Abstract:
Arildskov et al. (2021) provide compelling evidence regarding the importance and nature of functional impairment in advancing diagnostic assessment and treatment of attention-deficit/hyperactivity disorder (ADHD). Their findings indicate that (a) ADHD is dimensional for both symptom severity and impairment, (b) symptoms and impairment are related but separate constructs, (c) diagnostic assessment should focus equally on symptoms and impairment, and (d) the symptom threshold for ADHD diagnosis is arbitrarily defined with respect to presence of impairment. Results from this study can be extended to raise the profile of functional impairment in research and clinical practice in terms of diagnostic assessment, treatment outcome measurement, improvements to diagnostic systems, and advancements in our understanding of ADHD as a disorder.
