Participants with access to clinical populations are completing questionnaires for children in four age groups: –0-2 –3-6 –7-12 –13-18 These can be used as a framework for developing instruments for epidemiological research.

5. 5 What is the purpose of collecting disability data for children Service provision and resource allocation –Unmet need –Less well-developed services for children –16-17 year olds least well served Equalisation of opportunity –schooling –employment Health monitoring of the total population
