Low back pain is one of the most common complaints affecting many individuals. The McGill Pain Questionnaire is used in various clinical settings to assess different types of pain and one of the most extensively used outcomes measures for pain in the world. The purpose of this study was to translate and validate the original English version of the SF-MPQ-2 into Urdu (SF-MPQ-2-U).
For this study, Mapi Research Trust protocols were followed for the forward and backward translation. Test-retest reliability was used to assess the reliability. Cronbach's alpha and Omega was used to determine internal consistency. Pearson's correlation was used to evaluate convergent validity. Confirmatory factor analysis was also conducted.
The Cronbach's alpha for SF-MPQ-2-U was 0.73 to 0.79, indicating acceptable internal consistency. Omega score for the SF-MPQ-U were 0.918. The ICC varied from 0.799 to 0.878 for domains of SF-MPQ-2-U. The CFA of the SF-MPQ-2-U met model fit indices with GFI and NFI > 0.90. The inter-scale correlation between baseline and re-test data was from 0.63 to 0.71, indicating a positive and strong correlation. The SF-MPQ-2-U and ODI-U had a baseline correlation of 0.547. The correlation of SF-MPQ-2-U & VAS at baseline data was 0.558. Pearson's correlation between subscales was r = 0.253 with p 0.01, which was statistically significant.
The SF-MPQ-2-U is considered to have good convergent validity at inter scale and between two scale levels. Reliability was checked by test-retest reliability, Internal consistency was checked using Cronbach's alpha and Omega that showed good internal consistency for measuring different types of pain in patients with low back pain who speak Urdu. To make the questionnaire more valid and reliable, it is recommended for the researchers to do in-depth research on larger sample size.
腰痛是影响众多人群的最常见病症之一。麦吉尔疼痛问卷在各种临床环境中用于评估不同类型的疼痛，是世界上使用最广泛的疼痛评估指标之一。本研究的目的是将SF-MPQ-2的原始英文版翻译成乌尔都语（SF-MPQ-2-U）并进行验证。
本研究遵循玛匹研究信托协议进行正向和反向翻译。采用重测信度评估信度。使用克朗巴哈α系数和欧米伽系数确定内部一致性。使用皮尔逊相关性评估收敛效度。还进行了验证性因素分析。
SF-MPQ-2-U的克朗巴哈α系数为0.73至0.79，表明内部一致性可接受。SF-MPQ-U的欧米伽系数为0.918。SF-MPQ-2-U各领域的组内相关系数在0.799至0.878之间。SF-MPQ-2-U的验证性因素分析符合模型拟合指数，GFI和NFI＞0.90。基线数据与复测数据之间的量表间相关性在0.63至0.71之间，表明呈正相关且相关性较强。SF-MPQ-2-U与ODI-U的基线相关性为0.547。基线数据时SF-MPQ-2-U与视觉模拟评分法（VAS）的相关性为0.558。各分量表之间的皮尔逊相关性r = 0.253，p＜0.01，具有统计学意义。
SF-MPQ-2-U在量表间和两个量表水平之间被认为具有良好的收敛效度。通过重测信度检查信度，使用克朗巴哈α系数和欧米伽系数检查内部一致性，结果表明其在测量说乌尔都语的腰痛患者不同类型疼痛方面具有良好的内部一致性。为使问卷更有效和可靠，建议研究人员对更大样本量进行深入研究。
