目的：用于神经心理状态评估的可重复成套测验（RBANS）被设计为认知筛查测试，提供总量表评分和五个特定认知能力指数评分。本研究探讨了重测稳定性的RBANS在个别精神分裂症患者相对于一个健康的comparationgroup.Method：共181例精神分裂症或情感障碍患者被招募从三个临床设置。招募健康对照受试者作为RBANS标准化的一部分。参与者被管理的一种形式的RBANS在一个场合和另一种形式在稍后的日期，间隔范围从1到134 days.Results：组内相关系数为RBANS总规模为0.84为精神分裂症患者和0.77为健康对照组。置信区间和百分位数数据的总规模变化scores.Conclusions：RBANS表现出合理的组内相关系数重测信度对接）精神分裂症患者和健康对照组。置信区间与之前公布的WAIS-R和韦氏记忆量表修订版的置信区间相当，这表明尽管测试很简短，但RBANS的重测测量误差并没有显著增加。这些数据可以作为使用RBANS评估个体水平上的神经心理变化的信息指南。
Objective: The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was designed as a cognitive screening test, providing both a total scale score and five specific cognitive ability index scores. This study examined the test-retest stability of the RBANS in individual patients with schizophrenia relative to a healthy comparison group.Method: A total of 181 patients with schizophrenia or schizoaffective disorder were recruited from three clinical settings. Healthy comparison subjects were recruited as part of the RBANS standardization. Participants were administered one form of the RBANS on one occasion and another form at a later date, with intervals ranging from 1 to 134 days.Results: Intraclass correlation coefficients for the RBANS total scale were 0.84 for the patients with schizophrenia and 0.77 for the healthy comparison subjects. Confidence intervals and percentile data for the total scale change scores were similar for both groups.Conclusions: The RBANS demonstrated reasonable intraclass correlation coefficient test-retest reliability for butt) schizophrenia patients and healthy comparison subjects. Confidence intervals are comparable to those previously published for the WAIS-R and Wechsler Memory Scale-Revised, suggesting that retest measurement error is not dramatically increased in the RBANS, despite the brevity of the test. These data may serve as an informative guide for using the RBANS to evaluate neuropsychological change on the level of the individual subject.
