The aim of this study was to evaluate the validity and reliability of the Japanese version of the painDETECT questionnaire (PDQ-J).
The translation of the original PDQ into Japanese was achieved according to the published guidelines. Subsequently, a multicenter observational study was performed to evaluate the validity and reliability of PDQ-J, including 113 Japanese patients suffering from pain.
Factor analysis revealed that the main component of PDQ-J comprises two determinative factors, which account for 62% of the variance observed. Moreover, PDQ-J revealed statistically significant correlation with the intensity of pain (Numerical Rating Scale), Physical Component Score, and Mental Component Score of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The Cronbach alpha for the total score was 0.78 and for the main component was 0.80. In the analysis of test-retest method, the intraclass correlation coefficient between the two scores was 0.94.
We demonstrated the validity and reliability of PDQ-J. We encourage researchers and clinicians to use this tool for the assessment of patients who suffer suspected neuropathic pain.
本研究旨在评估疼痛 DETECT 问卷（PDQ-J）的日语版的有效性和可靠性。
根据已发表的指南，将原始 PDQ 翻译成日语。随后，进行了一项多中心观察性研究，以评估 PDQ-J 的有效性和可靠性，共纳入 113 名患有疼痛的日本患者。
因子分析显示，PDQ-J 的主要成分包括两个决定性因素，占观察到的方差的 62%。此外，PDQ-J 与疼痛强度（数字评分量表）、医疗结局研究 36 项简明健康调查（SF-36）的生理成分评分和心理成分评分呈显著统计学相关。总分的 Cronbach α 为 0.78，主要成分的 Cronbach α 为 0.80。在测试-再测试方法的分析中，两个分数之间的组内相关系数为 0.94。
我们证明了 PDQ-J 的有效性和可靠性。我们鼓励研究人员和临床医生使用该工具评估疑似患有神经性疼痛的患者。
