Measurement Informed Care in Attention-Deficit/Hyperactivity Disorder (ADHD).

Measurement-informed care is a cornerstone of evidence-based practice and shared decision-making. A structured diagnostic interview specific to ADHD provides a globally agreed-on standard of evaluation. These interviews are accessible in the public domain in multiple languages and are helpful to clinicians new to the diagnosis of ADHD. Broad-based rating scales looking at multiple domains of psychopathology are critical to assuring recognition of comorbid diagnoses, which might otherwise be missed, differential diagnoses, and identification of the most prominent or treatable diagnosis. Recent innovations in computerized adaptive testing have improved the efficiency and accuracy of diagnostic screening. Rating scales specific to ADHD and disruptive behavior disorders establish the severity of the disorder and response to intervention. Age- and gender-normed symptom rating scales for ADHD capture clinically salient differences between what is normative in different demographic groups. An evaluation of functional impairment in ADHD has been critical to understanding the patient's perspective of the presenting problem. Best practice care for ADHD treatment goes beyond improvement to well-defined standards for both symptom and functional remission. Studies of executive function, emotional regulation, mind-wandering, and sluggish cognitive tempo have led to a richer understanding of the breadth and depth of associated deficits commonly experienced by ADHD patients. Psychometrically validated tools are available to complement every aspect of ADHD care and provide global standards for research.
