Two studies examined the validity of the Dementia Rating Scale (DRS) as a measure of cognitive functioning among patients with Parkinson's disease (PD). The DRS accounted for more variation in the level of cognitive functioning of PD patients than either the Mini-Mental Status Examination or a battery of tests selected to assess specific cognitive deficits associated with PD. Further, DRS subtests displayed strong convergent and discriminant validity with a comprehensive Criterion Neuropsychology Battery. The DRS subtests appear to be valid measures of attention, perseveration, conceptualization, and memory among PD patients. However, the DRS-Construction subtest should be supplemented with additional visuoconstructional items to provide a thorough screen of cognitive functioning in PD. Although about three-quarters of nondemented PD patients did not appear to have any specific cognitive deficits on the DRS, the remaining patients were impaired on the Construction or Initiation/Perseveration subtests of the DRS. In summary, the DRS is a valid mental status screening test of cognitive functioning for individuals with PD.
两项研究检验了痴呆评定量表（DRS）作为帕金森病（PD）患者认知功能测量工具的有效性。与简易精神状态检查表或一组为评估与PD相关的特定认知缺陷而选择的测试相比，DRS在解释PD患者认知功能水平的差异方面更具优势。此外，DRS子测验与一套全面的标准神经心理学测验显示出很强的聚合效度和区分效度。DRS子测验似乎是评估PD患者注意力、持续性、概念化和记忆力的有效指标。然而，DRS-构图子测验应补充额外的视觉构图项目，以便全面筛查PD患者的认知功能。虽然约四分之三的非痴呆PD患者在DRS上似乎没有任何特定的认知缺陷，但其余患者在DRS的构图或起始/持续性子测验中存在受损情况。总之，DRS是一种用于筛查PD患者认知功能的有效精神状态检查测试。
