Adolescent homicide rates have aroused global concern and better understanding of factors relating to homicidal ideation is critical. This study aimed to explore the correlates of homicidal ideation in a cross-sectional school-based sample of Chinese early adolescents.
The data were obtained from the cross-sectional project 'Health and Risky Behaviors among Middle School Students in Anhui Province, China', which was conducted in November 2020. The entire sample of 5724 middle school students who completed the questionnaires was included in the present study. Network analysis was employed to examine the correlates of homicidal ideation at three levels: individual (sex, academic performance, childhood trauma, aggression, anxiety, severe physical illness), family (family economic status, family violence, parental crime, parental mental illness, relationship with father, relationship with mother), and school (school-bullying victimization and perpetration, relationship with classmates, teacher support). Additionally, sensitivity analyses were performed to evaluate sex differences.
In the whole sample, 11.7 % of students reported homicidal ideation in the past six months. Network analyses revealed that individual-level (childhood maltreatment, aggression and anxiety) and school-level (teacher support, school-bullying victimization and perpetration) factors were associated with homicidal ideation. Sensitivity analyses showed that homicidal ideation was associated with academic performance and school-bullying victimization in boys but not in girls, although the sex differences were not significant.
The cross-sectional design of this study limited the inference of causality.
This study identified some correlates of homicidal ideation and provided some novel insights into homicide prevention and intervention in Chinese early adolescents.
青少年的凶杀率引起了全球关注，更好地理解与杀人意念相关的因素至关重要。本研究旨在探索中国初中生横断面上与杀人意念相关的因素。
数据来自于 2020 年 11 月进行的“中国安徽省中学生健康与危险行为”的横断面研究项目。本研究纳入了完成问卷的 5724 名中学生的全部样本。采用网络分析来检验个体（性别、学业成绩、儿童创伤、攻击性、焦虑、严重身体疾病）、家庭（家庭经济状况、家庭暴力、父母犯罪、父母精神疾病、与父亲的关系、与母亲的关系）和学校（学校欺凌受害和施害、与同学的关系、教师支持）三个层面上与杀人意念相关的因素。此外，还进行了敏感性分析以评估性别差异。
在整个样本中，11.7%的学生在过去六个月有杀人意念。网络分析显示，个体层面（儿童期虐待、攻击性和焦虑）和学校层面（教师支持、学校欺凌受害和施害）的因素与杀人意念有关。敏感性分析表明，在男生中，学业成绩和学校欺凌受害与杀人意念有关，但在女生中则没有，尽管性别差异不显著。
本研究的横断面设计限制了因果关系的推断。
本研究确定了一些与杀人意念相关的因素，并为中国青少年的凶杀预防和干预提供了一些新的见解。
