Lingnan University was commissioned to conduct a Hong Kong School Children Happiness Annual Survey in 2012. In 2017/18 this annual study was augmented by including a survey on life education in schools. Since 2023, the Lingnan team was joined by the Department of Paediatrics and Adolescent Medicine of the University of Hong Kong, the Department of Paediatrics of the Chinese University of Hong Kong, and the Hong Kong Paediatric Society. The 2024/2025 study began with an invitation sent to all Hong Kong’s subvented schools in March 2023. We enlisted a total of 10 primary schools and 8 secondary schools in this study, covering 1752 primary school students, 1982 secondary school students, and 116 teachers.
