Outcome Measure Analysis
Independent Data report prepared by Elspeth Twigg, CORE IMS Research Lead
February 2014
The Sample
Because the assessment date field was not routinely completed, clients were filtered by post session
date. The sample consisted of 19 clients whose post session date lay between 1/10/12 and
31/12/13. 13 clients were inpatients and 6 outpatients.
[Khiron House note: outpatients participated in this study voluntarily and so only a small sample was
collected. This will be improved for 2014]

Since all of the clients in the sample had Post session dates, all must have been assessed and thus
should have had an assessment outcome.

The ratio of female to male clients was 79:21, with the proportion being slightly higher for
outpatients (83%) than for inpatients (77%).

Of the 13 inpatients, 12 (92%) were above the clinical cut-off pre-therapy and 1 (8%) was below. All
of the 6 outpatients had scores above the clinical cut-off before therapy.
Pre-post analysis
Pre-Post outcome measure completion
All clients in the sample had pre- and post-therapy OM data. However, this is likely to be due in part
to the fact that clients were filtered by Post session date. It is highly likely that other clients were
also seen in the period but not included in the sample because the relevant data fields had not been
completed.
[Khiron House note: All clients who had completed at least 2 outcome measures and were no longer
in treatment at 31/12/13 are included in this study.]
Pre-Post outcome measure score change
17 clients had pre-post CORE-OM data.

Mean (SD)
21.3 (6.12)
15.1 (5.79)
6.2 (4.16)
The average change in score for the inpatients in the sample who had CORE-OM data pre- and posttherapy was a reduction of 6 points.
Outpatients (n=5)

Mean (SD)
21.8 (5.05)
14.7 (9.69)
7.1 (7.59)
Outpatient clients with pre-post CORE-OM data showed an average reduction of 7 points.
Outcome Measure analysis
Reliable improvement
A reliable change in score is a statistically significant change in score between the start and end of
treatment. That is, the change in score is not likely to be due to random fluctuations in score over
time. The threshold levels for reliable change are 5 or more points in CORE-OM clinical score, or 6 or
more points in CORE-10 clinical score.
Once again, analysis was only conducted on those clients with pre- and post-therapy outcome
measure data.

We can see from the reliable change rates that a substantial proportion of inpatients (62%) showed
reliable improvements in score between the start and end of treatment.
A similar proportion of outpatient clients (66%) showed reliable improvements in score between
starting and finishing therapy.
Clinical recovery
Clinical recovery is a move from above to below the clinical cut-off (10 for the CORE-OM, 11 for the
CORE-10) between the start and end of end of therapy, and thus a move from a clinical to a nonclinical population. Clients who showed no clinical recovery are those whose scores remained above
cut-off at the end of therapy.
Analysis was only conducted on those clients who have pre- and post-therapy data.

Only 23% of inpatients showed a clinical change from clinical to non-clinical in their outcome
measure scores between the start and end of treatment. This figure was rather higher for
outpatients at 50%. This may in part be due to the high proportion of clients whose scores were
above clinical cut-off pre-therapy.
[Khiron House note: Full clinical recovery is not routinely expected during inpatient treatment. The
goal of inpatient treatment is to improve the client’s condition ready for outpatient treatment.]
