Retrospective cohort study.
To evaluate the cross-cultural adaptability and internal consistency of the Chinese version of the Quality-of-Life Profile for Spine Deformities (QLPSD) questionnaire in mainland China.
The original QLPSD was translated from Spanish into Chinese with proper cross-cultural adaptation based on the American Academy of Orthopaedic Surgeons guidelines. A total of 129 AIS patients referring to our institution from February 2021 to January 2022 were enrolled in this study. The effects of ceiling and floor were evaluated and the reliability was verified by examining the internal consistency (the Cronbach's α coefficient). Interclass Correlation Coefficient (ICC) was used to test and retest reliability. The C-QLPSD dimensions were compared with the domains in Chinese version of 36-Item Short Form Health Survey (SF-36) and Scoliosis Research Society-22 (SRS-22) questionnaires using Pearson correlation coefficient to assess the concurrent validity.
No significant floor and ceiling effects in C-QLPSD was observed. The total Cronbach's α was estimated at .914, ranging from .768 in back pain dimensions to .862 in psychosocial function dimensions. The C-QLPSD dimensions indicated satisfactory test-retest reliability with ICC range of .784-.870. Construct validity analysis revealed that C-QLPSD was well correlated with SRS-22 and SF-36. The values of total correlation coefficient were calculated at -.924 and -.871, respectively, which were both statistically significant ( < .05).
The adapted Chinese version of QLPSD had good internal consistency and excellent test-retest reliability, which can be used to assess the outcome among Chinese-speaking patients with adolescent idiopathic scoliosis.
回顾性队列研究。
评估中国大陆脊柱畸形生活质量量表（QLPSD）中文版的跨文化适应性和内部一致性。
根据美国矫形外科医师学会指南，将原始的QLPSD从西班牙语翻译成中文，并进行适当的跨文化调适。2021年2月至2022年1月期间转诊至我院的129例青少年特发性脊柱侧弯（AIS）患者纳入本研究。评估天花板效应和地板效应，并通过检验内部一致性（Cronbach's α系数）来验证信度。组内相关系数（ICC）用于测试重测信度。使用Pearson相关系数将C-QLPSD维度与中文版36项简短健康调查问卷（SF-36）和脊柱侧弯研究学会22项问卷（SRS-22）中的领域进行比较，以评估同时效度。
未观察到C-QLPSD有显著的地板效应和天花板效应。Cronbach's α总量估计为0.914，背痛维度为0.768，心理社会功能维度为0.862。C-QLPSD维度显示出令人满意的重测信度，ICC范围为0.784 - 0.870。结构效度分析显示C-QLPSD与SRS-22和SF-36具有良好的相关性。总相关系数值分别计算为-0.924和-0.871，均具有统计学意义（P < 0.05）。
改编后的QLPSD中文版具有良好的内部一致性和出色的重测信度，可用于评估青少年特发性脊柱侧弯的华语患者的预后。
