title: Psychotic-like experiences are associated with suicidal feelings and deliberate self-harm behaviors in adolescents aged 12-15 years.
abstract: OBJECTIVE
  Psychotic disorders are a significant risk factor for suicide, especially among young people. Psychotic-like experiences (PLEs) in the general population may share an etiological background with psychotic disorders. Therefore, the present study examined the association between PLEs and risk of suicide in a community sample of adolescents.
  
  
  METHODS
  Psychotic-like experiences, suicidal feelings, and self-harm behaviors were studied using a self-report questionnaire administered to 5073 Japanese adolescents. Depression and anxiety were evaluated using the 12-item General Health Questionnaire (GHQ).
  
  
  RESULTS
  The presence of PLEs was significantly associated with suicidal feelings (OR = 3.1, 95% CI = 2.2-4.5) and deliberate self-harm behaviors (OR = 3.1, 95% CI = 2.0-4.8) after controlling for the effects of age, gender, GHQ-12 score, victimization, and substance use. Suicidal feelings and behaviors were more prevalent in subjects with a greater number of PLEs.
  
  
  CONCLUSIONS
  Psychotic-like experiences may increase the risk of suicidal problems among adolescents.
