CORE measures

These are a set of self-report questionnaires designed primarily to measure change in therapies. The first was the 34 item CORE-OM (OM for Outcome Measure) for adults, that was launched in 1998 with two 18 item short forms (CORE-SF/A and CORE-SF/B) intended for alternating use where a shorter form was wanted for sessional/weekly use. A 14 item GP-CORE for general population surveys, omitting the risk items and higher tuned items was derived from the CORE-OM (first paper 2005) as was the CORE-10 (first paper in 2013), a simpler and shorter alternative to the SFs for sessional use. A 10 item YP-CORE modelled on items from the CORE-OM adapted for adolescents was added (first paper 2009). An LD-CORE inspired by the CORE-OM but including items specifically developed for and with adults with learning disabilities was another extension of the family of measures. That exists in 14 and 30 item versions and uses images as well as simple text for the items and a three rather than five level response system. The measures have been translated into many languages and form the heart of the CORE system though that, see https://www.coresystemtrust.org.uk/ is more than the measures including a philosophy of routine change measurement. (The acronym stands for “Clinical Outcomes in Routine Evaluation”.)
