| Abstract: | BackgroundThe aim of this study was to evaluate the reliability and validity of an adapted Turkish version of the Scoliosis Japanese Questionnaire- 27 (SJ- 27).MethodsTranslation and retranslation of the English version of the SJ- 27 was conducted, and all steps of the cross-cultural adaptation process were performed. The Turkish version of the SJ- 27, the Scoliosis Research Society-22 (SRS- 22) questionnaire and the Short Form-36 (SF- 36) were performed to 139 patients with AIS. Reliability was assessed using the test–retest method (Pearson's correlation coefficient); internal consistency was analyzed using Cronbach's alpha. Validity was assessed by correlating the SJ- 27 with the SRS- 22 questionnaire and SF- 36.ResultsThe mean Cobb angles were 23.2 ± 8.3° and 19 ± 5.9° for thoracic and lumbar regions, respectively. The SJ- 27 showed excellent test/retest reliability with an Intraclass correlation coefficient of 0.99. Internal consistency of the SJ- 27 was found to be very good (Cronbach's alpha = 0.991). The SJ- 27 demonstrated very good construct validity with the SRS- 22 total score (r = 0.61). The similar domains of the SJ- 27 and SF- 36 questionnaire was correlated also in the study.ConclusionsThe Turkish version of the SJ- 27 to measure health related quality of life in adolescent idiopathic scoliosis was found to have very good validity, excellent reliability, and high internal consistency. |
