This methodological study aimed to adapt the Neuropathy - and Foot Ulcer - Specific Quality of Life instrument - NeuroQol to Brazilian Portuguese and to analyze its psychometric properties. Participants were 50 people with peripheral diabetic neuropathy and foot ulcers. The floor and ceiling effects, the convergent and discriminant validity and the reliability were analyzed. The Cronbach's alpha coefficient was used to test the reliability and the Pearson's correlation coefficient to estimate the convergent validity, the Student's t test was used to evaluate the discriminant validity in the comparison of the NeuroQol scores between participants with and without ulcers. Floor and ceiling effects were found in some domains of the NeuroQol. The reliability was satisfactory. The correlations between the domains of the NeuroQol and the SF-36 were negative, significant and of moderate to strong magnitude. The findings show that the Brazilian version of the NeuroQol is reliable and valid and may be employed as a useful tool for improving nursing care for people with DM.
这项方法学研究旨在将《神经病变与足部溃疡特异性生活质量量表 - NeuroQol》改编为巴西葡萄牙语，并分析其心理测量特性。研究对象为50名患有外周糖尿病神经病变和足部溃疡的患者。分析了地板效应和天花板效应、收敛效度和区分效度以及信度。使用克朗巴赫α系数检验信度，使用皮尔逊相关系数估计收敛效度，使用学生t检验评估有溃疡和无溃疡参与者之间NeuroQol得分比较中的区分效度。在NeuroQol的某些领域发现了地板效应和天花板效应。信度令人满意。NeuroQol各领域与SF - 36之间的相关性为负，显著且呈中等到强的程度。研究结果表明，巴西版的NeuroQol可靠且有效，可作为改善糖尿病患者护理的有用工具。
