Normative study of a checklist of emotional and behavioural disturbance in adults with intellectual disability

People with intellectual disability (ID) are three times more likely to suffer mental illness than the general community, making this a bigger problem than schizophrenia. They are a great burden to their carers and cost to the community but their mental health problems remain largely untreated. This study aims to conduct the largest and most comprehensive survey of the mental health of adults with ID that has been undertaken internationally to date. The population will cover the age span of late adolescence (16 years) through the transistion to adult life then through to the elderly. The research will establish the prevalance and nature of mental illness and potential risk factors in large representative population of adults of ID.
