There are a total of 63 items under 5 clinical scales (Inhibition, Emotional Control, Flexibility, Planning and Organization, and Working Memory); three clinical indices (Inhibitory Self-control, Flexibility, and Developing Metacognition); an Executive Function Global Index; and two validity scales (Negativity and Inconsistency).
