The present study compared the performance of English- and Spanish-speaking healthy controls (HCs) on the Spanish translation of the Dementia Rating Scale-Second edition (ST-DRS-2) and examined the classification accuracy of the ST-DRS-2 and Mini-Mental State Examination (MMSE) with an age- and education-matched clinical sample. In contrast to previous findings with English-speakers, a stronger relationship was observed between ST-DRS-2 Total scores and education than with age, and despite being matched on both of these variables, English-speaking HCs significantly out-performed their Spanish-speaking counterparts on the ST-DRS-2. The greatest between-group difference was found on the Memory subscale, wherein the majority of errors committed by Spanish-speaking HCs were significantly related to level of acculturation. ST-DRS-2 Total and Memory subscale scores produced greater classification accuracy than the MMSE; however, ST-DRS-2 Total scores yielded the greatest corresponding rates of sensitivity and specificity. Normative data are provided and recommended to improve the ST-DRS-2's diagnostic accuracy with Spanish-speakers.
本研究比较了英语和西班牙语母语的健康对照组（HCs）在痴呆评定量表第二版的西班牙语翻译版（ST-DRS-2）上的表现，并通过与年龄和教育相匹配的临床样本，检验了 ST-DRS-2 和简易精神状态检查（MMSE）的分类准确性。与之前对英语使用者的发现相反，ST-DRS-2 总分与教育的相关性强于与年龄的相关性，尽管在这两个变量上相匹配，英语母语的 HCs 在 ST-DRS-2 上的表现明显优于西班牙语母语的 HCs。在记忆分量表上，两组之间的差异最大，西班牙语母语的 HCs 犯的大多数错误都与文化适应水平显著相关。ST-DRS-2 总分和记忆分量表得分比 MMSE 产生了更高的分类准确性；然而，ST-DRS-2 总分产生了最大的相应灵敏度和特异性。提供了并建议使用西班牙语使用者的规范数据来提高 ST-DRS-2 的诊断准确性。
