Impulsive aggression in adults with attention-deficit/hyperactivity disorder

Area of Science:

• Psychiatry
• Clinical Psychology
• Neurodevelopmental Disorders

Background:

• Attention-deficit/hyperactivity disorder (ADHD) criteria include impulsivity, which can manifest as aggression.
• Impulsive aggression is not explicitly listed in DSM-IV ADHD criteria.
• Understanding the link between ADHD and impulsive aggression is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To investigate the association between features of adult attention-deficit/hyperactivity disorder (ADHD) and impulsive aggression.
• To determine if ADHD symptoms predict impulsive aggression in adult males.
• To compare the predictive strength of ADHD features versus other factors like verbal IQ and psychopathology on impulsive aggression.

Main Methods:

• Seventy-three adult males diagnosed with DSM-IV ADHD participated.
• Informants also completed questionnaires.
• Impulsive aggression was assessed using criteria for borderline personality disorder (BPD) related to hot temper and self-harm.

Main Results:

• Features of ADHD were found to predict comorbid impulsive aggression.
• Verbal IQ demonstrated a stronger association with impulsive aggression than ADHD features.
• Comorbid psychopathology was also more strongly associated with impulsive aggression compared to ADHD features.

Conclusions:

• Findings suggest that features of impulsive aggression, such as a 'hot temper/short fuse,' should be considered within the adult ADHD syndrome.
• There is an overlap between features of impulsive aggression in ADHD and borderline personality disorder (BPD).
• These results can inform the selection of research samples for future studies on ADHD and aggression.
