ObjectiveTo investigate epidemiological characteristics and influencing factors of non-suicidal self-injury （NSSI） behaviors among middle school students in Jiangmen.MethodsA total of 1 220 middle school students in Jiangmen were selected for the study through stratified random sampling from November to December 2020. The self-compiled general demographic questionnaire， Coping Style Scale for Middle School Students， Olweus Bully/Victim Questionnaire （BVQ）， Social Support Scale for Adolescents， and Center for Epidemiologic Studies-Depression Scale （CES-D） were used for the assessment. Then binary Logistic regression analysis was performed to screen the factors influencing NSSI behaviors in students.ResultsA total of 204 middle school students （16.72%） were found to be engaged in NSSI behaviors， of whom 67 were male and 137 were female. There were statistically significant differences between the NSSI group and the non-NSSI group in terms of gender， school period， lodging， peer relationship and academic performance （χ2=22.162， 7.247， 6.541， 45.787， 25.097， P<0.05 or 0.01）. Compared with the non-NSSI group， the NSSI group scored higher on CES-D （t=-14.240） and BVQ （t=-5.952）， lower on Social Support Scale for Adolescents （t=9.238）. Within the Coping Style Scale for Middle School Students， NSSI group had lower problem-focused coping score （t=7.148） and higher emotion-focused coping score （t=-7.038） than those of non-NSSI group. The detection rates of school bullying， verbal and relational bullying were higher in NSSI group compared with non-NSSI group （χ2=34.215， 29.785，16.465）. The differences were statistically significant （P<0.01）. Binary Logistic regression showed that depression （OR=1.090， P<0.01） and school bullying （OR=1.492， P<0.05） entered into the regression model.ConclusionThe situation of NSSI behaviors of middle school students in Jiangmen is serious， and depression and school bullying are risk factors affecting NSSI behaviors in students.
