Statistical analysis calculated reliability, floor effects, ceiling effects ISYQOL. After that, construct validity was measured by analyzing relationship Scoliosis Research Society-22 patient Questionnaire (SRS-22). Results There were no or questionnaire. Cronbach’s alpha coefficient evaluated for Internal consistency 0.75 no-treated group 0.88 brace-treated group. Intraclass correlation coefficients assessed use test-retest method 0.72 0.80 A strong exists measure SRS-22 scores (rho = 0.62; p < 0.01), reflecting high questionnaires. Both showed statistical difference groups ( > 0.05). Conclusions Trans-cultural validation Chinses language reliability
