Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder marked by a constellation of inattentive and/or hyperactive/impulsive symptoms. Accurate diagnosis of ADHD helps individuals find the treatment they need, but what type of provider should someone reach out to for ADHD assessment? Many pediatricians use surveys, such as the NICHQ Vanderbilt ADHD Assessment Scale, to gather data from multiple sources. Since ADHD is not a disorder that requires specific assessment practices, there are different professional opinions on the role of psychology in ADHD assessment. The value of a psychological evaluation lies in the examination of differential diagnoses and comorbid conditions of ADHD.
