Approximately 10 percent of children and adults with intellectual disabilities, autism or other neurobehavioral disorders display severe behavior problems such as self-injury, aggression, or property destruction. The Neurobehavioral Unit (NBU) at Kennedy Krieger Institute provides a continuum of care for these individuals that includes consultation services, a 16-bed inpatient program, outpatient follow-up, and intensive outpatient services. The primary approach used is applied behavior analysis, characterized by the application of principles of behavior derived through laboratory research, the objective measurement of behavior, and the systematic analysis of relations between behavior and environmental events. The NBU is recognized as one of the leading programs in the nation for providing intensive behavioral treatment to individuals with severe behavior disorders and developmental disabilities as well as for offering advanced training in applied behavior analysis.
The individuals served on the NBU frequently present rare behavior disorders that require innovative treatment approaches, so the NBU faculty and staff must constantly design new assessment and treatment procedures to meet the varied needs of their patients. Dr. Hagopian's main research interests are in assessment and treatment of self-injurious behavior, severe behavior disorders, anxiety disorders, and the application of operant learning paradigms to examine clinical problems including austim and anxiety.
