The Scale for the Assessment and Rating of Ataxia (SARA) was shown to be a reliable and valid measurement for patients with spinocerebellar ataxia (SCA). The Brazilian version and the Japanese version of SARA were favorable for good reliability and validity. This study aimed to translate SARA into Chinese and test its reliability and validity in measurement of cerebellar ataxia.
SARA was translated into Chinese. A total 39 patients with degeneration cerebellar ataxia were evaluated independently by two neurologists with the Chinese version of SARA. Then the patients were evaluated by one of above neurologists with International Cooperative Ataxia Rating Scale (ICARS). The statistical analyses were performed using SPSS 17.0 for Windows.
The Cronbach's alpha coefficient of the Chinese version of SARA was 0.78, which represents a good internal consistence. The correlation coefficient of the Chinese version of SARA scores between the two evaluators was 0.86, illustrating that the inter-rater reliability of Chinese version of SARA was good. The correlation coefficient between the Chinese version of SARA and ICARS was 0.91, illustrating that the criterion validity of Chinese version of SARA was not bad.
The Chinese version of SARA is reliable and effective for the assessment of degeneration cerebellar ataxia. Compared with ICARS, the evaluation of Chinese version of SARA is more objective, the assessment time is shortened, and the maneuverability is better.
评定与评估共济失调量表（SARA）已被证明是一种用于评估脊髓小脑共济失调（SCA）患者的可靠且有效的测量工具。SARA 的巴西版本和日本版本具有良好的可靠性和有效性。本研究旨在将 SARA 翻译成中文，并测试其在评估小脑共济失调中的可靠性和有效性。
将 SARA 翻译成中文。由两位神经科医生对 39 名变性小脑共济失调患者进行独立评估，使用中文 SARA 进行评估。然后，由上述神经病学家中的一位对患者进行国际合作共济失调评定量表（ICARS）评估。使用 Windows 版 SPSS 17.0 进行统计分析。
中文 SARA 的克朗巴赫 α 系数为 0.78，表明内部一致性良好。两位评估者的中文 SARA 评分之间的相关系数为 0.86，表明中文 SARA 的组内信度良好。中文 SARA 与 ICARS 之间的相关系数为 0.91，表明中文 SARA 的标准效度尚可。
中文 SARA 是评估变性小脑共济失调可靠有效的工具。与 ICARS 相比，中文 SARA 的评估更客观，评估时间更短，操作性更好。
