Non-suicidal self-injury（NSSI） behavior is a serious threat to the mental and physical health of adolescents， which has become an important public health problem in the world. It is particularly important to intervene actively and effectively. However， there is still a lack of effective evidence for the treatment of adolescent NSSI. In this paper， the current research status of adolescent NSSI psychotherapy， medication and physical therapy is described， to provide the basis for further exploring the treatment of adolescent non-suicidal self-injury.
