| Objective To investigate epidemiological characteristics and influencing factors of non-suicidal self-injury （NSSI） behaviors among middle school students in Jiangmen.Methods A 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.Results A 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.Conclusion The 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. |
