Clinical Outcomes in Routine Evaluation - 10 (CORE-10)


What it is​

The CORE-10 (Clinical Outcomes Routine Evaluation – 10) is a self-report shortened version of the 34 item CORE-OM assessing the severity of psychological distress. Compared to the CORE-OM, the CORE-10 includes six problem domain items, three functioning domain items and one risk item – omitting wellbeing items. It is recommended that the CORE-OM is administered at baseline and the end of treatment with the CORE-10 used as an intermediary assessment.

How is it used​

  • Can be used with adults (18yrs+)
  • Takes approximately 2mins to complete
  • Asks about psychological distress over the last week
  • Can be used to track treatment progress

Can be used in combination with the CORE-OM and total scores from the CORE-10 and CORE-OM directly compared

What do the scores mean?​

The CORE-10 has 10 items, with all items using the same five level response from 0 (not at all) to 4 (most of the time). The questionnaire is completed in relation to the past 7 days and provides a total score of distress. The total score is scored between 0 and 40 with higher scores reflecting worse distress and are categorised across six levels of severity:

  • Healthy (score of 0 to 6)
  • Low severity (score of 7 to 10)
  • Mild severity (score of 11 of 15)
  • Moderate severity (score of 16 to 20)
  • Moderate to severe severity (score of 21 to 25)
  • Severe severity (score of 26 to 40)

A clinical cut off score of 10 has been recommended with a reliable change index score of 5 points for any change to be classed as reliable. When administered more than once, trends can be viewed across the provided scores to assess change over time.
