To compare the predictive ability of the Orebro Musculoskeletal Pain Questionnaire-a screening tool for psychosocial factors in patients with low back pain across 2 cultural settings (Norway and Australasia) and to establish whether the Orebro provides additional information about outcome than that provided by the baseline value of the prognostic outcome.
Prospective cohort studies with 12 month follow-up; 97 working patients were seeking primary care in Norway and 133 working individuals participated in a trial conducted in Australasia. A series of multiple regression analyses were conducted with pain and disability as outcomes, and the Orebro score and baseline values of the outcome as predictors.
The predictive ability of the Orebro was similar in Norway and Australasia in all the analyses except for disability at 12 months, in which the predictive ability was significantly stronger in Norway as compared to Australasia (P=0.011). The Orebro provided additional information about outcome than that provided by the baseline value of the prognostic outcome: for pain the R-square changes were from 2.4% to 4.0% with no statistically difference between the nationalities. For disability the R-square changes in the Australasian cohort ranged from 1.9% to 4.8% and in the Norwegian cohort from 4.5% to 6.5%.
The Orebro questionnaire had similar predictive ability in Norway and Australasia when pain was used as an outcome, whereas the Orebro tended to be a stronger predictor in Norway when disability was used as outcome.
比较 Orebro 肌肉骨骼疼痛问卷（一种用于评估腰痛患者心理社会因素的筛查工具）在挪威和澳大拉西亚 2 种文化背景下的预测能力，并确定 Orebro 是否能提供比预后结局基线值更多的结局信息。
前瞻性队列研究，随访 12 个月；97 名工作患者在挪威寻求初级保健，133 名工作个体参加了在澳大拉西亚进行的试验。使用疼痛和残疾作为结局，Orebro 评分和预后结局的基线值作为预测因子，进行了一系列多元回归分析。
除了 12 个月时的残疾，Orebro 在挪威和澳大拉西亚的所有分析中的预测能力都相似，而在挪威的预测能力明显强于澳大拉西亚（P=0.011）。Orebro 提供了比预后结局基线值更多的结局信息：对于疼痛，R 平方变化从 2.4%到 4.0%，国籍之间无统计学差异。对于残疾，澳大拉西亚队列的 R 平方变化范围为 1.9%至 4.8%，挪威队列的 R 平方变化范围为 4.5%至 6.5%。
当疼痛作为结局时，Orebro 问卷在挪威和澳大拉西亚的预测能力相似，而当残疾作为结局时，Orebro 在挪威的预测能力更强。
