Evidence-based practices in intellectual disability and behaviour disorders

Abstract

Applied behaviour analysis methods for the assessment and treatment of behaviour disorders continue to be the focus of research, and continue to result in positive outcomes. Recent data show the value of using applied behaviour analysis technologies as a service model for people with behaviour disorders. Pharmacological treatments, especially risperidone, also have a developing evidence base despite a lack of understanding of their mechanisms of action. A number of questions about behaviour disorders remain unanswered, especially whether early intervention may be effective and their putative relationship with psychiatric conditions.
