Abstract

Objective: We examined the frequency of possible invalid test scores on the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in patients with schizophrenia spectrum disorders, and whether there was an association between scores on the embedded RBANS performance validity tests (PVTs) and self-reported symptoms of apathy as measured by the Initiate Scale of the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A). Methods: Participants included 250 patients (M = 24.4 years-old, SD = 5.7) with schizophrenia spectrum disorders. Base rates of RBANS Effort Index (EI), Effort Scale (ES), and Performance Validity Index (PVI) test scores were computed. Spearman correlations were used to examine the associations between the RBANS PVTs, the RBANS Index scores, and the BRIEF-A Initiate Scale. Regression analyses were used to investigate how well the RBANS PVTs predicted scores on the BRIEF-A Initiate Scale. Results: The frequency of invalid scores on the EI (>3) and the PVI (<42) in participants with schizophrenia spectrum disorders was 6%. The frequency of invalid ES scores (<12) was 28% in the patients compared to 15% in the U.S. standardization sample. There was a small significant correlation between the EI and the BRIEF-A Initiate Scale (rho=.158, p<.05). Conclusions: The rates of invalid scores were similar to previously published studies. Invalid scores on the BRIEF-A were uncommon. Apathy measured with the BRIEF-A Initiate Scale was not associated with performance on the RBANS validity measures or with measures of cognition.

摘要

目的：我们检查了精神分裂症谱系障碍患者神经心理状态评估可重复电池（RBANS）可能无效测试分数的频率，以及嵌入式 RBANS 性能有效性测试（PVT）的分数与自我报告的冷漠症状，由执行功能行为评定量表的初始量表 - 成人版（BRIEF-A）测量。方法：参与者包括 250 名患者（M  = 24.4 岁，SD = 5.7) 患有精神分裂症谱系障碍。计算了 RBANS 努力指数 (EI)、努力量表 (ES) 和绩效有效性指数 (PVI) 测试分数的基本比率。Spearman 相关性用于检查 RBANS PVT、RBANS 指数分数和 BRIEF-A 启动量表之间的关联。回归分析用于研究 RBANS PVT 在 BRIEF-A Initiate Scale 上预测分数的程度。结果：精神分裂症谱系障碍参与者的 EI（>3）和 PVI（<42）无效分数的频率为 6%。无效 ES 评分 (<12) 的频率在患者中为 28%，而在美国标准化样本中为 15%。EI 和 BRIEF-A Initiate Scale 之间存在微小的显着相关性 ( rho =.158, p<.05). 结论：无效分数的发生率与之前发表的研究相似。BRIEF-A 的无效分数并不常见。用 BRIEF-A Initiate Scale 测量的冷漠与 RBANS 有效性测量或认知测量的表现无关。
