Study Number 7464 - Millennium Cohort Study: Age 11, Sweep 5, 2012
DATA CURATION PROCEDURES
Data acquired for the UK Data Service collection undergo rigorous and comprehensive curation prior to publishing and release. This ensures that data, documentation and metadata are processed and published to the highest standard possible, both for ease of use in secondary analysis and for archival preservation.
The curation procedures carried out depend on the individual nature of each dataset and document, but as a general guide the following tasks are always undertaken:
- Disclosure review - if data confidentiality issues are identified, they are resolved in consultation with the data depositor;
- Data are checked for consistency and accuracy – for example undocumented/out-of-range codes;
- Variable and value label metadata are checked and enhancements undertaken as necessary;
- Multiple data and documentation formats may be generated for dissemination and preservation;
- A catalogue metadata record is generated and a Digital Object Identifier (DOI) is assigned to the study where appropriate.
- Where the data are made available for online analysis, in addition to the checks above, question text may be added alongside variables and other enhancements made.
DATA AND DOCUMENTATION NOTES
{DataDocumentationNotes}
NEW EDITION INFORMATION
For the 6th edition (October 2022), a new date file mcs5_family_interview, has been added due to the family level data being split out from the parent-level data to make future merging with MCS8 onwards easier. Two data files (mcs5_parent_interview and mcs5_parent_cm_interview) have been updated to include variables that were missed from the previous edition due to a technical error (mainly from the income and employment module). There has been some further restructuring of datasets (parent responses moved out of mcs5_cm_interview and placed into mcs5_parent_cm_interview). Derived SDQ scores have been added to mcs5_cm_derived and a derived Kessler score has been added to mcs5_parent_derived. In addition, the number of cases in the mcs5_hhgrid data file have changed due to updates. Users are advised to check the Longitudinal Family File held under SN 8172 for the sample size.
