The purpose of this study is to translate the WORC index into Spanish and to evaluate its reproducibility and internal consistency in patients with RCD.  Methods: Following guidelines from literature, the WORC index was translated. Sixty patients with RCD were asked to complete the questionnaire. To evaluate reliability, they were asked to answer it for a second time within the next 14 days. The Cronbach&#8217;s &#945; (CA) and the intraclass correlation coefficient (ICC) were calculated to determine test-retest reliability and internal consistency. Bland-Altman plot and reliable change index (RCI) were used to evaluate measurement error.  Results: Cronbach&#8217;s &#945; was 0.96 for the total WORC score (ranges 0.85-0.94 for the five domains). Excellent test-retest reliability was seen with an ICC of 0.98, with the domains ranging between 0.91-0.97. The Bland-Altman plot showed no systematic differences, and the RCI for the total WORC index was 7.6%.  Conclusion: The Spanish version of the WORC index is a valid and reliable tool for evaluating quality of life in patients with RCD and may be used in Spanish speaking countries like Colombia.  Level of evidence: Basic Science Study, Development or Validation of Outcomes Instruments/Classification Systems.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen  Introducción: El Índice de Western Ontario para Manguito Rotador (WORC) evalúa la calidad de vida en pacientes con patología del manguito rotador. El objetivo de este estudio fue traducir la escala al español y evaluar su consistencia interna y reproducibilidad en pacientes con esta enfermedad.  Métodos: Siguiendo las guías de la literatura, se tradujo la escala de WORC y se aplicó a sesenta pacientes con patología del manguito rotador. Para evaluar la confiabilidad, los pacientes debían responder la escala por segunda vez, en un período no mayor a 14 días. Se calcularon el alfa de Cronbach y el coeficiente de correlación intraclase (ICC) para determinar la confiabilidad test-retest y la consistencia interna. El gráfico de Bland-Altman y el índice de cambio confiable (RCI) se usaron para calcular el error de medición.  Resultados: El alfa de Cronbach fue 0,96 para el valor total del WORC (rango de 0,85-0,94 para los cinco dominios). La confiabilidad test-retest fue excelente con un ICC de 0,98 (rango de 0,91-0,97 para los dominios). El gráfico de Bland-Altman no demostró diferencias sistemáticas y el RCI fue 7,6 %.  Conclusión: La versión en español de la escala de WORC es una herramienta válida y confiable para evaluar calidad de vida en pacientes con patología del manguito rotador y puede utilizarse en países de habla hispana como Colombia.  Nivel de evidencia: Estudio de ciencias básicas, desarrollo o validación de instrumentos para medición de desenlaces.]]></p></abstract>
