目的认知障碍是精神分裂症的一个重要特征，并与功能预后相关。然而，精神病学缺乏一种能够可靠地评估精神分裂症中常见的认知障碍类型的筛查工具。作者评估了神经心理状态评估（rban）的敏感性、收敛效度和可靠性，以及rban与症状和就业状况的关系。这项新发布的测试需要25分钟才能完成，并在美国人口普查匹配的成年人中进行了标准化。该测试提供总分和5个指标得分，每个指标的平均值为100 （SD = 15）。方法rban数据来自马里兰州精神病学研究中心门诊和住院项目的129例精神分裂症患者。38例患者的RBANS数据与WAIS-III和韦氏记忆量表第3版的表现相关。从53例患者中获得了rban替代形式的可靠性数据；对48例患者进行症状评分；并对77例患者的就业状况进行了调查。结果精神分裂症患者rban功能明显受损（平均总分71.4分）。患者的指数得分表明，他们的语言和视觉功能受损程度相对较小，而记忆力和注意力受损程度相对较小。rban显示出与全面智商和记忆测量的高度相关性。总分具有良好的信度。rban的表现与简短精神病学评定量表的评分相关性极低，但与就业结果密切相关。结论rban似乎是一种有用的精神分裂症认知筛查工具。该仪器可能是一个有用的预后指标，并提供了一种评估认知状态的手段。
OBJECTIVE Cognitive impairment is an important feature of schizophrenia and is correlated with functional outcome. However, psychiatry lacks a screening instrument that can reliably assess the types of cognitive impairment often seen in schizophrenia. The authors assessed the sensitivity, convergent validity, and reliability of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) as well as the relationship of the RBANS to symptoms and employment status. This newly published test takes 25 minutes to administer and was standardized on a U.S.-Census-matched adult population. The test provides a total score and five index scores, each with a mean value of 100 (SD = 15). METHOD RBANS data were obtained from 129 patients with schizophrenia in the outpatient and inpatient programs of the Maryland Psychiatric Research Center. RBANS data were correlated with WAIS-III and Wechsler Memory Scale, 3rd ed. performance in 38 patients. Reliability data for alternate forms of the RBANS were obtained from 53 patients; symptom ratings were obtained from 48 patients; and employment status was examined in 77 patients. RESULTS The patients with schizophrenia demonstrated marked impairment on the RBANS (their mean total score was 71.4). The patients' index scores suggested that they had relatively less impairment of language and visual functions than of memory and attention. The RBANS demonstrated high correlations with full-scale IQ and memory measures. The total score demonstrated good reliability. RBANS performance minimally correlated with Brief Psychiatric Rating Scale ratings but was strongly related to employment outcome. CONCLUSIONS The RBANS appears to be a useful cognitive screening instrument in schizophrenia. The instrument may be a useful prognostic indicator and offers a means of assessing cognitive status.
