The objective of this study was to define the validity, reliability, and assessment sensitivity of the Japanese version of the Short-Form McGill Pain Questionnaire 2 (SF-MPQ-2-J).
This is a cross-sectional study.
The original SF-MPQ-2 was translated into Japanese to create the SF-MPQ-2-J, and the cross-cultural equivalence of assessment tool for Japanese patients was validated. The reliability of the SF-MPQ-2-J was assessed using internal consistency, reliability coefficients (Cronbach's α), and reproducibility coefficients (intraclass correlation coefficient) obtained using 234 patients with chronic pain. SF-MPQ-2-J validity was assessed based on associations identified between total and subscale scores compared with other assessment methods. A confirmatory factor analysis (CFA) was also performed to test the theoretical structure of the SF-MPQ-2-J.
The internal consistencies calculated included continuous pain, α=0.893; intermittent pain, α=0.875; predominantly neuropathic pain, α=0.917; affective descriptors, α=0.857; and total score, α=0.907. The reproducibility coefficients calculated included continuous pain, ρ=0.81; intermittent pain, ρ=0.78; predominantly neuropathic pain, ρ=0.85; affective descriptors, ρ=0.75; and total score, ρ=0.83. The CFA showed that the model fit of the readily interpretable subscales was acceptable, and the goodness of fit index value was 0.917. In addition, the mean predominantly neuropathic pain subscale score was found to be significantly higher for patients with neuropathic pain vs non-neuropathic pain.
These findings suggest that the reliability and validity of the SF-MPQ-2-J are excellent, and the SF-MPQ-2-J represents a cross-cultural equivalent to SF-MPQ-2. Consequently, the latter is suitable for research and clinical use, and for discriminating neuropathic pain from non-neuropathic pain.
本研究的目的是确定日语版简化麦吉尔疼痛问卷2（SF-MPQ-2-J）的有效性、可靠性和评估敏感性。
这是一项横断面研究。
将原始的SF-MPQ-2翻译成日语以创建SF-MPQ-2-J，并验证了针对日本患者的评估工具的跨文化等效性。使用内部一致性、可靠性系数（克朗巴哈α系数）以及通过234例慢性疼痛患者获得的再现性系数（组内相关系数）来评估SF-MPQ-2-J的可靠性。基于与其他评估方法相比在总分和分量表得分之间确定的关联来评估SF-MPQ-2-J的有效性。还进行了验证性因素分析（CFA）以检验SF-MPQ-2-J的理论结构。
计算得出的内部一致性包括持续性疼痛，α=0.893；间歇性疼痛，α=0.875；主要为神经性疼痛，α=0.917；情感描述词，α=0.857；以及总分，α=0.907。计算得出的再现性系数包括持续性疼痛，ρ=0.81；间歇性疼痛，ρ=0.78；主要为神经性疼痛，ρ=0.85；情感描述词，ρ=0.75；以及总分，ρ=0.83。CFA表明易于解释的分量表的模型拟合度是可接受的，拟合优度指数值为0.917。此外，发现神经性疼痛患者的主要为神经性疼痛分量表平均得分显著高于非神经性疼痛患者。
这些发现表明SF-MPQ-2-J的可靠性和有效性极佳，并且SF-MPQ-2-J代表了与SF-MPQ-2的跨文化等效物。因此，后者适用于研究和临床应用，以及用于区分神经性疼痛和非神经性疼痛。
