Acceptability, Usability and Preliminary Effectiveness of ChatGPT in Increasing Seasonal Influenza Vaccination Uptake Among Older Adults in Hong Kong

In this project, we will train a ChatGPT to provide real-time answers to questions related to the SIV for older adults in Hong Kong.

This study aims to evaluate the usability, acceptability, and preliminary effectiveness of the ChatGPT among 50 community-living people aged 65 years and above in Hong Kong.

The primary objectives are to evaluate the usability and acceptability (including the extent of usage and subjective experiences of behavioural, cognitive, and affective engagement) of the ChatGPT at the end of the 4-week intervention period (T1).

The secondary objectives are to evaluate the following conditions measured at T1, as compared to those measured at baseline (T0):

1. Self-reported uptake of SIV in the past month. 2. Changes in behavioural intention to receive SIV for the approaching flu season. 3. Changes in knowledge and attitudes related to SIV.
