title: [Association of loneliness, impulsivity and alcohol use with suicidal behavior in adolescents].
abstract: BACKGROUND
  Suicide and suicide attempts are public health problems. Their prevention requives the detection of predictor factors.
  
  
  OBJECTIVE
  To determine the predictive valué of loneliness, impulsivity and alcohol use on suicidal behavior in adolescents.
  
  
  METHODS
  Suicidal behavior, Loneliness (UCLA), Impulsivity (Barratt) scales and the Alcohol Use Disorders Identification Test (AUDIT), were applied to 763 high school students aged 14 to 19 years (49% males), living in Chillan, Chile.
  
  
  RESULTS
  Nineteen percent of participants had attempted suicide and 34.3% had suicidal ideation. Loneliness, impulsivity and alcohol use were directly related to suicidal behavior. These predictors explained 31 % of the suicidal behavior. The most important risk factor was loneliness, followed by femóle gender, impulsivity and alcohol use.
  
  
  CONCLUSIONS
  Loneliness, impulsivity and alcohol use are risk factors for suicide among adolescents. Women are at higher risk than men.
