Using the CORE-10 well
The CORE-10 is the short form of the CORE-OM, developed by Michael Barkham and colleagues and maintained by the CORE System Trust. It is the measure UK counsellors reach for when the PHQ-9 and GAD-7 feel too symptom-specific: ten items covering anxiety, depression, functioning and risk, scored 0 to 4, giving a total from 0 to 40.
The clinical cut-off is 11, and the bands above it run mild, moderate, moderate to severe, and severe. The same rules of interpretation apply as to any snapshot measure: the number is a photograph of a fortnight, not a verdict on a person, and the trend across administrations carries more information than any single reading. A change of 6 points or more meets the CORE-10 reliable change index; less than that is best read as steady.
One item asks about plans to end one’s life, and it needs your eyes every time, whatever the total. A low overall score with anything above zero on the risk item is not a low-risk result; the calculator flags it for exactly that reason.
A licensing note, because most scoring pages skip it: the CORE instruments are © CORE System Trust and are free to reproduce unchanged on a non-commercial basis. This page respects that by not reproducing the items; you score from your own copy and enter the values. Item text and the measure itself are available from the CORE System Trust at coresystemtrust.org.uk.
