Multimodal Assessment of Emotion Dysregulation in Children with and without ADHD and Disruptive Behavior Disorders

We sought to explore if specific domains of emotion dysregulation (emotion regulation [EREG], emotional reactivity/lability [EREL], emotion recognition/understanding [ERU], and callous-unemotional [CU] behaviors) were uniquely associated with diagnostic classifications.

This study utilized a multimodal (parent/teacher [P/T] reports and behavioral observations) approach to examine emotion dysregulation in a sample of young children (68.7% boys; mean age = 5.47, SD = 0.77, 81.4% Latinx) with attention-deficit/hyperactivity disorder (ADHD Only; n = 46), ADHD + disruptive behavior disorders (ADHD+DBD; n = 129), and typically developing (TD) children (n = 148).

All three diagnostic groups were significantly different from one another on P/T reports of EREG, EREL and CU. For the ADHD+DBD group, P/T reported worse EREG and EREL, and higher mean scores of CU, compared to both ADHD Only and TD groups. The ADHD+DBD group also performed significantly worse than the TD group (but not the ADHD Only group) on observed measures of EREG, EREL and ERU. P/T reported EREG, EREL and CU for the ADHD Only group were significantly worse than the TD group. Using multinomial logistic regression, P/T reported EREG, EREL, and CU were significantly associated with diagnostic status above and beyond observed measures of emotion dysregulation. The model successfully classified children with ADHD+DBD (91.3%) and TD (95.9%); however, children in the ADHD Only group were correctly identified only 45.7% of time.

Our findings suggest that measures of emotion dysregulation may be particularly helpful in correctly identifying children with ADHD+DBD, but not necessarily children with ADHD Only.
