Introduction
My research interest is about using psychological principals and behavioral science to understand people's medical decision-making processes and design tailored intervention for improving their decision making. I am specifically interested in vaccine hesitancy, antibiotic use, and climate change.

Background Seasonal influenza vaccine (SIV) greatly reduces disease burden among school-aged children, yet parental vaccine hesitancy remains a persistent challenge. Two types of SIV are available for children in Hong Kong and other locations: inactivated influenza vaccine (IIV), administered through intramuscular injection, and live attenuated inf...
Article
Background Vaccine hesitancy is complex and multifaced. People may accept or reject a vaccine due to multiple and interconnected reasons, with some reasons being more salient in influencing vaccine acceptance or resistance and hence the most important intervention targets for addressing vaccine hesitancy. Objective This study was aimed at assessin...
Article
Young adults in a transitional period may experience more stress and, hence, suffer from an increased risk of unhealthy eating. Executive function (EF) involves not only inhibitory control and mental flexibility (the ‘cool’ facet) to facilitate resistance to immediate temptations, but also affective decision making (the ‘hot’ facet) that helps to r...

The existing research on the associations between climate change-related events and mental well-being outcomes warrants several gaps. These studies either used a mono approach such as cross-sectional surveys or focused on clinical mental health outcomes. Moreover, the underlying mechanism channelling changing climate and real-time emotional well-be...

Seasonal influenza vaccine (SIV) significantly reduces influenza-related illnesses among school-aged children, yet parental vaccine hesitancy remains a persistent challenge. Two types of SIV are available for children in Hong Kong and other locations: inactivated influenza vaccine (IIV), administered through intramuscular injection, and live attenu...

The global rollout of COVID-19 vaccines faces a significant barrier in the form of vaccine hesitancy. This study adopts a dynamic and network perspective to explore the determinants of COVID-19 vaccine uptake in Hong Kong, focusing on multi-level determinants and their interconnections. Following the framework proposed by the Strategic Advisory Gro...

Promoting high vaccine uptake is a primary public health policy in mitigating the profound impact of COVID-19 pandemic. The evolution of the COVID-19 pandemic requires a dynamic evaluation of factors that are associated with COVID-19 vaccination uptake to inform a strategic plan on vaccination programmes. Using real-time population-based data that...
Article
Background: High COVID-19 vaccination uptake rates across all age groups are important for achieving herd immunity. However, age disparity in vaccination acceptance was consistently identified. Objective: Taking cues from tenets of socioemotional selectivity theory, this study examined how the contextual and psychosocial factors contributed to a...

This study aimed to gain insight from mothers who were successful in breastfeeding maintenance to develop interventions for promoting breastfeeding maintenance. Following the phenomenological framework, this qualitative study recruited mothers who had maintained breastfeeding for at least 4 months for in-depth interviews. A total of 30 in-depth int...
Article
Socially disadvantaged individuals and communities consistently showed lower COVID-19 vaccination acceptance. We aimed to examine the psychological mechanisms that could explain such vaccination disparities. This study used data from serial population-based surveys conducted since the COVID-19 vaccination programme being launched in Hong Kong (N =...
Article
Background: School-located influenza vaccination programme (SIVP) can effectively promote childhood seasonal influenza vaccination (SIV). However, the longitudinal effects of continuation and discontinuation of the SIVP on parents' vaccine hesitancy remained unknown. Methods: A two-wave longitudinal study recruited adult parents who had at least...
Article

Background: We aimed to conduct a narrative synthesis of components and indicators of community vulnerability to a pandemic and discuss their interrelationships from an ecological perspective. Methods: We searched from PubMed, Embase, Web of Science, PsycINFO, and Scopus (updated to November 2021) for studies focusing on community vulnerability...
Article
OBJECTIVES Older adults have been disproportionately affected by the COVID-19 pandemic. While COVID-19 vaccines are effective for reducing mortality and severe complications, vaccine hesitancy remains a substantial concern particularly among older adults. This was a qualitative study to explore how Chinese older adults reached a decision to delay o...

Article
Vaccine hesitancy can be heightened due to increasing negative reports about vaccines. Emphasizing the social benefits of vaccination may shift individual attention from individual to social benefit of vaccination and hence promote prosocial vaccination. In six rounds of a population-based survey conducted over one major community epidemic of coron...

We constructed a coronavirus disease community vulnerability index using micro district-level socioeconomic and demographic data and analyzed its correlations with case counts across the 3 pandemic waves in Hong Kong, China. We found that districts with greater vulnerability reported more cases in the third wave when widespread community outbreaks...
