Abstract
The Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM) is a scale designed as a multi-theoretical and multi-diagnostic measure of general psychological distress. It can be used at all levels of psychological care, from triage to monitoring the effects of psychotherapy. The aim of this study was to assess the psychometric properties of the Croatian version of the CORE-OM questionnaire in an adult sample and to determine the cut-off score. The study included a total of 608 participants divided into non-clinical (n=425) and clinical (n=183) groups. In addition to the CORE-OM questionnaire, the Beck Depression Inventory-II and the State-Trait Anxiety Inventory were administered. Analysis revealed a four factor structure with a higher order factor corresponding to the original structure, suggesting that this questionnaire measures the degree of general psychological distress from which it is also possible to determine in which areas this distress is particularly pronounced. Satisfactory internal consistency and test-retest reliability, as well as a good convergent validity, were confirmed. On the basis of ROC analysis, a cut-off score of 1.38 was determined. For clinicians, the CORE-OM can be used to assess general distress. However, it should be used in combination with other, more specific measures to further examine the expression of certain mental disorders. In research, the CORE-OM can be used as a reliable and valid measure of the presence and intensity of psychopathological disturbances.
