Abstract：Objective To analyze the current status of non-suicidal self-injury(NSSI)and its influencing factors in adolescents with depression,and to explore its correlation with cognitive emotion regulation and social support.Methods A total of 100 adolescent patients with depression who were admitted from March 2021 to February 2023 were enrolled.Accord-ing to the presence or absence of NSSI,they were divided into NSSI group(n=39)and non-NSSI group(n=61).The gen-eral information questionnaire,NSSI rating Questionnaire,Cognitive Emotion Regulation Questionnaire Chinese version(CERQ-C)and social support rating scale(SSRS)were used to investigate the patients.The differences in general informa-tion,CERQ-C score and SSRS score between NSSI group and non-NSSI group were compared.Multivariate logistic regression was used to analyze the related factors affecting the occurrence of NSSI.Results Among the 100 adolescent patients with de-pression,39.00%(39/100)had NSSI.There were significant differences in the degree of depression and anxiety between NSSI group and non-NSSI group(P＜0.05).Compared with the non-NSSI group,the NSSI group had significantly higher scores of rumination,catastrophizing,blaming others,and self-blame and significantly lower scores of acceptance,rational analysis,positive reappraisal,positive refocusing,and refocusing on the plan(P＜0.05,P＜0.01).The NSSI group had significantly lower support utilization score and total SSRS score than the non-NSSI group(P＜0.05).The results of multiva-riate logistic regression analysis showed that the degree of depression,rumination,catastrophizing,blaming others,and self-blame were risk factors for NSSI,and the utilization of support,positive reappraisal,positive refocusing,and refocusing on plans were protective factors for NSSI(P＜0.05,P＜0.01).Conclusion Adolescent patients with depression have a cer-tain risk of NSSI,and the occurrence of NSSI is closely related to cognitive emotion regulation and social support.
