The Hong Kong youth epidemiological study of mental health (HK‐YES)—A population‐based psychiatric epidemiology study of youth mental health in Hong Kong: A study protocol

Abstract Aim Young people in Hong Kong have been facing numerous population‐level events over the past year, including social unrest and the COVID‐19 pandemic. Representative data concerning the mental health of youths, however, is limited. The Hong Kong Youth Epidemiological Study of Mental Health (HK‐YES) is commissioned to provide the first representative prevalence estimates and correlates of mental disorders among young people in Hong Kong. It will also examine the help‐seeking behaviours, treatment rates, quality of life, and functional outcomes of the young people. More importantly, the direct and indirect economic costs of mental disorders in youths will be estimated. Methods A total of 4500 community‐dwelling participants aged 15–24 years from Hong Kong will be surveyed. Participants will be selected using a multistage stratified sampling design to provide representative estimates of the youth population in Hong Kong. All interviews will be conducted using computer‐assisted personal interviewing methods for assessments covering areas of psychiatric diagnoses, symptomatology, functioning, quality of life, disability, service utilization, health economic costs of mental disorders, and sociodemographic and lifestyle characteristics. A population‐weighted prevalence will be estimated using survey weights. Methods such as multivariate logistic and linear regression analyses will be used to calculate the risks and odds of factors that might be associated with different mental disorders. Conclusion As the first population‐based youth study in Hong Kong, HK‐YES collects extensive and representative data on different mental conditions and their associated factors among young people. The information gathered will be important for future planning on youth mental health services in Hong Kong and will offer the opportunity for a more meaningful comparison of data with other youth populations.
