ABSTRACT
The Eyberg Child Behavior Inventory (ECBI) and the Sutter-Eyberg Student Behavior Inventory (SESBI) are widely used to measure disruptive behavior problems in children and adolescents (e.g., oppositional defiant disorder symptoms, attention-deficit/hyperactivity disorder symptoms, and conduct disorder symptoms). Previous normative studies on the ECBI and SESBI, however, suffer from a variety of limitations. This article addresses these limitations by providing more useful normative information on the ECBI (parent) and SESBI (teacher) rating scales. Study one provides normative information on the ECBI for 2,527 2-to 17-year-old children and adolescents. Study two provides normative information on the SESBI for 1,286 kindergarten through sixth grade children. Clinicians and researchers should find this new normative information on the ECBI and SESBI useful for screening purposes. This new normative information will also help to determine the clinical significance of treatments for disruptive behavior problems where the ECBI and SESBI are used as outcome measures.
