Validación de la versión en español para Colombia de la escala ASES

Abstract

Introduction: the ASES (American Shoulder and Elbow Surgeons) score, is a measurement tool developed in English for evaluating function around the shoulder. It has been used since 1993 in its original language. It is made up of demographic data, a medical evaluation section and another section self-completed by the patient. The aim if the study was to translate the ASES score to Colombian Spanish and validate it.

Materials and methods: this is a translation and validation study of Spanish of the ASES score. Patients with shoulder problems were included between December 2015 and March 2016. Patients answered the score twice, during the first consultation and again 7-14 days after. Statistical analysis was performed with Stata 13.0. Cronbach's alpha (AC) and intraclass correlation coefficient (ICC) were calculated to determine internal consistency and test-retest reliability. The Bland-Altman plot was used to determine the measurement error.

Results: sixty-five patients were included in the study. The first cause of consultation was rotator cuff tear (27%). Cronbach's alpha was 0.76 and the intraclass correlation coefficient was 0.74. The Bland-Altman showed absence of systematic error.

Conclusion: the Colombian Spanish version of the ASES score is a valid and reliable tool to assess the quality of life in patients with shoulder pathology and can be used in Colombia on Spanish speaking patients.
