How Can Clinicians Determine Whether a Child's Inattentive or Hyperactive-Impulsive

Multiple Choice

How can clinicians determine whether a child's inattentive or hyperactive-impulsive symptoms are developmentally inappropriate or excessive?

A) Clinicians don't need to determine this; they simply need to determine whether the symptoms interfere with the child's everyday functioning.
B) Clinicians can observe the child's classmates; if the child in question is significantly more inattentive or hyperactive-impulsive than his or her classmates on a given day, an ADHD diagnosis would be appropriate.
C) Clinicians can ask children to rate their own behavior; because children are generally credible and valid at self-report, this would be sufficient for diagnosis.
D) Clinicians can administer norm-referenced rating scales to parents and teachers; very high symptom ratings might qualify the child for a diagnosis of ADHD.
