To translate, cross-culturally adapt, and validate the Brazilian version of the Parkinson's Disease Sleep Scale-2 (PDSS-2/BR). This cross-sectional study addressed 80 patients with PD, and it was organized into two phases: 1) Translation and cross-cultural adaptation, which included 30 individuals in the scale's pretest stage and 2) Validation, when 50 individuals were assessed by the PDSS-2/BR, Pittsburgh Sleep Quality Index (PSQI), Parkinson's Disease Questionnaire-39 (PDQ-39), MDS-Unified Parkinson's Disease Rating Scale (MDS-UPDRS), and Hoehn and Yahr rating scale (HY); the PDSS-2/BR was retested 7 days later. The significance level was set at 5%. The participants rated the PDSS-2/BR as having more than 90% comprehension. It also showed good reliability (Cronbach's alpha = 0.782) and excellent test-retest reliability (ICC = 0.901; = 0.570; ICC = 0.905; = 0.116). Additionally, the scale showed good precision, with low standard error of measurement (SEM = 1.040; SEM = 0.908), and moderate to strong correlation with the PSQI, MDS-UPDRS, and PDQ-39 scales (rho = 0.46-0.74); only the HY scale showed no correlation. The PDSS-2/BR is a reliable, precise, and valid instrument for evaluating sleep among Brazilian individuals with PD. Hence, it is expected to help researchers and clinicians improve the investigation of these symptoms, promoting early and assertive diagnoses and guiding the treatment and clinical management of this population.
翻译、跨文化调适并验证帕金森病睡眠量表2巴西版（PDSS - 2/BR）。 这项横断面研究涉及80名帕金森病患者，分为两个阶段：1）翻译和跨文化调适，该阶段包括30名处于量表预测试阶段的个体；2）验证阶段，对50名个体进行PDSS - 2/BR、匹兹堡睡眠质量指数（PSQI）、帕金森病问卷39项（PDQ - 39）、MDS统一帕金森病评定量表（MDS - UPDRS）和霍恩和雅尔分级量表（HY）评估；7天后对PDSS - 2/BR进行重测。显著性水平设定为5%。 参与者对PDSS - 2/BR的理解率超过90%。它还显示出良好的信度（克朗巴哈α系数 = 0.782）和出色的重测信度（组内相关系数ICC = 0.901； = 0.570；ICC = 0.905； = 0.116）。此外，该量表显示出良好的精确度，测量标准误差较低（SEM = 1.040；SEM = 0.908），并且与PSQI、MDS - UPDRS和PDQ - 39量表具有中度至高度相关性（相关系数rho = 0.46 - 0.74）；只有HY量表未显示出相关性。 PDSS - 2/BR是评估巴西帕金森病患者睡眠情况的可靠、精确且有效的工具。因此，有望帮助研究人员和临床医生改进对这些症状的调查，促进早期和准确的诊断，并指导该人群的治疗和临床管理。
