Abstract copyright UK Data Service and data collection copyright owner.The National Child Development Study (NCDS) is a continuing longitudinal study that seeks to follow the lives of all those living in Great Britain who were born in one particular week in 1958. The aim of the study is to improve understanding of the factors affecting human development over the whole lifespan. The NCDS has its origins in the Perinatal Mortality Survey (PMS) (the original PMS study is held at the UK Data Archive under SN 2137). This study was sponsored by the National Birthday Trust Fund and designed to examine the social and obstetric factors associated with stillbirth and death in early infancy among the 17,000 children born in England, Scotland and Wales in that one week. Selected data from the PMS form NCDS sweep 0, held alongside NCDS sweeps 1-3, under SN 5565. Survey and Biomeasures Data (GN 33004):To date there have been nine attempts to trace all members of the birth cohort in order to monitor their physical, educational and social development. The first three sweeps were carried out by the National Children's Bureau, in 1965, when respondents were aged 7, in 1969, aged 11, and in 1974, aged 16 (these sweeps form NCDS1-3, held together with NCDS0 under SN 5565). The fourth sweep, also carried out by the National Children's Bureau, was conducted in 1981, when respondents were aged 23 (held under SN 5566). In 1985 the NCDS moved to the Social Statistics Research Unit (SSRU) - now known as the Centre for Longitudinal Studies (CLS). The fifth sweep was carried out in 1991, when respondents were aged 33 (held under SN 5567). For the sixth sweep, conducted in 1999-2000, when respondents were aged 42 (NCDS6, held under SN 5578), fieldwork was combined with the 1999-2000 wave of the 1970 Birth Cohort Study (BCS70), which was also conducted by CLS (and held under GN 33229). The seventh sweep was conducted in 2004-2005 when the respondents were aged 46 (held under SN 5579), the eighth sweep was conducted in 2008-2009 when respondents were aged 50 (held under SN 6137) and the ninth sweep was conducted in 2013 when respondents were aged 55 (held under SN 7669). Four separate datasets covering responses to NCDS over all sweeps are available. National Child Development Deaths Dataset: Special Licence Access (SN 7717) covers deaths; National Child Development Study Response and Outcomes Dataset (SN 5560) covers all other responses and outcomes; National Child Development Study: Partnership Histories (SN 6940) includes data on live-in relationships; and National Child Development Study: Activity Histories (SN 6942) covers work and non-work activities. Users are advised to order these studies alongside the other waves of NCDS.From 2002-2004, a Biomedical Survey was completed and is available under End User Licence (EUL) (SN 8731) and Special Licence (SL) (SN 5594). Proteomics analyses of blood samples are available under SL SN 9254.Linked Geographical Data (GN 33497): A number of geographical variables are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies. Linked Administrative Data (GN 33396):A number of linked administrative datasets are available, under more restrictive access conditions, which can be linked to the NCDS EUL and SL access studies. These include a Deaths dataset (SN 7717) available under SL and the Linked Health Administrative Datasets (SN 8697) available under Secure Access.Additional Sub-Studies (GN 33562):In addition to the main NCDS sweeps, further studies have also been conducted on a range of subjects such as parent migration, unemployment, behavioural studies and respondent essays. The full list of NCDS studies available from the UK Data Service can be found on the NCDS series access data webpage.  How to access genetic and/or bio-medical sample data from a range of longitudinal surveys:For information on how to access biomedical data from NCDS that are not held at the UKDS, see the CLS Genetic data and biological samples webpage.Further information about the full NCDS series can be found on the Centre for Longitudinal Studies website. 

NCDS8: The eighth sweep of NCDS was conducted in 2008-2009, when respondents were aged 50 years. The core aims of the NCDS8 were to update the life history information collected in previous studies and to collect new information to help understand the ageing process. Many of the questions in the NCDS8 follow-up had been asked in earlier waves of the NCDS and the BCS, which will allow for the making of comparisons both across the sweeps of NCDS and with the BCS cohort. The 2008-2009 survey is comprised of the following elements:a 55 minute a 'core' interview (included a Computer Assisted Personal Interview (CAPI); Computer Assisted Self Interview (CASI); a series of cognitive assessments)a paper questionnaireEdition history: The NCDS8 has been deposited at the UK Data Archive in stages. For the first Archive edition (March 2009) an interim data file was deposited, based on 2,997 interviews completed between August and December 2008. This file comprised a subset of the full list of variables. The second Archive edition (the first full sample edition) was released in February 2010. This deposit included responses to the bulk of the questions fielded to cohort members in 2008-2009. The variables that were not included in this file were essentially those that required the most complex post-fieldwork editing in order to make them usable, mostly those that related to the four 'history' modules; housing history, relationship history, fertility history and economic activity history. In addition, variables relating to absent children, older children and specific details of recently-achieved qualifications were not included (although a series of derived summary variables relating to highest qualification were). For the third Archive edition (October 2012), the final version of NCDS8 was deposited. Two files, 'ncds_2008_followup.sav' and 'ncds8_unfolding_brackets.sav' replaced the previous single data file, a new User Guide replaced the previous version, and the Technical Report and Appendices were added to the documentation. For further details, see the User Guide.

Main Topics:

CAPI interview: The CAPI interview collected updated information about household composition, housing, relationships, births and other pregnancies, periods of lone parenthood, adopted children, absent and older children, parents, family income, economic activity, education and qualifications, work-related training, use of computers, health, smoking, drinking, exercise, height, weight, social participation and social support. CASI interview: The CASI interview collected information on voting behaviour and party support, experience of symptoms of the menopause, problematic drinking behaviour, well-being, relationship satisfaction, domestic division of labour, job commitment, attitudes towards pensions and retirement, childhood, efficacy and life satisfaction. Standard Measures The interview included several established scales: Kanungo’s Job Involvement Scale; the AUDIT (Alcohol Use Disorders Identification Test) and the Malaise The cognitive assessment module is comprised of four tasks: Word list recall test; Animal naming task; Letter cancellation task; Delayed word list recall test.
