简短、可靠和有效的精神病测量对于临床实践和研究以及确定精神分裂症患者未满足的治疗需求都非常有用。本研究检验了修订行为和症状识别量表（BASIS-R）的精神病量表的并发有效性和受试者操作特征。这项研究的对象是从一家大型心理健康诊所随机抽取的 71 名患有精神分裂症的成年人。西洛杉矶退伍军人医疗中心的研究参与者使用 BASIS-R（一种主观的自我报告测量方法）和加州大学洛杉矶分校简明精神病评定量表（BPRS）（一种由训练有素的研究人员实施的临床医生评定测量方法）进行评估。 BASIS-R 的精神病量表与 BPRS 上的精神病项目显示出良好的并发效度。使用 BPRS 作为测量精神病的黄金标准，接收者操作特征表明 BASIS-R 精神病量表的加权和未加权版本都足以识别中度或以上或严重的精神病。两个版本的性能相似。未加权的分数更容易计算，因此我们建议基于未加权的 BASIS-R 的截止分数。我们确定最佳检测中度或重度精神病的截止分数为 0.5，最佳检测严重或极严重精神病的截止分数为 1.0。 BASIS-R 有潜力作为精神分裂症的评估工具和筛查工具。 (c) 2006 Elsevier B.V. 保留所有权利。
Brief, reliable and valid measures of psychosis can be very useful in both clinical practice and research, and for identifying unmet treatment needs in persons with schizophrenia. This study examines the concurrent validity and receiver operating characteristics of the psychosis scale of the Revised Behavior and Symptom Identification Scale (BASIS-R). The study was conducted with 71 adults with schizophrenia who were randomly sampled from a large mental health clinic. Study participants at the West Los Angeles Veterans Healthcare Center were assessed using the BASIS-R, a subjective, self-report measure, and the UCLA Brief Psychiatric Rating Scale (BPRS), a clinician-rated measure administered by highly trained research staff. The psychosis scale of the BASIS-R shows good concurrent validity with the psychosis items on the BPRS. Using the BPRS as the gold standard for measuring psychosis, receiver operating characteristics suggest that both the weighted and unweighted versions of the BASIS-R psychosis scale adequately identify psychosis that is moderate or greater or severe. The performance of the two versions was similar. Unweighted scores are easier to calculate, and we therefore recommend cutoff scores based on the unweighted BASIS-R. We identified a cutoff score of 0.5 to best detect moderate or greater psychosis, and a cutoff score of 1.0 to best detect severe or extremely severe psychosis. The BASIS-R has potential as an assessment tool and screening instrument in schizophrenia. (c) 2006 Elsevier B.V. All rights reserved.
