Validation and psychometric properties of the Eular Sjögren's Syndrome Patient Reported Index (ESSPRI) into Brazilian Portuguese.
OBJECTIVE
To carry out the cross-cultural adaptation of Eular Sjögren's Syndrome Patient Reported Index (ESSPRI) for Portuguese language and evaluate its psychometric properties.


METHODS
Cross-sectional study of patients with primary Sjögren's syndrome (SS). The psychometric properties (intraobserver reproducibility and construct validity) were studied. In construct validity, ESSPRI was compared with the Patient's Global Assessment (PGA), Profile of Fatigue and Discomfort (Profad), Sicca Symptoms Inventory (SSI) and Functional Assessment of Chronic Illness Therapy (Facit-F). Statistical tests used were:Cronbach's alpha, intraclass correlation coefficient (ICC), Bland-Altman method and Spearman coefficient. A value of p ≤ 0.05 was considered significant.


RESULTS
There was no difference between versions in both languages; thus, a Brazilian consensual version was obtained. All subjects were women aged 49.4 ± 11.6 years, with onset of symptoms of 7.2 ± 5.4 years, and time of diagnosis of 3.0 ± 3.3 years. The mean ESSPRI was 6.87 ± 1.97. The intraobserver reproducibility was high and significant (0.911) and, with Bland-Altman method, there was no systematic bias in the agreement of measures among evaluations. A moderate correlation of ESSPRI with all tested instruments was observed.


CONCLUSIONS
The Brazilian Portuguese version of ESSPRI is a valid and reproducible version.
