Objective:To explore the relationship between non suicide self injury and suicide risk. Methods:One year follow-up was conducted in 146 cases of NSSI that met DSM-5 recommended diagnostic criteria. The baseline and follow-up period were assessed by NSSI behavior questionnaire, childrens anxiety scale, childrens depression scale and MINI suicide module. Results:123 cases were followed upone year later, 21 cases (17.1%) had suicide risk, 102 cases (82.9%) had no suicide risk, 7 cases (5.7%) had NSSI regression. The diagnosis type of suicide risk group was more than that of no risk group, the way of NSSI was more in baseline and follow-up period, and the frequency of NSSI and depression were higher in follow-up period (P < 0.05). Logistic regression analysis showed that the type of NSSI in baseline period was the influencing factor of suicide risk in one year.Conclusions:The risk of suicide in NSSI is higher, whatever the regression is lower. The type of NSSI is the influencing factor of suicide risk.
