In this study we assess the Italian version of the 15-item Myasthenia Gravis Quality-of-Life questionnaire (MG-QOL15).
The validation protocol included the MG-QOL15, the 36-item Short Form (SF-36), the Besta Neurological Institute Rating Scale for Myasthenia Gravis, and the MG-Composite. We used the Cronbach α to test reliability, the Spearman correlation to test short-term test-retest, the Kruskal-Wallis test to assess differences in MG-QOL15 between patients with different disease severity, and the Wilcoxon signed-rank test to assess sensitivity to change.
Seventy-two patients were enrolled in the study. The mean MG-QOL15 score was 15.2 ± 12.2, with α = 0.93 and test-retest correlation = 0.93. Compared with the SF-36, the MG-QOL15 was superior in differentiating patients with different MG types (P = 0.041) and severity (P = 0.004), showed higher sensitivity to change (P = 0.003 for improved and P = 0.024 for worsened patients), and had higher correlations with the MG-Composite (rho = 0.367 vs. -0.213 and -0.154).
The Italian version of the MG-QOL15 is valid, reliable, stable, and sensitive to changes. Muscle Nerve 56: 716-720, 2017.
在本研究中，我们评估了15项重症肌无力生活质量问卷（MG-QOL15）的意大利语版本。
验证方案包括MG-QOL15、36项简短形式健康调查（SF-36）、贝斯塔神经研究所重症肌无力评定量表以及MG综合量表。我们使用Cronbach α系数检验信度，Spearman相关性检验短期重测信度，Kruskal-Wallis检验评估不同疾病严重程度患者之间MG-QOL15的差异，以及Wilcoxon符号秩检验评估对变化的敏感性。
72例患者纳入本研究。MG-QOL15平均得分为15.2±12.2，α系数=0.93，重测相关性=0.93。与SF-36相比，MG-QOL15在区分不同MG类型（P=0.041）和严重程度（P=0.004）的患者方面更具优势，对变化表现出更高的敏感性（改善患者P=0.003，恶化患者P=0.024），并且与MG综合量表具有更高的相关性（rho=0.367，对比-0.213和-0.154）。
MG-QOL15的意大利语版本有效、可靠、稳定且对变化敏感。《肌肉与神经》56: 716 - 720, 2017。
