ADIS/CP is a structured interview involving both child and parents designed to assess for current episodes of anxiety disorders, and to permit differential diagnosis among the anxiety disorders according to DSM-IV criteria.

With the interview the disorders are rated with a clinical severity rating (CSR) from 0 (no interference) to 8 (extreme interference) with severity ratings of 4 or above signifying the presence of a clinical disorder.

SCAS is a questionnaire for children and parents assessing the severity of anxiety symptoms broadly in line with the dimensions of anxiety disorder proposed by the DSM-IV. The scale assesses six domains of anxiety including generalized anxiety, panic/agoraphobia, social phobia, separation anxiety, obsessive-compulsive disorder and physical injury fears.

The items are rated on a 4 point scale: 'never','sometimes', 'often', or 'always' to indicate how often each of the items happens. A higher score means worsen of the symptom. Youth version: Min. score 0, max score 135. Parent version: Min. score 0, max score 117
