Early screening of physical and psychosocial risk factors has been advocated as a way to identify low back pain (LBP) patients who may develop chronic disability. This study evaluated the predictive validity of a Chinese version of the Orebro Musculoskeletal Pain Questionnaire (OMPQ) in identifying LBP patients at risk of developing poor return-to-work (RTW) outcomes.
Altogether 241 patients with acute or subacute non-specific LBP agreed to participate, and they were screened at baseline with OMPQ, and evaluated after discharge from physiotherapy (n = 173) with outcome measures including the Roland-Morris Disability Questionnaire (RMDQ), numerical pain score (0-10) and global recovery (0-10). At 1-year follow-up, information on RTW status as well as sick leave duration were obtained.
At baseline the OMPQ had a mean score of 112.0 (SD = 26.5). The receiver operator characteristic (ROC) curves of OMPQ scores at 1-year follow-up recorded values of area under the curve of 0.693 for RTW and 0.714 for sick leave duration, which are comparable to those reported in European studies. OMPQ was the only factor that could significantly predict the RTW outcomes, compared to other variables such as the RMDQ scores.
The results confirmed the predictive validity of the Chinese version of OMPQ in screening LBP patients at risk of developing poor occupational outcomes, and appropriate interventions can be arranged for these high-risk individuals in the rehabilitation process.
早期筛查身体和心理社会风险因素已被提倡为识别可能发展为慢性残疾的腰痛（LBP）患者的一种方法。本研究评估了中文版 Orebro 肌肉骨骼疼痛问卷（OMPQ）在识别有发展为不良职业康复结局风险的 LBP 患者方面的预测效度。
共有 241 名急性或亚急性非特异性 LBP 患者同意参与，他们在基线时接受 OMPQ 筛查，并在物理治疗出院后（n = 173）进行评估，使用 Roland-Morris 残疾问卷（RMDQ）、数字疼痛评分（0-10）和整体康复（0-10）等结局指标进行评估。在 1 年随访时，获得了关于重返工作岗位（RTW）状态和病假持续时间的信息。
基线时 OMPQ 的平均得分为 112.0（SD = 26.5）。1 年随访时 OMPQ 得分的受试者工作特征（ROC）曲线记录的曲线下面积值为 0.693 用于 RTW 和 0.714 用于病假持续时间，与欧洲研究报告的值相当。与 RMDQ 评分等其他变量相比，OMPQ 是唯一能够显著预测 RTW 结局的因素。
结果证实了中文版 OMPQ 在筛查有发展为不良职业结局风险的 LBP 患者方面的预测效度，并且可以在康复过程中为这些高风险个体安排适当的干预措施。
