Reliability of the Scoliosis Research Society-22 Patient Questionnaire (Italian version) in mild adolescent vertebral deformities.

Abstract

The SRS-22-I was found to be reliable for young patients with mild vertebral deformities of different type. Lack of reliability for questions 12 and 21 should be better understood. Until now the psychometric properties of SRS-22 questionnaire have been evaluated only in USA populations, and in idiopathic scoliosis. Moreover, only one study has been proposed including patients with mild idiopathic scoliosis. This, together with the non-parametric statistical analysis used, could explain the high ceiling and floor effects we found in our data.
