Time: 180 minutes

The Conners Adult ADHD Diagnostic Interview for DSM-IV (CAADID) is a structured interview that supports diagnosing adults with ADHD. It is most effective when used with other types of ADHD measures, such as the CAARS. The use of the CAADID with these other instruments is illustrated by case studies in the CAADID Technical Manual.

Interview Structure

The interview is divided into two parts (Part I & Part II), which are administered separately. Each part take approximately 90 minutes to complete.

Part I is the Patient History Questionnaire, which can be administered as a clinical interview or self-report questionnaire. It contains questions about demographic history of the client, the developmental course of the client's attention problems, associated risk factors, and comorbidity questions.

Part II, the Diagnostic Criteria Interview, is presented in interview format. The clinician uses the information obtained in Part I to assess against DSM-IV criteria for ADHD. Information is also gathered on age of onset, pervasiveness, and level of impairment for any ADHD symptom that is indicated.
