The Revised Short McGill Pain Questionnaire Version-2 (SF-MPQ-2) is a multidimensional outcome measure designed to capture, evaluate and discriminate pain from neuropathic and non-neuropathic sources. A recent systematic review found insufficient psychometric data with respect to musculoskeletal (MSK) health conditions. This study aimed to describe the reproducibility (test-retest reliability and agreement) and internal consistency of the SF-MPQ-2 for use among patients with musculoskeletal shoulder pain.
Eligible patients with shoulder pain from MSK sources completed the SF-MPQ-2: at baseline (n = 195), and a subset did so again after 3-7 days (n = 48), if their response to the Global Rating of Change (GROC) scale remained unchanged. Cronbach alpha (α) and intraclass correlation coefficient (ICC), and their related 95% CI were calculated. Standard error of measurement (SEM), group and individual minimal detectable change (MDC90), and Bland-Altman (BA) plots were used to assess agreement.
Cronbach α ranged from 0.83 to 0.95 suggesting very satisfactory internal consistency across the SF-MPQ-2 domains. Excellent ICC scores were found in support of the total scale (0.95) and continuous subscale (0.92) scores; the remaining subscales displayed good ICC scores (0.78-0.88). Bland-Altman analysis revealed no systematic bias between the test and retest scores (mean difference = 0.13-0.19). While the best agreement coefficients were seen on the total scale (SEM = 0.5; MDC = 1.2 and MDC = 0.3), they were acceptable for the SF-MPQ-2 subscales (SEM: range 0.7-1; MDC: range 1.7-2.3; MDC: range 0.4-0.5).
Good reproducibility supports the SF-MPQ-2 domains for augmented or independent use in MSK-related shoulder pain assessment, with the total scale displaying the best reproducibility coefficients. Additional research on the validity and responsiveness of the SF-MPQ-2 is still required in this population.
修订版简短麦吉尔疼痛问卷第二版（SF-MPQ-2）是一种多维度的结果测量工具，旨在识别、评估和区分神经性和非神经性疼痛来源。最近一项系统评价发现，关于肌肉骨骼（MSK）健康状况的心理测量数据不足。本研究旨在描述SF-MPQ-2在肌肉骨骼性肩部疼痛患者中的可重复性（重测信度和一致性）及内部一致性。
符合条件的肌肉骨骼性肩部疼痛患者完成SF-MPQ-2：在基线时（n = 195），如果他们对整体变化评分（GROC）量表的反应保持不变，则其中一部分患者在3 - 7天后再次完成该问卷（n = 48）。计算Cronbach α系数和组内相关系数（ICC）及其相关的95%置信区间。使用测量标准误（SEM）、组和个体最小可检测变化（MDC90）以及布兰德-奥特曼（BA）图来评估一致性。
Cronbach α系数范围为0.83至0.95，表明SF-MPQ-2各领域的内部一致性非常令人满意。发现总分（0.95）和连续子量表（0.92）得分的ICC分数极佳；其余子量表显示出良好的ICC分数（0.78 - 0.88）。布兰德-奥特曼分析显示，测试和重测分数之间无系统偏差（平均差异 = 0.13 - 0.19）。虽然总分的一致性系数最佳（SEM = 0.5；MDC = 1.2和MDC = 0.3），但对于SF-MPQ-2子量表也是可接受的（SEM：范围0.7 - 1；MDC：范围1.7 - 2.3；MDC：范围0.4 - 0.5）。
良好的可重复性支持SF-MPQ-2各领域在肌肉骨骼相关肩部疼痛评估中加强或独立使用，总分显示出最佳的可重复性系数。在该人群中仍需对SF-MPQ-2的有效性和反应性进行更多研究。
