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 รก 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.
