Krug Asperger’s Disorder Index (KADI)

The Krug Asperger’s Disorder Index (KADI; Krug & Arick, 2003) is a screening instrument for Asperger Syndrome.

Overview

It is also a useful tool for developing goals for intervention. Two forms, elementary (6–12 years) and secondary (12–21 years), cover a wide age range. The KADI is divided into two sections. Section one is a pre-screening tool. Section two consists of additional items, which are completed only if results of the screening tool indicate a need for further assessment.
