Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in children, with an estimated 9.8% of U.S. children being diagnosed between ages 3 and 17. However, sometimes ADHD is missed during childhood, with many adults exhibiting symptomatic ADHD. There remains consistent and significant disparities in the diagnosis and conceptualization of ADHD that span age, gender, and racial and ethnic backgrounds. This workshop will explore current practices within assessment psychology to help clinicians identify ADHD characteristics that may or may not align with the DSM-V criteria, suggest ways to promote additional exploration, and highlight when an extended evaluation is necessary.
