Sub-brand to go here What is the potential for a European multi-national cross-cohorts resource 23 June 2010 Jane Elliott Centre for Longitudinal Studies CLS is an ESRC Resource Centre based at the Institute of Education
Outline • What cross-cohort analysis is already taking place? • What are the existing infrastructures and networks? • What are the different models for a multi-national cross cohorts resource? • Questions for discussion
Existing & potential cross-cohort analyses • Comparison of cohorts born at different times in order to understand more about:- • a) Social Change • b) Durability of individual responses under different conditions • Comparison of cohorts born in different places • - environment and health issues • - labour market context • - policy context • - demographic context • Pooling of data to increase power of analyses
British Birth Cohort Studies • Fully representative samples of the British population • Based on one week’s births - approximately 17,000 babies • Followed up from birth into adulthood • Four British Birth Cohort Studies • 1946 : National Survey of Health and Development (MRC funded) • 1958 : National Child Development Study • 1970 : British Cohort Study 1970 • 2000/1: Millennium Cohort Study

What are the existing infrastructures and networks? • Two contrasting examples – Eucconet and HALCyon
The European Child Cohort Network (EUCCONET) • European Science Foundation Funding:- 5 years, from May 2008 to April 2013 • Objectives • identifying cohort expertise in Europe; • sharing knowledge and experience with a broad range of cohort experts, including from outside Europe, and establishing a forum for an easy accessible expertise on these issues in Europe; • offering opportunities to go deeper on the cross-country comparison by sharing tools and questionnaires.
Healthy Ageing Across the Life Course (HALCyon) • HALCyon brings together an interdisciplinary group of scientists working on nine UK cohort studies to understand three aspects of healthy ageing: physical and cognitive capability; psychological and social wellbeing; and the underlying biology of ageing • Eight work packages will investigate how factors like early development, lifetime health, personality and nutrition, and geographical movements influence the process of healthy ageing • Funded under the New Dynamics of Ageing Programme – cross council Research Programme
Possible models for a multinational comparative cohort research resource (1)? • Resource model: • Documentation emphasising common questions and themes • Data harmonisation • Single portal for information on all European cohort studies • Bibliography on existing cross-cohort research • Capacity building in cross national work • Descriptive materials and resources on historical/geographical/policy context • Opportunities for PIs of cohorts to meet and exchange information • Dedicated staff to facilitate the above and provide a resource to others
Possible models for a multinational comparative birth cohort research resource (2)? • Science-led model: • Funding specifically for cross-cohort research projects • Documentation & data harmonisation arising from projects • Website to showcase programme of work • - links to cohort studies used • - papers and working papers on funded projects
Possible models for a multinational comparative birth cohort research resource (3)? • Data collection model: European Cohort • Single centrally coordinated study • Federated studies (with a common core?) • Birth/pregnancy single cohort • Two or three cohorts starting at different ages • Science –led : specific hypotheses • Resource – led: Multipurpose resource
Adding infrastructure to data? • Scale of European cohort could add additional benefits/infrastructure • Development of new data collection technologies • CAPI testing • Documenting and subseting data • Collection of retrospective life history data • Instrument specification • Interviewer training and acreditation • Safe settings/methodologies for links to administrative and register data • Biological specimens – storage and retrieval
Cohorts and Panels? • Cohort • Individual focus: larger sample more focussed data collection • Cradle to Grave: biomedical focus • Initial recruitment & retention • Triangulated data – teachers, medical examinations
Questions for discussion • What are the scientific gains to be made from a multinational comparative birth cohort research resource? • Should it focus exclusively on recent birth cohorts? • How might such a resource be structured? • What sort of resources are needed to create this?
