What is the CORE system?
The CORE (Clinical Outcomes in Routine Evaluation) system is a system of measures/instruments, and crucially a philosophy and
set of tools, to help people use these to monitor routine outcome in psychological therapies. Much more extensive
information about it is mounted at the
CORE Information Management Systems (CIMS) Ltd. website. CIMS write the excellent CORE-PC and
beta release CORE-Net software which provide the most comprehensive support for using the CORE instruments and they also provide
support for those programs and for the system generally. A not for profit company: CORE System Trust holds the copyright on the measures.
The CORE system philosophy
The key aim behind the CORE system is to help bridge the researcher/practitioner gap in psychological therapies.
A key part of the philosophy to help this is a "copyleft" attitude to the measures. This means that you can photocopy
or otherwise reproduce on paper the measures/instruments provided that you don't:
This does not allow you to copy the text of the measures into computer programs.
We (CORE System Trust: CST) have given a five year exclusive licence to CIMS to produce a market quality computer program,
which they have done admirably with their CORE-PC program. The exclusive licence has enabled them to have some chance of
recovering their costs for the programming, support and distribution.
- change them in any way (this includes translating them, removing the copyright notice or any other change
- make a profit from the reprinting them (since we want to keep costs to end users to a minimum)
We have strict criteria for translations into other languages but are very keen that the measures/instruments are
translated or that people explore the issues involved with us.
(Do contact me
if you want to discuss this). The translated versions have to be copyright to CST and will be made copyleft for
photocopying or reproduction on paper exactly like the original measures.
Currently an approved translation into Gujarati has been finished and we are various stages of translation, field testing
or generation of referential data on the following languages:
We are currently involved in getting all of these into elegant PDF
format with the derived shortened forms: the SF1 and 2; the CORE-GP (for
general population surveys) and the new 10 and 5 item shortened forms
for screening and very frequently repeated use.

Dutch, Welsh, French, Kannada, German, Spanish, Portuguese, Saami, Tamil
and Japanese, Somali, Arabic, Catalan, Turkish, British Sign Language and Kurdish are all in
if you are interested in helping in any way with translations.

Email me if you need reprints of these. Please
make it clear which you want and give a snail mail address. There are many, many more publications about and
using the CORE instruments and system, see the CIMS website for a much
more extensive and regularly updated list.

Support for therapists and services
A central part of our philosophy for the CORE system was our understanding that many users would need
support in handling their data. We believe this is ideally provided within "Practice Research Networks"
(PRNs). CORE-PC provides superb support for data entry and analysis and for various PRNs based on service type.
Tools & utilities here
We are developing a philosophy for specifics of analysis as so often research analyses are incomprehensible or seem
to practitioners to answer questions of no interest or utility for them or their services. At the same time, most
practitioners and even most service managers are not very familiar with numerical methods for data analysis. We have
a number of presentations and publications in preparation about ways to approach data and our publication (above)
about the late Neil Jacobson and his colleagues' "Reliable and Clinically Significant Change (RCSC)"
methods. One of the more recent presentations which is available is the
powerpoint presentation of the talk I gave at the 2003
Society for Psychotherapy Research
international conference in Weimar about good ways to analyse routine psychological outcome data
(Mounted 30.vi.03, updated 17.viii.03) and a
and the accompanying
I gave|will give at the
5th Conference on Psychiatric Research in the North, Stokmarknes, Norway, 3.ix.03
I am hoping to provide all the S-plus (and R) scripts that produce the graphics in those talks here shortly.
However, for the moment, I have mounted the following rather random resources:
