Observational cohort study.
To measure and compare the structural validity of the Oswestry Disability Index (ODI) and the Scoliosis Research Society-30 (SRS-30) questionnaire in an adult population with prolonged degenerative thoracolumbar disease.
The ODI and the SRS-30 are commonly used patient-reported outcome instruments to assess back-specific disability and symptoms related to scoliosis. Still, these instruments have not been validated for degenerative spinal disease with different stages of deformity.
Altogether, 637 consecutive adult patients with degenerative spinal pathologies were included. The patients completed the ODI (version 2.0), the 23 preoperative items of the SRS-30, a general health survey, the Kasari Frequency Intensity Time (FIT) index, the Depression Scale (DEPS), the RAND-36, and visual analog scales for leg and back pain instruments. Psychometric statistical and illustrative analyses were conducted. Deformity groups were analyzed to assess how well the two instruments reflect deformity-related back problems.
Both instruments reflected good coverage and targeting. Correlation between the ODI and the SRS-30 was high (r = 0.70; p < .001). Both measures could distinguish between different general health states. The SRS-30 strongly reflected mental state and social well-being. The SRS-30 was less sensitive for pain and function. Furthermore, the principal component of pain/function explained more variance in the SRS-30 compared with the ODI score. The ODI was more sensitive for variance of disability among different age and deformity groups.
Both the ODI and the the SRS-30 provide valid scores in evaluating health-related quality of life and/or level of disability among patients with prolonged degenerative thoracolumbar disease. The ODI has slightly higher correlation with physical functioning. The SRS-30 seems to be better when evaluating the emotional and psychological functions.
Level III.
观察性队列研究。
测量并比较成人退行性胸腰椎疾病患者中Oswestry功能障碍指数（ODI）和脊柱侧弯研究学会-30（SRS-30）问卷的结构效度。
ODI和SRS-30是常用的患者报告结局工具，用于评估背部特异性功能障碍和与脊柱侧弯相关的症状。然而，这些工具尚未在不同畸形阶段的退行性脊柱疾病中得到验证。
共纳入637例连续性成年退行性脊柱疾病患者。患者完成了ODI（2.0版）、SRS-30的23项术前条目、一项一般健康调查、Kasari频率强度时间（FIT）指数、抑郁量表（DEPS）、RAND-36以及腿部和背部疼痛工具的视觉模拟量表。进行了心理测量统计和说明性分析。对畸形组进行分析，以评估这两种工具反映与畸形相关的背部问题的程度。
两种工具均显示出良好的覆盖范围和针对性。ODI与SRS-30之间的相关性较高（r = 0.70；p <.001）。两种测量方法都能区分不同的一般健康状态。SRS-30强烈反映精神状态和社会幸福感。SRS-30对疼痛和功能的敏感性较低。此外，与ODI评分相比，疼痛/功能的主成分在SRS-30中解释的方差更多。ODI对不同年龄和畸形组之间的功能障碍方差更敏感。
ODI和SRS-30在评估长期退行性胸腰椎疾病患者的健康相关生活质量和/或功能障碍水平方面均提供了有效的评分。ODI与身体功能的相关性略高。在评估情绪和心理功能时，SRS-30似乎更好。
