Hirsch O, et al. - Adults have more diverse deficits than children with ADHD. Researchers, in this study, examined a model that explicitly distinguished positive and negative affect, problems with self-concept and emotion regulation skills as distinct but correlating factors with the symptom domains of inattention, hyperactivity, and impulsivity. As per confirmatory factory analysis, emotional dysregulation is a core symptom in adult ADHD. They identified the model to be adequate in describing the relations between and among clinically and therapeutically relevant symptoms in adult ADHD. This suggested its potential for informing future therapeutic interventions by targeting the successful and flexible use of adaptive emotion regulation skills.
