Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="pme12468-sec-0001" sec-type="section"> <title>Objective</title> <p>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).</p> </sec> <sec id="pme12468-sec-0002" sec-type="section"> <title>Design</title> <p>This is a cross‐sectional study.</p> </sec> <sec id="pme12468-sec-0003" sec-type="section"> <title>Patients and Methods</title> <p>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.</p> </sec> <sec id="pme12468-sec-0004" sec-type="section"> <title>Results</title> <p>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.</p> </sec> <sec id="pme12468-sec-0005" sec-type="section"> <title>Conclusion</title> <p>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.</p> </sec> </abstract>
