Turkish Validity and Reliability Study of Scoliosis Research Society-30 Questionnaire in Adolescent Idiopathic Scoliosis Patients

Abstract

Study Design. Methodological. Objective. Turkish validity and reliability study of Scoliosis Research Society-30 (SRS-30) questionnaire. Summary of Background Data. SRS-30 is the most current questionnaire of SRS, which is widely used in the evaluation of the treatment of patients with idiopathic scoliosis. There is no validity and reliability study for the Turkish language. Methods. All translation and cross-cultural adaptation stages of the SRS-30 English version to Turkish were implemented. SRS-30 Turkish and Short Form-36 questionnaires were administered to 96 patients with adolescent idiopathic scoliosis simultaneously. Two weeks later, the SRS-30-Turkish version was applied again. Internal validity was examined using the Rasch model, and external construct validity (convergent validity) was evaluated with the Spearman rho correlation test. Person Separation Index was used for reliability. The internal consistency was analyzed with Cronbach alpha. For test re-test reliability, intraclass correlation coefficient between the two measurements was calculated.Results. As a result of the Rasch analysis, it was observed that the Turkish version of SRS-30 has a multidimensional structure and the disordered threshold problem was observed in some items. Overall fit is provided for each of the four sub-dimensions of SRS-30 Turkish. There was no difference in the functioning of the items in terms of gender and age groups. The lowest Person Separation Index value was obtained with 0.539 in the satisfaction of the treatment sub-dimension. Cronbach alpha values were over 0.70 for all domains. The intraclass correlation coefficient value was found in satisfaction with management dimension (0.463) and above 0.60 in other dimensions. Conclusion. It was concluded that the SRS-30 Turkish questionnaire was valid and reliable in evaluating the treatment of patients with adolescent idiopathic scoliosis. Considering the studies related to SRS scales in the literature, especially those applied Rasch analysis, it is seen that the reply categories of the items should be reviewed.

The Validation of the Japanese Version of the Scoliosis Research Society-30 Questionnaire for Adolescent Idiopathic Scoliosis Patients

“…16,17 Several translations and validations of the SRS-30 into languages other than English have been reported. [9][10][11][12][13] The present study aimed to cross-culturally translate and adapt the SRS-30 questionnaire and to evaluate its validity in native Japanese-speaking patients. The results of this study showed that the Japanese SRS-30 questionnaire was successfully developed and adapted, and the Japanese version of the SRS-30 total score had a high internal consistency, with Cronbach α = 0.861 for Japanese-speaking AIS patients.…”

“…However, the Japanese version of the SRS-30 questionnaire has not yet been validated. [9][10][11][12][13] Therefore, this study aimed to validate the Japanese version of the SRS-30 questionnaire for AIS.…”
