Adult ADHD Clinical Diagnostic Scale (ACDS) V 1.2:

This is a semi-structured interview that establishes both current adult symptomatology and the presence of any ADHD symptoms in childhood. The 18 items in the ACDS match the 18 symptom domains of ADHD noted in DSM-IV. As the SCID does not cover ADHD it is used in conjunction in order to help make or rule out this diagnosis.

Domains Assessed: Attention Problems and Hyperactivity

Note: This semi-structured interview is administered to all adult participants ages 18-85 years old.
