Adaptation and validation of the Turkish version of the Quality of Life Profile for Spinal Deformities in idiopathic scoliosis.

The Quality of Life Profile for spinal deformities (QLPSD) was developed to evaluate the quality of life of patients with scoliosis and other spinal deformities. The purpose of the study was to systematically translate the QLPSD into Turkish and examine the reliability and validity of the Turkish version. This methodological study was conducted with 125 participants with idiopathic scoliosis. After the translation of the QLPSD into Turkish systematically, all participants answered the Turkish version of the QLPSD (T-QLPSD) and Scoliosis Research Society-22 items (SRS-22) questionnaires. Intraclass correlation coefficient (ICC) and Cronbach's α statistics were used to test the reliability of the tools: convergent and construct validity of the tools was assessed using exploratory factor analysis and Pearson's correlation analysis. One hundred twenty-five participants were included in the study. The mean age of them was 13.7 ± 2.2 years. For the T-QLPSD total score, Cronbach's α was 0.91, and the ICC was 0.94. A very good correlation was found between T-QLPSD and SRS-22 total scores (r = -0.71). Participants with mild scoliosis reported less back pain (P = .038), better back flexibility (P=.001), and body image (P=.044) compared to moderate scoliosis. The T-QLPSD was found to be a reliable and valid scale for assessing quality of life in idiopathic scoliotic patients in Türkiye.
