Attention Deficit/Hyperactivity Disorder (ADHD) Detail  
The scales described below can help identify a variety of symptoms affecting children and adolescents. Do not assume that a particular "score" on any rating scale or screening tool means a child has a particular disorder-these instruments are only one component of an evaluation. Diagnoses should be made only by a trained clinician after a thorough assessment. Symptoms suggestive of suicidal or harmful behaviors warrant immediate attention by a trained clinician.
