The purpose of this case study was to demonstrate the success of a multicomponent intervention to reduce the threatening and aggressive behaviors of a middle school student with Asperger's syndrome. The author provides information pertaining to the student and details the procedures for developing a packaged intervention. Results of this approach, although not considered to be rigorous research, demonstrate that an intervention that is based on evidence-based practices can be effective at remediating even the most severe behavioral problems demonstrated by an individual with Asperger's syndrome. In particular, data indicated that a combined intervention approach significantly increased the student's overall level of functioning and improved the perception of the student's behavior by teachers and administrators. The author offers implications for practice and future research. (Contains 4 figures and 3 tables.)
