研究设计.一项前瞻性临床研究，旨在测试和调整芬兰版脊柱侧凸研究协会30（SRS-30）指南。本研究的目的是进行跨文化适应，并评估适应芬兰版本的SRS-30问卷的有效性。SRS-30问卷已被证明是一个有效的工具，在评估健康相关的生活质量（HRQoL）的青少年和成人脊柱畸形的人口在美国。跨国可用性需要跨文化和语言的适应和验证的工具。使用公认的生活质量问卷翻译方法将SRS-30翻译成芬兰语。共有274例退行性影像学矢状位脊柱疾病的成年患者在2周内回答了问卷调查，包括社会人口学数据、兰德-36、奥斯韦斯特里残疾指数、DEPS抑郁量表和视觉模拟量表（VAS）背痛和腿痛量表。该队列包括既往接受过和未接受过脊柱手术的患者。采用Cronbach α、组内相关、测量标准误、斯皮尔曼相关系数及95%可信区间（CI）检验量表的内部一致性和效度。手术组和非手术组SRS-30的内部一致性良好，Cronbach a分别为0.853（95%CI，0.670 - 0.960）和0.885（95%CI，0.854 - 0.911）。症状稳定患者SRS-30总分域和分项得分域的重测重复性ICC分别为0.905（95%CI，0.870-0.930）和0.904（95%CI，0.871-0.929）。与其他量表相比，该量表在疼痛、自我形象和对管理领域的满意度方面具有区分效度。SRS-30问卷被证明是有效的，适用于评估芬兰成人脊柱畸形患者的HRQoL。它有两个与残疾有关的领域，这两个领域没有被其他普遍使用的问卷所涵盖。
Study Design. A prospective clinical study to test and adapt a Finnish version of the Scoliosis Research Society 30 (SRS-30) questionnaire.Objective. The aim of this study was to perform cross-cultural adaptation and evaluate the validity of the adapted Finnish version of the SRS-30 questionnaire.Summary of Background Data. The SRS-30 questionnaire has proved to be a valid instrument in evaluating health-related quality of life (HRQoL) in adolescent and adult population with spine deformities in the United States. Multinational availability requires cross-cultural and linguistic adaptation and validation of the instrument.Methods. The SRS-30 was translated into Finnish using accepted methods for translation of quality-of-life questionnaires. A total of 274 adult patients with degenerative radiographic sagittal spinal disorder answered the questionnaire with sociodemographic data, RAND-36, Oswestry disability index, DEPS depression scale, and Visual Analog Scale (VAS) back and leg pain scales within 2 weeks' interval. The cohort included patients with and without previous spine surgery. Internal consistency and validity were tested with Cronbach a, intraclass correlation (ICC), standard error of measurement, and Spearman correlation coefficient with 95% confidence intervals (CIs).Results. The internal consistency of SRS-30 was good in both surgery and nonsurgery groups, with Cronbach a 0.853 (95% CI, 0.670 to 0.960) and 0.885 (95% CI, 0.854 to 0.911), respectively. The test-retest reproducibility ICC of the SRS-30 total and subscore domains of patients with stable symptoms was 0.905 (95% CI, 0.870-0.930) and 0.904 (95% CI, 0.871-0.929), respectively. The questionnaire had discriminative validity in the pain, self-image, and satisfaction with management domains compared with other questionnaires.Conclusion. The SRS-30 questionnaire proved to be valid and applicable in evaluating HRQoL in Finnish adult spinal deformity patients. It has two domains related to deformity that are not covered by other generally used questionnaires.
