The Instruments – Clinical Outcomes in Routine Evaluation (and CST)

If you just want to download one or more instruments, go here for PDFs which are available for almost all the instruments and in almost all the completed, approved, translations. Go here for some other formats but I only have very few of the instruments and translations in formats other than PDF. If you need one that isn’t there, contact me to see if I can help you get it.

CORE-OM

The 34 item main “Outcome Measure” (hence “OM”). Please stay with the original name “CORE-OM” rather than “CORE-34”. Designed for adults, probably usable down to about age 16 depending on literacy. The CORE-OM is the root of the short forms:

CORE-SF/A

One of the two original quasi-parallel 18 item forms.

CORE-SF/B

The other of those original short forms.

CORE-10

More recent short form as need for shorter forms grew and it became clear that alternating forms was often impractical.

GP-CORE

Short form for general population survey work. No risk items.

YP-CORE

Form for young people aged 13-17, usable from 11 to 18, psychometric properties and scores vary with age and gender.

LD-CORE

Forms drawing on the CORE-OM design but co-developed with people with learning disabilities, for them.

LD-CORE-15

15 item LD-CORE.

LD-CORE-30

30 item LD-CORE.

The practitioner completed instruments, collectively the CORE-A (A for Assessment). These are designed primarily to collect information giving context in which to interpret self-report measure responses.

CORE-A TAF

(Therapy Asessment Form) – practitioner completed form that gives the crucial initial context to the change measurement

CORE- EoT

(End of Therapy form) – similar form completed at the end of the therapy describing the therapy.
