Relationship Between ADHD-Like Traits and Emotion Dysregulation in the Adult General Population

Objectives Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder classically characterised by inattention and/or hyperactivity/impulsivity. However, emotion-related problems are also common in people with ADHD, although there is disagreement about their relationship with the classical symptoms of ADHD. Here, we investigated the relationship between emotion dysregulation and ADHD-like traits in a non-clinical group of adults. Method In a group of 1074 individuals, average age 30.27 years, 656 females, 402 males and 16 who identified as ‘other’, with 76.8% describing themselves as ‘white’, were administered the Adult ADHD Self-Report Scale (ASRS) and the Difficulties in Emotion Regulation Scale (DERS) to measure ADHD-like traits and emotion dysregulation, respectively. Results The Inattention subscale of the ASRS was significantly correlated with all subscales of the DERS. Similarly, the Hyperactivity/impulsivity subscale was correlated with all subscales of the DERS except for the Lack of emotional awareness. The Lack of emotional clarity and Difficulties engaging in goal-directed behaviour subscales of the DERS were significant independent positive predictors of ASRS inattention scores. Non-acceptance of emotional responses, Difficulties engaging in goal-directed behaviour, Impulse control difficulties and Lack of emotional clarity subscales of the DERS were significant independent positive predictors of ASRS hyperactivity/impulsivity scores. In other words, as inattention and hyperactive/impulsive symptoms increased in severity, there was a concomitant increase in the severity of most aspects of emotion dysregulation. Conclusions The close association between emotion dysregulation and the classical symptoms of ADHD suggests that they may arise from a common dysfunctional substrate and hence treating emotion dysregulation may provide a novel pathway by which to treat the classical symptoms.
