Non-suicidal self-injury (NSSI) has become an important public health issue of global concern, often occurring in adolescents, and depressive mood is closely related to NSSI. In addition, NSSI is considered a symptom of borderline personality disorder. It has been found that adolescents in secondary vocational schools are more vulnerable to behavior and emotional disorders than those in general high schools. This study investigated the risk factors associated with NSSI affecting secondary vocational school students and analyzed the role of borderline personality disorder tendencies in promoting the occurrence of NSSI among students with depressive moods.
A total of 1,848 Chinese secondary vocational students completed a self-report questionnaire. The homemade NSSI behavior questionnaire, Patient Health Questionnaire-9 and Personality Diagnostic Questionnaire-4 were used in this survey. Binary logistic regression and PROCESS software analysis were used to explore the influencing factors associated with NSSI and to test for moderating effects.
Female (OR = 3.412, 95% CI 2.301-5.060), drinking history (OR = 2.007, 95% CI 1.383-2.911), history of suicidal death exposure (OR = 3.161, 95% CI 1.999-4.999), depressive mood (OR = 2.436, 95% CI 1.668-3.558) and borderline personality disorder tendencies (OR = 2.558, 95% CI = 1.764-3.711) were independent risk factors for NSSI. Borderline personality disorder tendencies (B = 0.047, = 0.000) moderated the relationship between depressive mood and NSSI. The stronger the borderline personality tendencies, the more NSSI behavior occurred when they were depressive.
Borderline personality disorder tendencies in secondary vocational school adolescents significantly enhance the association of depressive mood with NSSI. There is a moderating role for borderline personality disorder tendencies in depressive mood and NSSI.
非自杀性自伤（NSSI）已成为全球关注的重要公共卫生问题，常发生于青少年群体，且抑郁情绪与NSSI密切相关。此外，NSSI被认为是边缘性人格障碍的一种症状。研究发现，中等职业学校的青少年比普通高中的青少年更容易出现行为和情绪障碍。本研究调查了影响中等职业学校学生NSSI的相关危险因素，并分析了边缘性人格障碍倾向在促进抑郁情绪学生发生NSSI中的作用。
共有1848名中国中等职业学校学生完成了一份自陈式问卷。本调查使用了自制的NSSI行为问卷、患者健康问卷-9和人格诊断问卷-4。采用二元逻辑回归和PROCESS软件分析来探索与NSSI相关的影响因素，并检验调节效应。
女性（OR = 3.412，95%CI 2.301 - 5.060）、饮酒史（OR = 2.007，95%CI 1.383 - 2.911）、有自杀死亡事件接触史（OR = 3.161，95%CI 1.999 - 4.999）、抑郁情绪（OR = 2.436，95%CI 1.668 - 3.558）和边缘性人格障碍倾向（OR = 2.558，95%CI = 1.764 - 3.711）是NSSI的独立危险因素。边缘性人格障碍倾向（B = 0.047， = 0.000）调节了抑郁情绪与NSSI之间的关系。边缘性人格倾向越强，抑郁时发生的NSSI行为就越多。
中等职业学校青少年的边缘性人格障碍倾向显著增强了抑郁情绪与NSSI之间的关联。边缘性人格障碍倾向在抑郁情绪与NSSI之间起调节作用。
