Proposed by the EPA Section on Mental Health and Intellectual Disability -The International Classification of Functioning, Disability and Health (ICF) is a taxonomy of health and health-related domains. It provides a common language and framework for describing the level of functioning of a person within their unique environment. Furthermore, it helps to describe health problems of a person in line with the International Classification of Diseases (ICD-10). ICF aims to provide a patient-centred approach to the assessment and management of people with chronic health conditions, mental disorders and intellectual disabilities (ID) by defining individual therapeutic goals and monitoring functional outcomes. The ICF also plays an important role in psychiatric rehabilitation, describing health problems due to mental illnesses and neurodevelopmental disorders. ICF facilitates a comprehensive multidisciplinary approach to assess an individual’s level of functioning and care. Use of a standardised classification system to assess and document biopsychosocial function helps to further support provision of high-quality individualised health and social care. Furthermore, ICF provides a standardised assessment instrument to determine individual functional needs for the care, rehabilitation and societal integration of individuals with disabilities which is a statutory requirement in many European countries. For example, in Germany, the revision of the Federal Participation Act (BTHG) requires the use of ICF as a standardised assessment instrument for determining individual functional needs of individuals with ID. Main objective of the workshop is to introduce the ICF and discuss its advantages and limitations in clinical practice, research, psychiatric treatment and care of individuals with ID and mental health problems.
