ABSTRACT

Objective@#The aim of this paper is to understand the associations between childhood abuse experience,parent-child relationship and non-suicidal self-injury (NSSI) in middle school students.@*Methods@#Stratified cluster sampling method was used to select 14 500 middle school students from Shenzhen,Zhengzhou,Nanchang and Guiyang as participants. Questionnaire survey was conducted to collect information on childhood abuse exposure,parent-child relationship and NSSI.@*Results@#The prevalence of NSSI was 14.81%,while it was higher among male students (15.95%) than female students (13.64%) (χ2=15.29,P<0.01). A multivariate Logistic regression models showed that the moderate and high level of childhood abuse (OR=2.23,3.27) and the low level of parents-child relationship (OR=1.80,1.36) were associated with high NSSI detection rate among middle school students (P<0.01). In each group of childhood abuse,low level of father-child relationship was associated with high NSSI detection rate among middle school students (OR=1.36,1.34,1.56,P<0.05). In the group with high level of childhood abuse experience,low level of mother-child relationship was associated with high NSSI detection rate (OR=1.20,P<0.05). Among male students,those with high level of childhood abuse experience,low level of parentchild relationship were associated with high NSSI detection rate (OR=1.46,1.35,P<0.01); regardless of the level of childhood abuse experience,low level of father-daughter relationship was associated with NSSI detection rate (OR=1.64,1.54,1.68,P<0.01) among females.@*Conclusion@#Childhood abuse experience and poor parent-child relationship are associated with NSSI in middle school students, with distinct gender difference. Prevention of childhood abuse and the improvement of parent-child relationship are beneficial to the prevention and control of NSSI.
