Description
Summary:To examine the psychometric properties of the Spanish version of the 34-item Clinical Outcomes in Routine Evaluation-Outcome Measure questionnaire (CORE-OM). Psychometric exploration was conducted in two samples: non-clinical (  = 706) and clinical (  = 420) participants. The non-clinical sample comprised a subgroup of community members (  = 308) and students (  = 398). The clinical sample consisted of self-reported patients (  = 209) and outpatients (  = 211). The analysis included both internal and test-retest reliability, convergent validity, and principal component analysis. A reliable change index and clinical cut-off scores were established for assessing clinically significant change. The Spanish CORE-OM demonstrated good internal consistency and test-retest reliability, along with satisfactory convergent validity against the 45-item Outcome Questionnaire (OQ-45.2). There were strong differentiations between the clinical and non-clinical samples and the four sample subsets. The outpatient group reported the highest scores, while the community group exhibited the lowest scores. There were no marked gender effects. All observed patterns aligned closely with the established Spanish referential data. Our findings provide support for the utilization of the Spanish CORE-OM as a measure for tracking psychotherapeutic progress in the context of Chile.
