Abstract copyright UK Data Service and data collection copyright owner.CLOSER (Cohort and Longitudinal Studies Enhancement Resources) aims to maximise the use, value and impact of longitudinal studies, both at home and abroad. Bringing together leading UK longitudinal studies, the British Library and the UK Data Service, CLOSER works to stimulate interdisciplinary research, develop shared resources, provide training, and share expertise. Resources available from CLOSER include harmonised datasets (developed to facilitate cross-study comparisons) and CLOSER Discovery (a search engine that enables researchers to search and browse questionnaires and data from different longitudinal studies). CLOSER’s website also includes a range of training materials focused on longitudinal studies and data. CLOSER is funded by the Economic and Social Research Council (ESRC) and is based at the UCL Institute of Education.CLOSER Work Package 20 has generated harmonised measures of mental health at age 10/11 in the National Child Development Study (NCDS), 1970 British Cohort Study (BCS70), the Avon Longitudinal Study of Parents and Children (ALSPAC), and the Millennium Cohort Study (MCS).

The Harmonised Mental Health Measures at Age 10/11 in Selected British Cohorts: National Child Development Study provides the harmonised data on mental health for NCDS.
