The aims of this study were; 1) to develop the final version of the Korean Roland-Morris Disability Questionnaire (RDQ), and 2) to compare the responsiveness between the RDQ and the Oswestry Disability Index (ODI) scores in patients having low back pain. The psychometric properties of the final Korean RDQ were evaluated in 221 patients. Among them, 30 patients were reliability tested. Validity was evaluated using an 11-point numerical rating scale (NRS) and the Korean ODI. The receiver operating characteristic (ROC) curve analysis of the RDQ and the ODI was compared in 54 patients with lumbar zygapophyseal (facet) joint pain. There was a moderate relationship between the RDQ and NRS (r = 0.59, P < 0.01) and a strongly positive correlation between the RDQ and the ODI (r = 0.76, P < 0.001). The Korean RDQ with the higher area under the ROC curve showed a better overall responsive performance than did the ODI in patients with lumbar facet joint pain after medial branch radiofrequency neurotomy (P < 0.01). The results of the study present the final version of the Korean RDQ is valid for assessing functional status in a Korean population with chronic low back pain.
1）制定韩国 Roland-Morris 残疾问卷（RDQ）的最终版本，2）比较 RDQ 和 Oswestry 残疾指数（ODI）在腰痛患者中的反应性。对 221 例患者进行了最终韩国 RDQ 的心理测量学特性评估。其中，30 例患者进行了可靠性测试。使用 11 点数字评分量表（NRS）和韩国 ODI 评估有效性。在 54 例腰椎关节突关节（小面）关节痛患者中比较了 RDQ 和 ODI 的受试者工作特征（ROC）曲线分析。RDQ 与 NRS 之间存在中度关系（r = 0.59，P < 0.01），RDQ 与 ODI 之间存在强正相关（r = 0.76，P < 0.001）。在接受内侧支射频神经切断术治疗后，ROC 曲线下面积较高的韩国 RDQ 在腰椎小面关节痛患者中的整体反应性能优于 ODI（P < 0.01）。研究结果表明，最终版韩国 RDQ 可有效评估韩国慢性腰痛患者的功能状态。
