Non-suicidal self-injury (NSSI) behaviour is very common among adolescents. Its prevalence and behavioural characteristics may vary according to regional and cultural differences. Investigation of NSSI locations and diagnosis of adolescents with NSSI are relatively lacking in China.
The study objective was to determine the prevalence and features of NSSI among middle school students in Shanghai.
The participants were from grade 6 to 8 selected from three junior schools in Jing'an District. Consenting students completed the Ottawa Self-Injury Inventory to determine the prevalence and characteristics of NSSI. Those who indicated NSSI within the past month were administered the Mini-International Neuropsychiatric Interview for Children and Adolescents to assess for emotional disorders.
The result shows 510 participants (21.7%; mean age 13.51 (0.97) years old; 56.7% female) reported at least one instance of NSSI during the previous 12 months. NSSI was significantly more common in girls than boys (24.9% vs 18.5%; χ=14.03, p=0.00). Commonly reported reasons for NSSI were for internal and external emotion regulation (87.9%, 82.3%) and social influence (57.8%). Anxiety disorders were the most common (28.9%) disorder associated with NSSI.
The rate of NSSI of middle school students in Shanghai inner bound is similar to those reported in North American and European youth. It is essential that school mental health professionals are aware of how to manage NSSI within the school setting.
非自杀性自伤（NSSI）行为在青少年中非常普遍。其患病率和行为特征可能因地区和文化差异而有所不同。在中国，对NSSI发生地点的调查以及对有NSSI行为青少年的诊断相对较少。
本研究旨在确定上海中学生中NSSI的患病率及特征。
研究对象为从静安区三所初中选取的六年级至八年级学生。同意参与的学生完成渥太华自伤量表以确定NSSI的患病率及特征。过去一个月内有NSSI行为的学生接受儿童及青少年版迷你国际神经精神访谈以评估情绪障碍。
结果显示，510名参与者（21.7%；平均年龄13.51（0.97）岁；56.7%为女性）报告在过去12个月中至少有一次NSSI行为。NSSI在女孩中比男孩中更为常见（24.9%对18.5%；χ=14.03，p = 0.00）。NSSI常见的原因是内在和外在情绪调节（87.9%，82.3%）以及社会影响（57.8%）。焦虑障碍是与NSSI相关的最常见（28.9%）的障碍。
上海内环线以内中学生的NSSI发生率与北美和欧洲青少年的报告相似。学校心理健康专业人员必须了解如何在学校环境中处理NSSI问题。
