研究设计.前瞻性临床验证研究。本研究的目的是将奥斯韦斯特里残疾指数（ODI）2.0版翻译成芬兰语，并在文化上适应和研究其心理测量特性。ODI是最常见的背部残疾问卷之一。它广泛应用于临床工作和医学研究。到目前为止，还没有经过验证的芬兰版本的ODI版本2.0已被认证。ODI 2.0版已被翻译成芬兰语。本研究共招募了115名背痛患者，由初级保健医生转诊到物理医学和康复科门诊。患者回答问卷包，包括芬兰ODI 2.0、视觉疼痛评估的背痛问卷（Million-VAS）、背痛和腿痛的视觉疼痛量表（VAS（背部）、VAS（腿部））、痴呆量表和一个关于其主观健康的问题。两次给药; 2周前和到达诊所时。ODI的重现性为0.90（95%置信区间[CI] = 0.85-0.94），内部一致性为0.86（95% CI = 0.81-0.90）。因子分析表明，ODI由2个因子加载，解释了总方差的51%。在收敛效度检验中，ODI与Million-VAS相关，r = 0.75（95%CI = 0.64-0.84）; VAS（背部）相关，r = 0.48（95%CI = 0.32-0.62）; VAS（腿部）相关，r = 0.41（95%CI = 0.23-0.57）。芬兰ODI版本2.0被证明是一个有效和可靠的工具，显示出与原始英文版本的心理测量特性。因此，它可以用于评估残疾的芬兰语患者背痛的临床和科学目的。
Study Design. Prospective clinical validation study.Objective. The aims of this study were to translate into Finnish and culturally adapt and study the psycho metric properties of the Oswestry Disability Index (ODI) version 2.0.Summary of Background Data. The ODI is one of the most commonly reported back-specific disability questionnaires. It is widely used both in clinical work and in medical studies. To date, no validated Finnish version of the ODI version 2.0 has been reported.Methods. The ODI version 2.0 was translated into the Finnish language. A total of 115 patients with back pain, referred by the primary care physician to the outpatient clinic of the department of physical medicine and rehabilitation, were recruited for this study. The patients answered a questionnaire package that included the Finnish ODI 2.0, Back Pain Questionnaire for Visual Analogue Assessment (Million-VAS), Visual Analogue Scales of back and leg pain (VAS(back), VAS(leg)), the Depressions Scale, and a question on their subjectively perceived health. The package was administered twice; 2 weeks before and at the arrival to the clinic.Results. Reproducibility of the ODI was 0.90 (95% confidence interval [CI] = 0.85-0.94) and the internal consistency was 0.86 (95% CI = 0.81-0.90). Factor analysis showed that the ODI was loaded on 2 factors, which explained 51% of the total variance. In testing convergent validity ODI correlated with Million-VAS, r = 0.75 (95% CI = 0.64-0.84); VAS(back), r = 0.48 (95% CI = 0.32-0.62); and VAS(leg), r = 0.41 (95% CI = 0.23-0.57).Conclusion. The Finnish ODI version 2.0 proved to be a valid and reliable instrument that showed psychometric properties comparable with the original English version. Therefore, it can be used in assessing the disability among Finnish-speaking patients with back pain for both clinical and scientific purposes.
