CORE Measurement Tools

The CORE Outcome Measure ('Parent' measure)

The CORE-OM is a 34-item generic measure of psychological distress, which is pan-theoretical (i.e., not associated with a school of therapy), pan-diagnostic (i.e. not focused on a single presenting problem), and draws upon the views of what practitioners considered to be the most important generic aspects of psychological wellbeing health to measure. The CORE-OM comprises 4 domains:

  1. Well-being (4 items)
  2. Symptoms (12 items)
  3. Functioning (12 items)
  4. Risk (6 items)

It takes between 5-10 minutes to complete.

CORE - 18A , CORE - 18B Short Forms A and B (Session-by-session repeated administration)

Two parallel, 18 item psychometrically-balanced measures for use at alternate therapy sessions and which together make up all the original items of the full CORE-OM. The use of two short forms at alternate sessions rather than the CORE-OM measure at every session reduces memory effects. Due to administrative complexities, repeated administration of the two short forms is usually used only in research studies. In routine therapy practice, session by session measurement usually involves CORE-10 or CORE-5 (see below).

CORE - 10  (Session-by-session monitoring, review or quick initial assessment)

A short, 10 item version of the CORE-OM to be used as screening tool and outcome measure when the CORE-OM is considered too long for routine use. Items cover anxiety (2 items), depression (2 items), trauma (1 item), physical problems (1 item) functioning (3 items - day to day, close relationships, social relationships) and risk to self (1 item). The measure has 6 high intensity/severity and 4 low intensity/severity items.

CORE - 5 (Session-by-session monitoring)

CORE-5 comprises 5 items drawn from the CORE-OM and was designed to provide a concise instrument for practitioners to monitor ongoing progress session by session as a briefer alternative to CORE-10. Items cover anxiety, depression, and functioning.

CORE - GP  General Population

(For use with general or student populations)

A short, 14 item measure derived from the CORE-OM suitable for use with general populations, including students. In contrast to the CORE-OM, CORE-GP comprises low intensity, low risk items and over half the items are positively keyed. These aspects increase its acceptability in a non-clinical population.

YP - CORE  Young Person's CORE

A 10-item measure derived from the CORE-OM and designed for use in the 11-16 age range. Structure is similar to that of the CORE-OM but with items rephrased to be more easily understood by the target age group

CORE - LD  Learning Disabilities

CORE-LD is being developed by therapists and adults with learning disabilities in Scotland and England. The measure includes simplified items from the CORE-OM selected by therapists and also by adults with learning disabilities. It includes new items designed to cover the major issues they face that are not in the CORE-OM.

CORE Goal Attainment Form

The Goal Attainment Form allows for client/patient defined difficulties or goals to be identified at the outset of therapy, and on termination, to identify the degree to which therapy has helped with each. It further asks for a description of positive aspects of therapy, areas that remain unresolved, and the client/patient's overall satisfaction and inclination to recommend the service.

ARM-5 Therapeutic Alliance

A five item measure derived from the 28 item Agnew Relationship Measure to assess the strength of the therapeutic relationship between clients and their therapists.
