Abstract: Mental health crisis refers to an urgent situation that may seriously impact an individual's mental health,caused by life events,trauma,mental health issues,or other factors. Mental crises can include suicidal crises,violent behaviors,post-traumatic stress disorder,anxiety,and depression. Mental health crisis interventions aim to provide timely support and assistance to alleviate the negative impact of the crisis on individuals. Research on strategies for early warning of adolescent mental health crises is increasingly receiving attention,as the adolescent stage is a crucial period for individual growth,and mental crises may have profound effects on their lives and futures. Therefore,governments,schools,and social organizations can collaborate to provide professional training and resource support,including mental health counseling and guidance,to help parents and educators better address adolescent mental health crises. Strategies for early warning of adolescent mental health crises need to consider identification,intervention,comprehensive approaches,and other aspects comprehensively. Future research and practices should emphasize interdisciplinary collaboration and continue to explore more personalized and accurate early warning systems to safeguard the mental health of adolescents. In addition,parents and educators should also pay attention to early warning signals and closely monitor changes in adolescent behavior and emotional fluctuations,including but not limited to changes in emotional behavior,poor social relationships,decreased interest in hobbies,and the emergence of suicidal or self-harming behaviors. This paper reviews the identification and early warning strategies for adolescent mental health crises,aiming to provide reference for future research and practice.
