Cross-cultural adaptation and independent psychometric assessment of the Scales for Outcomes in Parkinson's disease-Cognition (SCOPA-COG), Brazilian version was performed. Parkinson's disease (PD) patients were evaluated by means of the SCOPA-Motor scale, Hoehn and Yahr staging (HY), Clinical Impression of Severity Index-PD (CISI-PD), Parkinson Psychosis Rating Scale, and Hospital Anxiety and Depression Scale. Cognition was evaluated using the Mini-Mental State Examination (MMSE), Short Portable Mental Status Questionnaire (SPMSQ), and SCOPA-COG. The following attributes were explored: acceptability, scaling assumptions, reliability, precision, and construct validity. One hundred fifty-two patients were assessed (mean age, 63.2 years; disease duration, 7.8 years; median HY stage, 3). Mean SCOPA-COG and MMSE were 18.2 and 25.7, respectively. The internal consistency of the SCOPA-COG (Cronbach's alpha = 0.81; item-total correlation, 0.38-0.62) was satisfactory. While the intraclass correlation coefficient value was 0.80, weighted kappa ranged from 0.30 (dice task) to 0.72 (animal fluency task). The standard error of measurement value for the SCOPA-COG was 3.2, whereas the smallest real difference was 8.9. SCOPA-COG total scores significantly decreased as the HY stage increased (Kruskal-Wallis, P < 0.0001). Age, years of education, and PD duration (all, P < 0.001) were observed to have an independent, significant effect on the SCOPA-COG. The SCOPA-COG is a short, reliable, valid instrument that is sensitive to cognitive deficits specific to PD.
对帕金森病认知功能评定量表（SCOPA-COG）巴西版进行了跨文化适应和独立的心理测量评估。通过SCOPA-运动量表、 Hoehn和Yahr分期（HY）、帕金森病严重程度临床印象指数（CISI-PD）、帕金森精神病评定量表以及医院焦虑抑郁量表对帕金森病（PD）患者进行评估。使用简易精神状态检查表（MMSE）、简易便携式精神状态问卷（SPMSQ）和SCOPA-COG对认知功能进行评估。探讨了以下属性：可接受性、量表假设、信度、精密度和结构效度。对152例患者进行了评估（平均年龄63.2岁；病程7.8年；HY分期中位数为3期）。SCOPA-COG和MMSE的平均值分别为18.2和25.7。SCOPA-COG的内部一致性（Cronbach's α = 0.81；项目与总分的相关性为0.38 - 0.62）令人满意。组内相关系数值为0.80，加权kappa值范围为0.30（骰子任务）至0.72（动物流畅性任务）。SCOPA-COG的测量标准误值为3.2，而最小真实差异为8.9。随着HY分期增加，SCOPA-COG总分显著降低（Kruskal-Wallis检验，P < 0.0001）。年龄、受教育年限和PD病程（均P < 0.001）对SCOPA-COG有独立的显著影响。SCOPA-COG是一种简短、可靠、有效的工具，对PD特有的认知缺陷敏感。
