Official title
A Randomized Controlled Trial Evaluating a Chatbot-delivered Theory-based Online Intervention in Increasing Seasonal Influenza Vaccination Uptake Among Children Aged 3-6 Years
Overview
This randomized controlled trial will compare the efficacy of a Chatbot-delivered stage-of-change-tailored online intervention versus a Chatbot-delivered non-stage-of-change-tailored online intervention for mothers in increasing seasonal influenza vaccination uptake of their children aged 3-6 years. Mothers of children aged 3-6 years will be randomized evenly into either the intervention or the control group. In the intervention group, the Chatbot will assess mothers' stage of change regarding their children's seasonal influenza vaccination uptake and deliver SOC-tailored interventions through WhatsApp every two weeks for four times. In the control group, the Chatbot will provide a standard and non-stage-of-change-tailored intervention every two weeks for four times. All participants will complete three telephone surveys at baseline (T0), after completion of the intervention (T1) and three months after T1 (T2).
Interventions
- Behavioral Stage-of-change-tailored intervention
The Chatbot will deliver four intervention sessions tailored to participants' current stage of change regarding their index child's seasonal influenza vaccination uptake at Week 0, 2, 4, and 6. Participants will also have access to real-time Question-and-Answer (QA) function provided by the chatbot to address their questions related to seasonal influenza vaccination during the intervention period (week 0-6), and they are free to spend as much time as they want on such function. - Behavioral Non-stage-of-change-tailored intervention
The Chatbot will automatically send participants a link to access a standard online video at week 0, 2, 4 and 6. Participants will also have access to real-time Question-and-Answer (QA) function provided by the chatbot to address their questions related to seasonal influenza vaccination during the intervention period (week 0-6), and they are free to spend as much time as they want on such function.
Primary outcome measures
- Index child's seasonal influenza vaccination uptake reported by his/her mother with validation [Time frame: 3 months after completion of the interventions (T2)]
