19 vaccine hesitancy, 'AI-driven Vaccine Communicator' (including educational materials, animations of vaccine research and development, and an MI communication skills-based AI, digital assistant).
Our goal is to standardise our intervention so that it can serve as an effective toolkit for clinicians/healthcare providers to increase Hong Kong residents' motivation to vaccinate and to ensure that the programme can be adapted to viral mutations and newly developed vaccines in the medium/long term.
- Detailed Description
This study is a two-arm, single-blind pilot randomized controlled trial, and it will be adopted to evaluate the efficacy of the 'AI-driven Vaccine Communicator' relative to being self-informed about Covid-19 vaccines.
Also, to address the widespread hesitancy among Hong Kong residents toward Covid-19 vaccines, we will develop a Web-based psychoeducation programme, 'AI-driven Vaccine Communicator,' driven by artificial intelligence (AI) techniques based on the Vaccine Hesitancy Determinants Matrix Model and MI communication skills and concepts (theoretical underpinnings). After developing and piloting this programme, we will test its effectiveness among members of the population who are hesitant about Covid-19 vaccines. The programme will then be refined further and standardised to use the most relevant information and effective communication skills to promote acceptance of Covid-19 vaccines among a wider Hong Kong population. Clinicians and healthcare providers will be able to utilise our programme as a toolkit in their usual practice when working with clients who are hesitant about Covid-19 vaccines.

Group Intervention Description AI-driven vaccine communicator intervention group AI-driven Vaccine Communicator The intervention will include five modules web-based psychoeducation programme (two modules sessions weekly, each module lasts for 15-20 minutes) which includes educational materials, animations of vaccine research and development, and an MI communication skills-based AI, digital assistant. Self-learning of COVID-19 vaccine knowledge control group Self-learning of COVID-19 vaccine knowledge Participants in the control group will be given HK government websites in COVID-19 vaccine and invite to join the online examination in relation to Covid-19 vaccine knowledge.
- Primary Outcome Measures
Name Time Method Vaccine hesitancy at pre-test Vaccine hesitancy will be assessed at pre-intervention. Vaccine hesitancy measured by Adult Vaccine Hesitancy scale and a single question 'plan for next dose'
Vaccine hesitancy at six months follow-up Vaccine hesitancy will be assessed after six months follow-up. Vaccine hesitancy measured by Adult Vaccine Hesitancy scale and a single question 'plan for next dose'
Vaccine hesitancy at post-intervention Vaccine hesitancy will be assessed five weeks post the commencement of the intervention (at post-intervention). Vaccine hesitancy measured by Adult Vaccine Hesitancy scale and a single question 'plan for next dose'
Vaccine hesitancy at three months follow-up Vaccine hesitancy will be assessed after three months follow-up. Vaccine hesitancy measured by Adult Vaccine Hesitancy scale and a single question 'plan for next dose'
- Secondary Outcome Measures
Name Time Method Vaccine confidence at pre-test Vaccine confidence will be assessed at pre-intervention. Vaccine confidence assessed by Vaccine Confidence Index scale
Vaccine confidence at post-intervention Vaccine confidence will be assessed five weeks post the commencement of the intervention (at post-intervention). Vaccine confidence assessed by Vaccine Confidence Index scale
Vaccine confidence at three months follow-up Vaccine confidence will be assessed after three months follow-up. Vaccine confidence assessed by Vaccine Confidence Index scale
Vaccine confidence at six months follow-up Vaccine confidence will be assessed after six months follow-up. Vaccine confidence assessed by Vaccine Confidence Index scale
Vaccine readiness at pre-test Vaccine readiness will be assessed at pre-intervention. Participants' perception of their degree of attitudinal change using three one-item measures of readiness for vaccine perception: How important is it for you to receive a COVID-19 vaccine?; How ready are you to receive a COVID-19 vaccine?; How confident are you about receiving a COVID-19 vaccine?
Vaccine readiness at post-intervention Vaccine readiness will be assessed five weeks post the commencement of the intervention (at post-intervention). Participants' perception of their degree of attitudinal change using three one-item measures of readiness for vaccine perception: How important is it for you to receive a COVID-19 vaccine?; How ready are you to receive a COVID-19 vaccine?; How confident are you about receiving a COVID-19 vaccine?
Vaccine readiness at three months follow up Vaccine readiness will be assessed after three months follow-up. Participants' perception of their degree of attitudinal change using three one-item measures of readiness for vaccine perception: How important is it for you to receive a COVID-19 vaccine?; How ready are you to receive a COVID-19 vaccine?; How confident are you about receiving a COVID-19 vaccine?
Vaccine readiness at six months follow up Vaccine readiness will be assessed after six months follow-up. Participants' perception of their degree of attitudinal change using three one-item measures of readiness for vaccine perception: How important is it for you to receive a COVID-19 vaccine?; How ready are you to receive a COVID-19 vaccine?; How confident are you about receiving a COVID-19 vaccine?
Vaccine-Related Health Literacy at pre-test Vaccine-Related Health Literacy will be assessed at pre-intervention. Vaccine-Related Health Literacy assessed by Chinese version of the European Health Literacy Survey Questionnaire
Vaccine-Related Health Literacy at post-intervention Vaccine-Related Health Literacy will be assessed five weeks post the commencement of the intervention (at post-intervention). Vaccine-Related Health Literacy assessed by Chinese version of the European Health Literacy Survey Questionnaire
Vaccine-Related Health Literacy at three months follow up Vaccine-Related Health Literacy will be assessed after three months follow-up. Vaccine-Related Health Literacy assessed by Chinese version of the European Health Literacy Survey Questionnaire
Vaccine-Related Health Literacy at six months follow up Vaccine-Related Health Literacy will be assessed after six months follow-up. Vaccine-Related Health Literacy assessed by Chinese version of the European Health Literacy Survey Questionnaire
Trust in government at pre-test Trust in government will be assessed at pre-intervention. Trust in government will be measured with the four-item Vaccine Confidence Index.
Trust in government at post-test Trust in government will be assessed five weeks post the commencement of the intervention (at post-intervention). Trust in government will be measured with the four-item Vaccine Confidence Index.
