Abstract

We identified a subset of impulsive, aggressive children as having symptoms that met criteria for Intermittent Explosive Disorder (IED) using the Interview Module for Intermittent Explosive Disorder (M-IED). The M-IED was administered to 34 children and adolescents between the ages of 10 and 17. These data provide initial evidence for the M-IED as a useful instrument in the diagnosis of IED in adolescents. The M-IED displayed a high level of inter-rater reliability and adequate test-retest reliability. Construct validity was supported by the fact that the subjects with IED symptomatology had significantly more lifetime aggression, oppositionality, inattention and hyperactivity/impulsivity compared to community controls. In addition, the subjects with IED symptomatology had a significantly greater number of episodes of lifetime physical aggression and documented episodes of aggression while in residential treatment compared to psychiatric controls. The subjects with IED symptomatology had a greater number of positive screening questions for DSM-IV diagnoses using the Swanson, Nolan and Pelham questionnaire (SNAP-IV), particularly those related to IED and posttraumatic stress disorder than psychiatric controls.
