Abstract

Background: The Scoliosis Research Society-22r Questionnaire (SRS-22r) is a questionnaire assessing the health related quality of life of patients with scoliosis. Aim of this study was to evaluate the validity and reliability of the Greek Version of the SRS-22r in patients suffering from scoliosis who were treated conservatively.
Methods: The (translated and adapted) Greek versions of the SRS-22r together with the previously validated Short Form-36 questionnaire were mailed to 117 patients suffering from idiopathic scoliosis. Two weeks later, the Greek SRS-22r was mailed to the same patients once again. The internal consistency, reproducibility and concurrent validity were assessed.
Results: Factor analysis revealed a five-factor structure. The study demonstrated high Cronbach á coefficients for all but the "Satisfaction with management" domain, when compared with the original questionnaire. Intraclass correlation was excellent regarding every domain of the SRS-22r. Concerning concurrent validity, one domain had excellent (r=0.75-1), thirteen domains good (r=0.50-0.75) and 16 domains moderate correlations (r=0.25-0.50) when compared with the relevant domains of the SF-36 questionnaire.
Conclusions: This Greek Version of the SRS-22r outcome instrument is a validated questionnaire which can be used to evaluate Greek-speaking patients suffering from Idiopathic Scoliosis who are being treated conservatively.
