The Finnish Clinical Outcome in Routine Evaluation Outcome Measure: psychometric exploration in clinical and non-clinical samples
Sammanfattning
The Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM) is a 34-item self-report
measure designed to monitor changes in psychiatric patients. It has been translated into 25 languages,
including Finnish. This is the first psychometric exploration of Finnish CORE-OM data. The aim of the
study is to examine acceptability, internal consistency and convergent validity of the Finnish CORE-OM
scores. Translation of the CORE-OM from English to Finnish was undertaken according to recommended
protocols. Psychometric exploration was conducted in two samples: psychiatric patients
(N ¼ 201) and non-clinical participants (N ¼ 209). Participation was voluntary and involved completion
of all scales. Convergent validity was tested in terms of the mean score differences between clinical
and non-clinical samples and correlations against the Beck Depression Inventory (BDI) and the
Symptom Checklist (SCL-90). Among the clinical sample, all domains showed good or acceptable
internal reliability. In the non-clinical sample, the alphas of domains were good or acceptable, with
only the alphas of the Risk domain registering as low. There were no marked gender or age effects.
CORE-OM scores correlated strongly with both the BDI and SCL-90, particularly in patients’ data. Some
possible effects of Finnish language were found. The Finnish translation of the CORE-OM is psychometrically
sound and can be recommended for use in Finnish mental health and clinical settings. However,
further investigation in larger and different samples will clarify the generalizability its psychometric
properties. Clinical services are encouraged to contribute to the creation of a collaborative Finnish
CORE practice research network.
