The Anxiety and Related Disorders Interview Schedule for DSM-5 (ADIS-5) Clinician Manual accompanies both the Adult and Lifetime versions of the ADIS-5 Client Interview Schedules. The interview schedules are designed to diagnose anxiety, mood, obsessive-compulsive, trauma, and related disorders (e.g., somatic symptom, substance use) and to permit differential diagnosis among these disorders according to DSM-5 criteria (American Psychiatric Association, 2013). The Clinician Manual provides information for the clinician about uses of the ADIS-5, changes introduced in the ADIS-5, coverage of the ADIS-5, organization of diagnostic sections, how to administer the ADIS-5, and more.
