Research on the effect of attentional bias on Non-suicidal Self-injury

Abstract

Non-suicidal Self-injury means that an individual intentionally and repeatedly changes or injures his or her body tissues without a clear intention to commit suicide. It is a non-lethal or less lethal destructive behavior aimed at self-injury. Self-injury is a major hidden danger to public mental health. Based on the recent research results of NSSI, this paper summarizes the relationship between NSSI and attention bias and emotion regulation. On this basis, an attempt is made to construct a model of how attention bias affects patients' NSSI by influencing their emotional information and putting forward research prospects. People are biased in processing and responding to negative emotional content, and this attention bias will increase the difficulty of emotional regulation in NSSI patients. Patients with NSSI usually have more difficulty controlling negative emotions. For NSSI patients, NSSI behavior is a common way to regulate emotions. NSSI can temporarily relieve negative emotions, and this result strengthens the association between negative emotions and NSSI. Future studies may pay more attention to brain abnormalities in NSSI patients.
