Rater reliability was evaluated for the system most widely used to assess copy and recall of the Rey Complex Figure: the Osterrieth (1944) 18-item scoring system. The study sample consisted of 95 subjects (49 males, 46 females), most of whom were elderly individuals (M = 59.83, SD = 15.21 years) suffering from memory impairment. Four raters rated copy and delayed-recall protocols, and three raters re-rated the protocols after an interval of 3 months. Results revealed excellent inter- and intra-rater reliability coefficients (.85-.97) for total scores. However, reliabilities for the 18 individual items ranged from poor (.14) to excellent (.96). Differences in both reliability and level of subject performance were observed as a function of item and conditions of copy versus recall. It is concluded that the Osterrieth scoring system supports excellent reliability in use with memory-impaired patients using total scores. Nevertheless, individual-item reliability would benefit from enhancement, for example, via amplified delineation of relevant decision criteria.
对用于评估雷氏复杂图形临摹和回忆的最广泛使用的系统——奥斯特里茨（1944年）18项评分系统，评估了评分者信度。研究样本包括95名受试者（49名男性，46名女性），其中大多数是患有记忆障碍的老年人（M = 59.83，SD = 15.21岁）。四名评分者对临摹和延迟回忆记录进行评分，三名评分者在3个月的间隔后对记录进行重新评分。结果显示总分的评分者间和评分者内信度系数极佳（0.85 - 0.97）。然而，18个单项的信度范围从较差（0.14）到极佳（0.96）。观察到信度和受试者表现水平的差异是项目以及临摹与回忆条件的函数。得出的结论是，奥斯特里茨评分系统在对记忆障碍患者使用总分时支持极佳的信度。然而，单项信度将受益于改进，例如，通过更明确地界定相关决策标准。
