title: Impulsive aggression in adults with attention-deficit/hyperactivity disorder.
abstract: OBJECTIVE
  DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD) include examples of 'impulsivity'. This term can refer to various dysfunctional behaviours, including some examples of aggressive behaviour. However, impulsive aggression is not included in the DSM-IV criteria for ADHD. The associations of impulsive aggression with ADHD were investigated.
  
  
  METHODS
  Seventy-three male adults with DSM-IV ADHD, and their informants, completed questionnaires. Impulsive aggression was assessed by ratings of two criteria for borderline personality disorder (BPD), involving hot temper and/or self-harm.
  
  
  RESULTS
  Logistic regression indicated that features of DSM-IV ADHD were predictors of comorbid impulsive aggression. However, compared with ADHD features, verbal IQ and comorbid psychopathology were more strongly associated with impulsive aggression.
  
  
  CONCLUSIONS
  The findings support the inclusion of features of impulsive aggression, such as hot temper/short fuse, in the ADHD syndrome in adults. These overlap with features of BPD. The findings inform the selection of research samples.
