CORE-10 information

Although the original launch of the CORE instruments included the two 18 item Short Forms (SF/A and SF/B), it became clear that a major shift was occurring in expectations of the length of measures. It also became clear that in routine practice practitioners were unlikely to want the challenge of found keeping track of which short form to use, week on week. As a result, we created a single shorter short form: the CORE-10. It has proved a very popular measure for sessional use in the UK and increasingly in other countries and languages.

The CORE-10 has no wellbeing items, six problem domain items, three functioning domain items and one risk item; given the small numbers of items, no domain scores are used from the CORE-10.  It can be prorated if only one item is omitted but clearly prorated scores should be interpreted cautiously as omission of any item from a short but broad coverage measure can affect the relationship of a prorated score to a score based on all the items.

Our recommendation is that practitioners should use the CORE-OM at baseline and then switch to the CORE-10 for sessions after that. That enables the computation of a CORE-6D “quality adjusted life year” (QuALY) score at baseline and gives a much broader picture of the baseline state of the client. Where the last session is planned, the CORE-OM should be used for a termination score and, ideally at follow-up sessions if those are routine.
