Summary

The ISYQOL questionnaire was translated into Turkish and was assessed the psychometric properties of the Turkish version of the ISYQOL in terms of test-retest reliability, internal consistency, and construct validity in this research.

Detailed description

HRQOL is considered one of the most relevant outcomes of both conservative and surgical treatment of scoliosis, for this reason, several questionnaires (e.g. SRS-24 and SRS-22) have been developed. SRS-22 has been reported as the most commonly used scale to measure HRQOL in patient with scoliosis in many countries. However, current literature showed that SRS-22 has poor measurement properties, it does not satisfy fundamental measure requirements, i.e. additivity, generalizability and unidimensionality. According to Rasch analysis study SRS-24 and SRS-22 presents high ceiling effects in conservative care, for the reason that was developed for surgical candidates. The Italian Spine Youth Quality of Life (ISYQOL) questionnaire originally in Italian, is the first HRQOL questionnaire developed according to the Rasch analysis. It was developed in a conservative treatment setting for all type of spinal deformities, including also patients with surgical curves. The ISYQOL has recently been translated into English, however, its adaptation to the Turkish language is necessary for use in the Turkish population. The psychometric properties of any scale may be affected by translation into another language, that's why it is important for the scale to be evaluated psychometrically. Therefore, the purpose of this study was to translate the ISYQOL questionnaire to Turkish and to assess the psychometric properties of the Turkish version of the ISYQOL in terms of test-retest reliability, internal consistency and construct validity when used on patients with idiopathic scoliosis. Adolescent girls with idiopathic scoliosis who applied to Formed Scoliosis Treatment and Brace Center between September 2018 to 2020 are inviting in this stud by mailing
