[Interrater reliability for diagnosis in adults of attention deficit hyperactivity disorder and oppositional defiant disorder using K-SADS-E].

The diagnosis of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) in adults lacks adequate assessment instruments. The aim of this investigation is to evaluate the interrater reliability of the sections of K-SADS-E adapted for the diagnosis of these disorders among adults. The adaptations were limited to asking questions directly to the patient, investigation of a later onset of symptoms, and asking for adult specific symptoms.
