The Anxiety Disorders Interview Schedule for DSM-IV (ADIS-IV) is a structured interview designed to assess for current episodes of anxiety disorders, and to permit differential diagnosis among the anxiety disorders according to DSM-IV criteria. The ADIS-IV also provides sufficient information to permit functional analysis of the anxiety disorders. In addition, sections to assess current mood, somatoform, and substance use disorders are included because of their high comorbitidy rate with anxiety disorder and because the presenting symtomatology of these disorders is often quite similar to that of the anxiety disorders. The ADIS-IV also contains screening questions for psychotic and conversion symptoms and familial psychiatric history. A more detailed section is included to ascertain the patient's medical and psychiatric treatment history. Finally, with the exception of Axis II disorders, the ADIS-IV permits the use of the DSM-IV multiaxial system. The Anxiety Disorders Interview Schedule for DSM-IV: Adult Version (ADIS-IV-L) contains all of the sections included in the ADIS-IV. However, unlike the ADIS-IV, the ADIS-IV-L has been designed to establish past (lifetime) diagnoses as well. The ADIS-IV=L also contains a Diagnostic Timeline to assist in the determination of the onset, remission, and temporal sequence of disorders. Price is for a set of 10.
