This study explored the extent to which trait aggression is associated with suicidal behavior in a nationwide school-based sample of adolescents.
A nationwide sample of 14,537 high school students in urban areas of China was recruited. Information concerning suicide ideation, plans, attempts, trait aggression and other risk factors was collected by a self-reported questionnaire. Multivariate regression analyses were employed to predict suicidal behavior.
Approximately 18.5% of students reported suicide ideation, 8.7% reported suicide plans, and 4.1% reported attempts during the past one year. Hostility and trait anger had a significant positive association with suicidal ideation. Hostility and physical aggression were positively related to suicide plans. Hostility had a positive correlation with suicide attempts, while trait anger was inversely associated with suicide attempts.
This study suggests that hostility, physical aggression and trait anger may be able to be used to predict suicidal behavior among adolescents. Suicide prevention programs should target at attenuating the severity of hostility, anger and physical aggression. But teachers and parents should also give close attention to students with low trait anger.
本研究旨在探讨特质攻击性在多大程度上与青少年全国性学校样本中的自杀行为有关。
在中国城市地区招募了一个由 14537 名高中生组成的全国性样本。通过自我报告问卷收集有关自杀意念、计划、尝试、特质攻击性和其他风险因素的信息。采用多元回归分析预测自杀行为。
约 18.5%的学生报告在过去一年中有过自杀意念，8.7%报告有过自杀计划，4.1%报告有过自杀尝试。敌意和特质愤怒与自杀意念呈显著正相关。敌意和身体攻击与自杀计划呈正相关。敌意与自杀尝试呈正相关，而特质愤怒与自杀尝试呈负相关。
本研究表明，敌意、身体攻击和特质愤怒可能能够用于预测青少年的自杀行为。自杀预防计划应针对降低敌意、愤怒和身体攻击的严重程度。但教师和家长也应密切关注特质愤怒程度较低的学生。
