- For the third edition (March 2009), the variable SXCLASS (Sexual orientation) was added to the non-victim form file.
- For the fourth edition (May 2009), a new version of the interpersonal violence (IPV) data file was deposited, with variables PV3a to PV3o corrected. The IPV file is subject to conditional access.
DATA PROCESSING NOTES
Data Archive Processing Standards
The data were processed to the UK Data Archive's A standard. A rigorous and
comprehensive series of checks was carried out to ensure the quality of the data
and documentation.�Firstly, checks were made that the number of cases and
variables matched the depositor's records. Secondly, checks were made that all
variables had variable labels and all nominal (categorical) variables had value
labels. Where possible, either with reference to the documentation and/or in
communication with the depositor, absent labels were created. Thirdly, logical
checks were performed to ensure that nominal (categorical) variables had values
within the range defined (either by value labels or in the depositor's
documentation). Lastly, any data or documentation that breached confidentiality
rules were altered or suppressed to preserve anonymity.
All notable and/or outstanding problems discovered are detailed under the 'Data
and documentation problems' heading below.
Data and documentation problems
Data conversion information
From January 2003 onwards, almost all data conversions have been performed
using software developed by the UKDA. This enables standardisation of the
conversion methods and ensures optimal data quality. In addition to its own data
processing/conversion code, this software uses the SPSS and Stat/Transfer
command processors to perform certain format translations. Although data
conversion is automated, all data files are also subject to visual inspection by
a UKDA data processing officer.
With some format conversions data, and more especially internal metadata (i.e.
variable labels, value labels, missing value definitions, data type
information), will inevitably be lost or truncated owing to the differential
limits of the proprietary formats.�A UKDA Data Dictionary file (in rich text
format), corresponding to each data file, is usually provided for viewing and
searching the internal metadata as it existed in the originating format. These
files are called:
[data file name]_UKDA_Data_Dictionary.rtf

Conversion of documentation formats
Electronic and paper documentation supplied with this study is usually
incorporated into the UKDA User Guide (in PDF format). The conversion programmes
used are the latest versions of Adobe PDF Writer for electronic documentation
and Adobe Paper Capture (Acrobat 'plugin' version) for paper documentation.
Occasionally, some�of the electronic documentation cannot be usefully converted
to PDF (e.g. MS Excel files with wide worksheets) and this is supplied in�a more
appropriate format. All User Guides are fully bookmarked.
