RESUMO

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.Level of Evidence: 2.

RESUMO

OBJECTIVES: The aim of our study was to develop a smartphone-aided end vertebra selection method and to investigate its effectiveness in Cobb angle measurement. METHODS: Twenty-nine adolescent idiopathic scoliosis patients' pre-operative posteroanterior scoliosis radiographs were used for end vertebra selection and Cobb angle measurement by standard method and smartphone-aided method. Measurements were performed by 7 examiners. The intraclass correlation coefficient was used to analyze selection and measurement reliability. Summary statistics of variance calculations were used to provide 95% prediction limits for the error in Cobb angle measurements. A paired 2-tailed t test was used to analyze end vertebra selection differences. RESULTS: Mean absolute Cobb angle difference was 3.6° for the manual method and 1.9° for the smartphone-aided method. Both intraobserver and interobserver reliability were found excellent in manual and smartphone set for Cobb angle measurement. Both intraobserver and interobserver reliability were found excellent in manual and smartphone set for end vertebra selection. But reliability values of manual set were lower than smartphone. Two observers selected significantly different end vertebra in their repeated selections for manual method. CONCLUSION: Smartphone-aided method for end vertebra selection and Cobb angle measurement showed excellent reliability. We can expect a reduction in measurement error rates with the widespread use of this method in clinical practice. LEVEL OF EVIDENCE: Level III, Diagnostic study.
