Phasic Versus Tonic Irritability: Differential Associations With Attention-Deficit/Hyperactivity Disorder Symptoms

Irritability is a multifaceted construct in pediatric psychopathology. It has been conceptualized as having a ‘phasic’ dimension and a ‘tonic’ dimension. Disruptive mood dysregulation disorder (DMDD) is defined by the presence of both dimensions. Severe irritability, or DMDD, is highly comorbid with attention-deficit/hyperactivity disorder (ADHD). However, it is unknown whether the presence of ADHD modulates the expression of phasic and tonic irritability.
