Abstract

CAMARINI, Paula M. F. et al. The Brazilian version of the SRS-22r questionnaire for idiopathic scoliosis. Braz. J. Phys. Ther. [online]. 2013, vol.17, n.5, pp.494-505.  Epub Sep 10, 2013. ISSN 1413-3555.  https://doi.org/10.1590/S1413-35552012005000108.

BACKGROUND:

The SRS-22r questionnaire is a well-accepted instrument used to measure health-related quality of life in patients with idiopathic scoliosis. No validated tool exists in Brazil for idiopathic scoliosis, and the use of the SRS-22r in non-English Laguage contries requires its transcultural adaptation.

OBJECTIVE:

The objective of this study was to culturally adapt the translated Brazilian version of the SRS-22r questionnaire and to determine its reliability using statistical tests for internal consistency and test-retest reliability.

METHOD:

The transcultural adaptation process was carried out according to the recommendations of the American Academy of Orthopedic Surgeons. The pre-final version was administered to 44 patients with idiopathic scoliosis. The mean age of the participants was 18.93 years and the mean curve magnitude was 54.6°. A subgroup of 30 volunteers completed the questionnaire a second time one week later to determine the scale's reproducibility. Internal consistency was determined using Cronbach's alpha coefficient, and the test-retest reliability was determined using the Intraclass Correlation Coefficient (ICC).

RESULTS:

No floor effects were observed using the Brazilian version of the SRS-22r. Ceiling effects were observed in the Pain and Satisfaction with Management domains. The internal consistency values were very good for 3 domains and good for 2 domains. The ICC values were excellent for all domains.

CONCLUSIONS:

The high values of internal consistency and ICC reproducibility suggest that this version of the questionnaire can be used in Brazilian patients with idiopathic scoliosis.
