研究1检验了从帕金森病运动损伤测试中得出的五个体征和症状项目的评分的可靠性。不同严重程度的帕金森病患者进行了步态、从椅子上站起来和手功能项目的测试。这些表演的录像由大量有经验和没有经验的神经学家和心理学本科生进行评分，采用四分制。量表间信度中等高，步态项目的信度高于手功能项目。临床经验证明对评分及其可靠性没有系统影响。特定表演的特质是不可靠评级的主要来源。研究2检验了由体征和症状项目以及日常生活活动组成的几个标准评定量表的相互关系。量表之间的相关性很高，范围从0.70到0.83，尽管在项目组成上有相当大的差异。项目间相关分析表明，各测试的内部凝聚力较高，尤其是自我照顾量表。回归分析表明，量表之间的关系可以通过少量的测试项目来有效地捕获，从而允许构建一个更简短的测试。
Study 1 examined the reliability of the ratings assigned to the performance of five sign-and-symptom items drawn from tests of motor impairment in Parkinson's disease. Patients with Parkinson's disease of varying severity performed gait, rising from chair, and hand function items. Video recordings of these performances were rated by a large sample of experienced and inexperienced neurologists and by psychology undergraduates, using a four point scale. Inter-rater reliability was moderately high, being higher for gait than hand function items. Clinical experience proved to have no systematic effect on ratings or their reliability. The idiosyncracy of particular performances was a major source of unreliable ratings. Study 2 examined the intercorrelation of several standard rating scales, comprised of sign-and-symptom items as well as activities of daily living. The correlation between scales was high, ranging from 0.70 to 0.83, despite considerable differences in item composition. Inter-item correlations showed that the internal cohesion of the tests was high, especially for the self-care scale. Regression analysis showed that the relationship between the scales could be efficiently captured by a small selection of test items, allowing the construction of a much briefer test.
