The burden of mental disorders globally is enormous. Depression and anxiety show an increase in incidence during adolescence. And suicide is the second leading cause of death among young people worldwide. So early recognition and identification of risk factors, including violence, neglect, abuse and so on, is crucial to preventing future mental illness. However, relevant research is limited and the research tools used in China have differed widely and have often been used directly translated from the English with no modification to take local cultural norms into consideration. The overall aim of the research is to develop robust and easily administered tools to measure the prevalence of mental health problems throughout the age range of middle and high school children (ages 12 to 19) in China based on the current researches and then to promote long-term monitoring and comparative research in the future.
