Abstract Mental health services in primary and middle schools are facing multiple challenges, including dramatic increase in mental health support, low rate of mental health screening, high vigilance against psychological therapies, and lack of initiatives among students. The interdisciplinary integration of artificial intelligence (AI) and psychology in China, combined with biosensors, language recognition, blood spectrum sensing, and counseling big data, has pointed to a novel mental health service model. This new model, incorporating human computer interaction and objective algorithm, fits the contemporary students characteristics. Through monitoring real time physiological status, regulating emotional responses, and modifying cognitive modes, AI to mental health services can work effectively in mental health screening and counseling in primary and middle schools. It may become an innovative approach to build artificial intelligence for mental health service in schools.
