Introduction: Chronic obstructive pulmonary disease (COPD) is a major global health problem causing high morbidity and mortality. Easy to apply, cost-effective, and available COPD severity measures are required in rural areas. Objective: To assess the validity and reliability of the COPD Severity Score (COPDSS) in Colombian patients attended in primary care. Materials and methods: A cross-sectional study was conducted in a sample of 100 patients diagnosed with COPD according to GOLD guidelines. Convergent validity was assessed by correlating the COPDSS results with other important variables such as those assessed through the Chronic Respiratory Disease Questionnaire (CRQ) and the forced expiratory volume in one second (FEV1). Results: The COPDSS showed a significant correlation with the FEV1 (r=-0.33), with the CRQ (r=-0.57) and its dimensions: Dyspnea (r=0.51), fatigue (r=0.53), emotional function (r=0.43), and disease control (r=0.50). The factor analysis identified a single factor with a cumulative variance of 59.1%. The internal consistency analysis showed an adequate Cronbach’s alpha of 0.76. Conclusions: The use of the COPDSS as an assessment test for COPD patients in Colombia showed adequate validity, reliability, and easy application in primary care.
