ARCHIVE DOCUMENTATION

STUDY NO: 4320

STUDY TITLE: OPCS Survey of Psychiatric Morbidity Among Prisoners in
 England and Wales, 1997

Data and documentation received:
------------------------------- 
The dataset was received December 2000 from the Office for National
Statistics, Social Survey Division, London.

The data were received in SPSS 9.0 portable file format,
documentation in MS Word and hard copy format.


Validation and conversion:
--------------------------
Data and documentation have been thoroughly checked for completeness
and accuracy.

All variables are named and values labelled where appropriate, and
are easily identifiable from the documentation.

Hard copy documentation and Word files scanned/converted to Adobe
Acrobat PDF format using Adobe Capture 1.01 (hard copy) and Adobe
Exchange 3.0 (Word files). All documentation was compiled into a
nine-volume User Guide, fully bookmarked, with an index file for
ease of navigation.


Summary of value-added outputs:
------------------------------- 
See above.


Constraints on the reliability and/or usability of the data:
------------------------------------------------------------
During initial file checking, it was noted that the SPSS file
contained three low-level employment variables - occt, occd and indd.
These string variables include very specific individual information
about employment and work prior to prison sentence - occupational
titles (occt), occupational descriptions (occd) and industry
descriptions (indd). This information, used in conjunction with other
variables in the file, could have resulted in the possible
identification of individual respondents. Therefore, the UK Data
Archive has agreed with the depositor to suppress these three
variables from the dataset available to secondary users.

As there are plenty of other variables in the file covering
employment and occupations, such as industry code, 3-digit SOC code,
employment status before prison, etc., the removal of occt, occd and
indd from the file should not unduly limit the usefulness of the data.

The variable lists in the documentation have been amended to note
that the variables occt, occd and indd are missing from the Archive
dataset, but it is possible they may be referred to elsewhere in the
User Guide, and in the published report.


Any outstanding problems or queries:
------------------------------------ 
None noted, but see section above.
