Abstract
Nonsuicidal self-injury (NSSI), also referred to as self-injurious behavior (SIB), are different terms to describe behaviors where the demonstrable injury is self-inflicted. The behavior involves deliberate tissue damage that is usually performed without suicidal intent. The term self-mutilation is also sometimes used, although this phrase evokes connotations that some find worrisome, inaccurate, or offensive. The diagnostic study of this behavior is controversial, and it needs to be further discussed with the definition criteria of suicide and borderline personality disorder. The pathologic mechanism of nssi behavior is proposed by several theoretical models, including the functional model, developmental pathologic model, and integrative model. In the future research, the research on the psychological evaluation intervention of nssi behavior should be widened, the factors affecting nssi can be further classified, and the cross-cultural research on nssi behavior and the applicability of existing foreign research achievements in China will also become the focus of future research.
Highlights
Nonsuicidal self-injury (NSSI), referred to as self-injurious behavior (SIB), are different terms to describe behaviors where the demonstrable injury is self-inflicted
The behavior involves deliberate tissue damage that is usually performed without suicidal intent, and its related research has been paid more and more attention by researchers and clinical workers
Studies defined nssi according to some abnormal behaviors, such as cutting/scratching with a sharp tool, burning with a lighter, hitting the head against the wall, etc., and the specific injury forms may exceed more than ten kinds (Yu Feng, 2008; Sinclair, Hawton, & Gray, 2010; Ross & Heath, 2002)

The pathologic mechanism of nssi behavior is proposed by several theoretical models, including the functional model, developmental pathologic model, and integrative model. The research on the psychological evaluation intervention of nssi behavior should be widened, the factors affecting nssi can be further classified, and the cross-cultural research on nssi behavior and the applicability of existing foreign research achievements in China will become the focus of future research
