Adolescent mental disorder is a global health concern, while depression is the most prevalent type of adolescent mental disorder. The government has been very responsive in the matter, asking the education system to implement regular and universal mental health checkups for the students. Such an encouraging policy paves the way to early detection, prevention, and treatment. It, however, also faces some challenges, such as the chance of having false positives and the need for stakeholders to distinguish between screening and diagnosis. Other issues include the ethical need to follow up those screened positive and avoidance of labelling those screened positive. The universal screening at schools is hence a large-scale program that needs inter-disciplinary integrations among researchers and practitioners in psychology, psychiatry, public health, and education. The presentation offers some perspectives from the angle of public health. One of the discussions is about the nature of the screening tool. Screening tools detecting mental distress developed by psychologists and psychiatrists often focus on symptoms. The screening results may hence point directly to mental disorders. For instance, currently, PHQ-9 is a well validated tool commonly used in the universal screening of depression in the school setting. This presentation discusses about the development of a screening tool basing on protective and risk factors instead of symptoms, which may have very similar positive and negative findings comparing to PHQ-9 (ROC area of about .92). It is however, may hence involve less labelling effect and ethical issues. It may also be able to detect other mental health problems. The implications will be discussed.
