The present study investigated whether the conceptualization of hip and knee osteoarthritis pain implicit in the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Medical Outcomes Study Short-Form 36 (SF-36) scales is complete, or whether the addition of another scale, such as the Short-Form McGill Pain Questionnaire (MPQ-SF), provides a more complete characterization. Furthermore, the impact that mental health symptoms and catastrophizing had on these scales was investigated.
Before hip and knee arthroplasty, 200 patients completed surveys of demographic data, the WOMAC pain scale, the MPQ-SF, the SF-36 Bodily Pain scale, the Pain Catastrophizing Scale and the Hospital Anxiety and Depression Scale. Correlations between scales were calculated and linear regression modelling was used to determine the impact of mental health and catastrophizing on these three pain measures.
A strong correlation between the WOMAC and SF-36 pain scales (r=-0.70) was found; however, both correlated only moderately with the MPQ-SF (r=0.36 and r=-0.36, respectively). Linear regression modelling showed that the Pain Catastrophizing Scale significantly predicted a greater score on all three pain scales (P<0.05).
The addition of the MPQ-SF appears to add to a more complete quantification of the pain experience in hip and knee osteoarthritis.
本研究旨在探讨 Western Ontario and McMaster Universities Arthritis Index（WOMAC）和 Medical Outcomes Study Short-Form 36（SF-36）量表中隐含的髋和膝关节骨关节炎疼痛概念是否完整，或者是否需要添加另一个量表，如 Short-Form McGill Pain Questionnaire（MPQ-SF），以提供更完整的特征描述。此外，还研究了心理健康症状和灾难化对这些量表的影响。
在髋关节和膝关节置换术前，200 名患者完成了人口统计学数据、WOMAC 疼痛量表、MPQ-SF、SF-36 身体疼痛量表、疼痛灾难化量表和医院焦虑和抑郁量表的调查。计算了量表之间的相关性，并使用线性回归模型确定心理健康和灾难化对这三个疼痛测量指标的影响。
发现 WOMAC 和 SF-36 疼痛量表之间存在很强的相关性（r=-0.70）；然而，两者与 MPQ-SF 的相关性仅中度相关（r=0.36 和 r=-0.36）。线性回归模型显示，疼痛灾难化量表显著预测了所有三个疼痛量表的更高得分（P<0.05）。
添加 MPQ-SF 似乎可以更全面地量化髋和膝关节骨关节炎的疼痛体验。
