| Background Non-suicidal self-injury （NSSI） behaviors have become a serious global public health issue.The detection rate of NSSI behaviors among college students in China ranges from 9.8% to 13.53%. Integrated theoretical models suggest that distal family risk factors influence NSSI behaviors through emotional regulation mechanisms. However， existing researches have predominantly focused on single family risks， leaving the relationship between cumulative family risks and NSSI behaviors， as well as the underlying pathways， remain unclear.Objective To explore the effects of cumulative family risk on NSSI behaviors among college students， analyze the chain mediating roles of emotional regulation difficulties and depression， and examine the moderating effect of gender， so as to provide references for targeted interventions for NSSI behaviors in college students.Methods On March 1， 2024， a cluster sampling method was employed to select 518 college students from two universities in Heilongjiang Province. Assessments were conducted using Chinese version of the Childhood Trauma Questionnaire （CTQ）， the Difficulties in Emotion Regulation Scale （DERS）， the Patient Health Questionnaire Depression Scale-9 item （PHQ-9） and the Adolescent Self-Injury Questionnaire. Logistic regression analysis was used to examine the impact of cumulative family risk factors on NSSI behaviors among college students. Model 6 in Process 4.1 was applied to test the chain mediating roles of emotional regulation difficulties and depression in the relationship between cumulative family risk and NSSI behaviors， while model 83 was utilized to analyze the moderating effects of gender on the path "cumulative family risk → emotion regulation difficulties".Results A total of 475 （91.70%） college students completed valid questionnaires. Logistic regression analysis revealed that childhood abuse （OR=2.561， 95% CI： 1.566-2.561）， non-parental family structure （OR=2.108， 95% CI：1.102-4.029） and left-behind experience （OR=2.356， 95% CI： 1.021-5.439） were risk factors for NSSI behaviors among college students. Cumulative family risk positively predicted NSSI behaviors （β=0.345，95% CI：1.059-4.286， P<0.01）， and this relationship was mediated by a chain pathway involving emotional regulation difficulties （β=0.136，95% CI： 0.882-4.681， P<0.05） and depression （β=0.160， 95% CI： 0.316-1.073， P<0.01）. Gender moderated the relationship between cumulative family risk and emotional regulation difficulties （β=0.103， 95% CI： 1.567-8.316， P<0.01）， with cumulative family risk significantly predicting emotional regulation difficulties in female students （β=0.374， 95% CI： 0.099-0.084， P<0.01）.Conclusion Cumulative family risk can directly influence college students' NSSI behaviors， and may also indirectly affect NSSI behaviors through the mediating roles of emotional regulation difficulties and depression. The path "cumulative family risk → emotional regulation difficulties" in this mediating model is moderated by gender.［Funded by Heilongjiang Philosophy and Social Sciences Research Planning Project （number， 24SHB007）］ |
