Rivermead知觉评估组（RPAB）旨在评估中风和头部损伤患者的视觉知觉缺陷。它是专门为职业治疗师开发的为数不多的标准化知觉评估之一。本文研究了RPAB统计背景的一些方面。RPAB作者报告了有限的统计数据，不足以充分理解该评估工具的临床用途。信度和效度进行了检验，并讨论了测试结果的含义。计算每个子测试中患者的真实得分范围，以及临床医生能够确信这种变化代表患者能力的真正改善或下降之前所需的随时间变化的量。此外，每个子测试的判别能力被检查，作为确定知觉缺陷的存在和类型的标准。这些统计分析是基于测试手册中报告的数据，以及来自悉尼亨利王子医院2年来评估的患者的数据。
The Rivermead Perceptual Assessment Battery (RPAB) is designed to assess visual perception deficits in people suffering from stroke and head Injury. It Is one of the few standardised perceptual assessments specifically developed for occupational therapists. This article examines some aspects of the statistical background of the RPAB. The RPAB authors have reported limited statistical data, which Is Insufficient to understand fully the clinical usefulness of this assessment tool. Reliability and validity are examined and the implications of test results are discussed. The true score range for patients on each subtest is calculated, as well as the amount of change over time required before clinicians can be confident that such change represents a real improvement or decline In the patient's ability. Further, the discriminative power of each subtest is examined, as are the criteria for determining the presence and type of perceptual deficit. These statistical analyses were based on the data reported in the test's manual, as well as from patients assessed at The Prince Henry Hospital, Sydney, over a 2-year period.
