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