The Italian Spine Youth Quality of Life (ISYQOL) questionnaire is used to evaluate health-related quality of life in adolescents with Idiopathic Scoliosis. The study aimed to undertake the process of cultural adaptation of the ISYQOL questionnaire into Simplified Chinese.
Translate from Italian into Simplified Chinese. It involved 138 adolescents whose Cobb angle ranged between 20 and 40 degrees, 50 wearing the brace and 88 not wearing the brace. Statistical analysis calculated the reliability, floor effects, and ceiling effects of the ISYQOL. After that, construct validity was measured by analyzing the ISYQOL relationship Scoliosis Research Society-22 patient Questionnaire (SRS-22).
There were no floor or ceiling effects in the ISYQOL questionnaire. Cronbach's alpha coefficient evaluated for Internal consistency was 0.75 in the no-treated group and 0.88 in the brace-treated group. Intraclass correlation coefficients assessed with the use of the test-retest method were 0.72 in the no-treated group and 0.80 in the brace-treated group. A strong relationship exists between the ISYQOL measure and SRS-22 scores (rho = 0.62; p < 0.01), reflecting the high validity of the questionnaires. Both ISYQOL and SRS-22 scores showed no statistical difference between groups wearing and not wearing the brace (p > 0.05).
Trans-cultural validation in Chinses language showed the reliability and validity of the ISYQOL.
意大利青少年脊柱生活质量（ISYQOL）问卷用于评估特发性脊柱侧弯青少年的健康相关生活质量。本研究旨在将ISYQOL问卷进行文化调适，翻译成简体中文。
从意大利语翻译成简体中文。研究纳入了138名青少年，其Cobb角在20度至40度之间，其中50人佩戴支具，88人未佩戴支具。统计分析计算了ISYQOL的信度、地板效应和天花板效应。之后，通过分析ISYQOL与脊柱侧弯研究学会-22患者问卷（SRS-22）的关系来测量结构效度。
ISYQOL问卷不存在地板效应或天花板效应。未治疗组内部一致性的Cronbach's alpha系数为0.75，支具治疗组为0.88。采用重测法评估的组内相关系数，未治疗组为0.72，支具治疗组为0.80。ISYQOL测量值与SRS-22评分之间存在强相关性（rho = 0.62；p < 0.01），反映了问卷的高效度。佩戴和未佩戴支具的两组之间，ISYQOL和SRS-22评分均无统计学差异（p > 0.05）。
中文的跨文化验证显示了ISYQOL的信度和效度。
