This paper embarks on a descriptive exploration of the relations between ADHD and Complex Trauma among children in an urban psychiatric hospital. To date, these two diagnostic categories have not been examined in concert. This study was based upon chart reviews of 79 children and adolescents who were receiving treatment at an urban children's psychiatric hospital. The Hospitalized Child and Adolescent Trauma and Psychopathology Questionnaire was completed for each participant and information regarding demographics, diagnosis, and complex trauma.
