The Michigan Neuropathy Screening Instrument is an easy-to-use questionnaire aimed at screening and detecting diabetic polyneuropathy.
To translate and cross-culturally adapt the MNSI to Brazilian Portuguese and evaluate its measurement properties.
Two bilingual translators translated from English into Brazilian Portuguese and made a synthetic version. The synthetic version was back translated into English. A committee of specialists and the translator checked the cultural adaptations and developed a pre-final questionnaire in Brazilian Portuguese (prefinal version). In pretesting, the prefinal version was applied to a sample of 34 subjects in which each subject was interviewed to determine whether they understood each item. For the later assessment of measurement properties, 84 subjects were assessed.
A final Brazilian Portuguese version of the instrument was produced after obtaining 80% agreement (SEM<0.01%) among diabetic patients and specialists. We obtained excellent intra-rater reliability (ICC=0.90), inter-rater reliability (ICC=0.90) and within-subject reliability ICC=0.80, excellent internal consistency (Cronbach's alpha>0.92), reasonable construct validity for the association between the MNSI and Neuropathy Symptom Score (r=0.46, p<0.05) and excellent association between the MNSI and Neuropathy Disability Score (r=0.79, p<0.05). We did not detect floor and ceiling effects (<9.5% of patients with maximum scores).
The Brazilian Portuguese version of the MNSI is suitable for application in the Brazilian diabetic population and is a reliable tool for the screening and detection of DPN. The MNSI can be used both in clinical practice and also for research purposes.
密歇根神经病变筛查工具（Michigan Neuropathy Screening Instrument，MNSI）是一种简单易用的问卷，旨在筛查和检测糖尿病周围神经病变（diabetic polyneuropathy，DPN）。
将 MNSI 翻译并跨文化适应为巴西葡萄牙语，并评估其测量特性。
两名双语翻译将其从英语翻译成葡萄牙语，并制作出综合版本。综合版本被回译为英语。一个专家委员会和翻译人员检查文化适应性，并开发出一个巴西葡萄牙语的预终版问卷（prefinal version）。在预测试中，将预终版问卷应用于 34 名受试者的样本中，每个受试者都接受了访谈，以确定他们是否理解每个项目。对于后来的测量特性评估，评估了 84 名受试者。
在获得糖尿病患者和专家之间 80%的一致性（SEM<0.01%）后，得出了 MNSI 的最终巴西葡萄牙语版本。我们获得了极好的内部一致性（ICC=0.90）、组内信度（ICC=0.80）、极好的重测信度（ICC=0.90），极好的内部一致性（Cronbach's alpha>0.92），MNSI 与神经病变症状评分（r=0.46，p<0.05）之间具有合理的结构有效性，与神经病变残疾评分（r=0.79，p<0.05）之间具有极好的相关性。我们没有检测到地板和天花板效应（最大得分的患者中<9.5%）。
MNSI 的巴西葡萄牙语版本适用于巴西糖尿病患者群体，是筛查和检测 DPN 的可靠工具。MNSI 可用于临床实践和研究目的。
