The Numerical Rating Scale Version of the Pain Disability Quality-Of-Life Questionnaire-Spine (NRS PDQQ-S) is a six question compensate patient reported outcome measure designed for use in the field of minimally invasive interventional spine care. Although acceptable reliability, validity and responsiveness have been confirmed for the Visual Analog Scale version of the PDQQ-S in patients undergoing lumbosacral spine corticosteroid injections and radiofrequency neurotomy, the Numerical Rating Scale version has undergone limited psychometric assessment. The purposes of this study were to define the validity and responsiveness of the NRS PDQQ-S, and to do so in a cohort undergoing an emerging type of spine intervention (platelet rich plasma [PRP] injection). Prospectively gathered pre-and 6months post lumbosacral spine PRP injection(s) NRS PDQQ-S and Oswestry Disability Index (ODI) data were analyzed on 75 patients. NRS PDQQ-S construct validity was evaluated by calculating the correlation with the ODI. Internal responsiveness was estimated for both PDQQ-S and ODI by calculating the effect size (Cohen's ). External responsiveness was estimated by calculating the correlation between the change scores of the NRS PDQQ-S and ODI. Strong statistically significant correlations were documented between the PDQQ-S and ODI questionnaires at pre-PRP injection (r = 0.67; p<.0001) and 6 months post-PRP injection (r = 0.82; p<.0001) supporting construct validity. Internal responsiveness was confirmed by large and comparable effect sizes for both the NRS PDQQ-S [1.1 (CI 0.8-1.4)] (1.1) and ODI [0.9 (CI 0.7-1.2)]. External responsiveness was confirmed by the strong correlation between the change scores of the NRS PDQQ-S and ODI [r = 0.73 (p<.0001)]. This study supports the premise that the NRS PDQQ-S is a valid and responsive instrument that can be used to assess patients with low back pain who are treated with PRP injections.
疼痛残疾生活质量问卷 - 脊柱数字评分量表版本（NRS PDQQ - S）是一份包含六个问题的患者报告结局测量量表，专为微创介入脊柱护理领域设计。虽然已证实PDQQ - S的视觉模拟量表版本在接受腰骶部脊柱皮质类固醇注射和射频神经切断术的患者中具有可接受的信度、效度和反应度，但数字评分量表版本的心理测量评估有限。本研究的目的是确定NRS PDQQ - S的效度和反应度，并在接受一种新型脊柱干预（富血小板血浆[PRP]注射）的队列中进行评估。对75例患者前瞻性收集的腰骶部脊柱PRP注射前后及注射后6个月的NRS PDQQ - S和奥斯维斯特残疾指数（ODI）数据进行了分析。通过计算与ODI的相关性来评估NRS PDQQ - S的结构效度。通过计算效应量（科恩d值）来估计PDQQ - S和ODI的内部反应度。通过计算NRS PDQQ - S和ODI变化分数之间的相关性来估计外部反应度。在PRP注射前（r = 0.67；p <.0001）和注射后6个月（r = 0.82；p <.0001），PDQQ - S和ODI问卷之间记录到了强统计学显著相关性，支持结构效度。NRS PDQQ - S [1.1（CI 0.8 - 1.4）]（1.1）和ODI [0.9（CI 0.7 - 1.2）]的大且可比的效应量证实了内部反应度。NRS PDQQ - S和ODI变化分数之间的强相关性[r = 0.73（p <.0001）]证实了外部反应度。本研究支持以下前提：NRS PDQQ - S是一种有效且有反应度的工具，可用于评估接受PRP注射治疗的腰痛患者。
