Evaluating the psychometric and clinical performances of the RM-18, the shorter version of the Roland Morris Disability Questionnaire (RMQ), in Italian people with non-specific low back pain (NSLBP) as a time-saving and clinically useful method of assessing disability.
This cross-sectional study included 74 people (52 females and 22 males, 53.03 ± 15.25 years old) with NSLBP. The RM-18, the RMQ, the Oswestry Disability Index (ODI), and a pain intensity numerical rating scale (NRS) were administered. Psychometric testing included reliability by internal consistency (Cronbach's alpha) and test-retest measurement (Intraclass Correlation Coefficient, ICC2.1), and concurrent validity by comparing the RM-18 with the RMQ and the ODI (Pearson's r correlation). Two separate regression analyses were performed to investigate the different impact of RM-18 and RMQ on NRS.
Cronbach's α of RM-18 was 0.92 and ICC (2,1) = 0.96. Strong correlations were found with the RMQ and the ODI (r = 0.98; r = 0.78, respectively). The regression models showed that the RM-18 and the RMQ similarly impacted the NRS ( < 0.001).
The RM-18 showed satisfactory psychometric testing and similarly impacted the NRS when compared to the RMQ. It can be recommended for clinical and research purposes in Italian people with NSLBP.
评估罗兰·莫里斯残疾问卷（RMQ）的简短版本RM - 18在意大利非特异性下腰痛（NSLBP）患者中的心理测量学和临床性能，作为一种节省时间且对评估残疾具有临床实用性的方法。
这项横断面研究纳入了74例NSLBP患者（52例女性和22例男性，年龄53.03±15.25岁）。采用了RM - 18、RMQ、奥斯威斯功能障碍指数（ODI）和疼痛强度数字评定量表（NRS）。心理测量测试包括通过内部一致性（克朗巴哈α系数）和重测测量（组内相关系数，ICC2.1）评估可靠性，以及通过将RM - 18与RMQ和ODI进行比较（皮尔逊r相关性）评估同时效度。进行了两项独立的回归分析，以研究RM - 18和RMQ对NRS的不同影响。
RM - 18的克朗巴哈α系数为0.92，ICC（2,1）= 0.96。与RMQ和ODI发现强相关性（分别为r = 0.98；r = 0.78）。回归模型显示，RM - 18和RMQ对NRS的影响相似（<0.001）。
RM - 18显示出令人满意的心理测量测试结果，与RMQ相比，对NRS的影响相似。对于意大利NSLBP患者的临床和研究目的，它是值得推荐的。
