title: Hostility, physical aggression and trait anger as predictors for suicidal behavior in Chinese adolescents: a school-based study.
abstract: OBJECTIVE
  This study explored the extent to which trait aggression is associated with suicidal behavior in a nationwide school-based sample of adolescents.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  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.
