title: Association between school bullying levels/types and mental health problems among Taiwanese adolescents.
abstract: BACKGROUND
  Few studies have compared the risks of mental health problems among the adolescents with different levels and different types of bullying involvement experiences.
  
  
  METHODS
  Bullying involvement in 6,406 adolescents was determined through use of the Chinese version of the School Bullying Experience Questionnaire. Data were collected regarding the mental health problems, including depression, suicidality, insomnia, general anxiety, social phobia, alcohol abuse, inattention, and hyperactivity/impulsivity. The association between experiences of bullying involvement and mental health problems was examined. The risk of mental health problems was compared among those with different levels/types of bullying involvement.
  
  
  RESULTS
  The results found that being a victim of any type of bullying and being a perpetrator of passive bullying were significantly associated with all kinds of mental health problems, and being a perpetrator of active bullying was significantly associated with all kinds of mental health problems except for general anxiety. Victims or perpetrators of both passive and active bullying had a greater risk of some dimensions of mental health problems than those involved in only passive or active bullying. Differences in the risk of mental health problems were also found among adolescents involved in different types of bullying.
  
  
  CONCLUSIONS
  This difference in comorbid mental health problems should be taken into consideration when assessing adolescents involved in different levels/types of bullying.
