The classification of problem behaviour in Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD)

Problem behaviour is common among adults with learning disabilities, often to an extent that it impacts upon the functioning and social inclusion of the individual, and of the individualʹs family and immediate social network. However, most approaches to the classification and diagnosis of psychiatric disorder among people with learning disability do not deal with problem behaviour as a diagnosis. The recent innovation of the Diagnostic Criteria for Psychiatric Disorders for Use with Adults with Learning Disabilities/Mental Retardation (DC-LD) includes diagnostic criteria for problem behaviour. The background and the thinking behind these criteria are reviewed. It is proposed that the adoption of such criteria offers the possibility of improved services for the individuals concerned, with resultant improvements in their adaptation and social inclusion.
