Validation and adaptation to Spanish of the EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI).

ABSTRACT

INTRODUCTION AND OBJECTIVES: Sjögren's Syndrome (SS) is an autoimmune disease with a wide spectrum of clinical manifestations that can have an important impact on the patient's quality of life. To make an objective evaluation of the components of the disease, clinimetric tools such as the ESSPRI have been designed. The objective of this study is to adapt this scale to the Spanish language. MATERIALS AND METHODS: This is a cross-sectional study to validate clinimetric scales, carried out in Cali, Colombia. A translation of the original English version of ESSPRI into Spanish was made and applied to patients with SS, as well as PROFAD and ESSDAI, as an activity marker. The reliability index of the questionnaire in Spanish with Cronbach's alpha coefficient and Spearman's correlation coefficient were calculated to compare the scales. Demographic, clinical and laboratory characteristics were also evaluated. RESULTS: ESSPRI, PROFAD and ESSDAI were applied to 42 patients with SS, 97.62% were women. The average result of the ESSPRI was 5.8 (± 4.6), with a reliability coefficient of .8034 and a correlation with PROFAD of .5800 (p=.0001), and of -.0848 (p=.593) with ESSDAI. DISCUSSION AND CONCLUSIONS: Reliability with the applied version of ESSPRI in Spanish was adequate. A discrepancy was found between this scale and ESSDAI, which highlights the importance of applying both tools to ensure objective monitoring of disease control and its impact on the quality of life of patients with SS.
