The purpose of this study was to translate and cross-culturally adapt the painDETECT questionnaire into the Persian language and assess the clinometric properties of the translated version (P-PDQ).
This is a single-center prospective observational study. After forward and backward translations, consensus was achieved by the expert panel on the pre-final version. Semantic equivalence of this version was assessed and necessary modifications were made accordingly to achieve the final version (P-PDQ). One hundred and fifty chronic pain patients were sub-classified into neuropathic pain (NeP ( = 82)) or non-NeP ( = 68) groups by two pain specialists. P-PDQ was then administered to 50 patients twice with an interval of 5-7 days to assess relative reliability. Chronbach's and intraclass correlation coefficient (ICC) were calculated to evaluate internal consistency and test-retest reliability of the P-PDQ, respectively. Criterion validity was assessed as the correlation of the P-PDQ and the validated Persian version of the self-report Leeds Assessment of Neuropathic Symptoms and Signs (P-sLANSS).
Chronbach's and ICC of the P-PDQ were 0.76 and 0.97, respectively. The P-PDQ scores were significantly correlated with those of P-sLANSS ( = 0.87, < .01). The mean overall score of P-PDQ was significantly higher in the NeP group ( < .01) which reflects discriminant validity. Sensitivity, specificity, positive and negative predicting values and Youden index were 74.70%, 98.51%, 78.04%, 98.48%, and 0.73, respectively at the cutoff value ≤17.
The P-PDQ is a reliable and valid tool to distinguish neuropathic component in chronic pain cases.
本研究旨在将疼痛 DETECT 问卷翻译成波斯语，并评估翻译版本（P-PDQ）的临床计量学特性。
这是一项单中心前瞻性观察研究。经过正向和反向翻译，专家小组对预终版达成共识。评估了该版本的语义等价性，并相应进行了必要的修改，以获得最终版本（P-PDQ）。150 名慢性疼痛患者由两名疼痛专家分为神经病理性疼痛（NeP（=82））或非神经病理性疼痛（=68）组。然后，向 50 名患者两次发放 P-PDQ，间隔 5-7 天，以评估相对可靠性。分别计算 Cronbach's 和组内相关系数（ICC）以评估 P-PDQ 的内部一致性和测试-再测试可靠性。标准有效性评估为 P-PDQ 与经过验证的波斯语版自我报告的神经病症状和体征评估（P-sLANSS）的相关性。
P-PDQ 的 Cronbach's 和 ICC 分别为 0.76 和 0.97。P-PDQ 评分与 P-sLANSS 评分显著相关（=0.87，<.01）。P-PDQ 的总体评分均值在 NeP 组中显著更高（<.01），这反映了判别有效性。在截断值≤17 时，P-PDQ 的灵敏度、特异性、阳性和阴性预测值和 Youden 指数分别为 74.70%、98.51%、78.04%、98.48%和 0.73。
P-PDQ 是一种可靠且有效的工具，可用于区分慢性疼痛病例中的神经病理性成分。
