Individuals with pain from sickle cell disease (SCD) are often treated for nociceptive pain, but recent findings indicate they may also have neuropathic pain. PAINIt, a computerized version of the McGill Pain Questionnaire, provides a potential subscale that is the summed number of selected neuropathic pain quality words (PR-NNP), but it lacks construct validity. The study purpose was to ascertain PR-NNP construct validity in adults with SCD and chronic pain. In an outpatient setting, 186 participants completed the PAINIt, Neuropathic Pain Symptom Inventory (NPSI), and Leeds Assessment for Neuropathic Symptoms and Signs (S-LANSS). PR-NNP was moderately correlated with NPSI ( = .33, < .001) and S-LANSS ( = .40, < .001). Regression analysis indicated that PR-NNP and pain intensity, but not a nociceptive pain subscale, were significant predictors of NPSI and S-LANSS. Findings support construct validity of PR-NNP, which may be useful as a screening tool for neuropathic pain in patients with SCD.
患有镰状细胞病 (SCD) 的疼痛个体通常接受伤害感受性疼痛治疗,但最近的研究结果表明,他们也可能患有神经病理性疼痛。PAINIt 是麦吉尔疼痛问卷的计算机化版本,提供了一个潜在的分量表,即所选神经病理性疼痛质量词的总和(PR-NNP),但缺乏结构效度。该研究旨在确定 SCD 合并慢性疼痛患者的 PR-NNP 结构效度。在门诊环境中,186 名参与者完成了 PAINIt、神经病理性疼痛症状量表 (NPSI) 和 Leeds 评估神经病理性症状和体征 (S-LANSS)。PR-NNP 与 NPSI(r =.33,<.001)和 S-LANSS(r =.40,<.001)中度相关。回归分析表明,PR-NNP 和疼痛强度,但不是伤害感受性疼痛分量表,是 NPSI 和 S-LANSS 的显著预测因子。研究结果支持 PR-NNP 的结构效度,它可能是 SCD 患者神经病理性疼痛筛查工具的有用工具。
