The present study aimed to develop an internal validity indicator for a brief general purpose screening battery, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). Two subtests of the RBANS were predicted to be relatively resilient to cognitive dysfunction on the basis of previous research. An Effort Index (EI) was created by combining them via a scaling system. The frequency of EI scores was first examined in a heterogenous clinical sample. A subsequent validation study showed good discriminability. In conclusion, the EI appears to be useful for detecting insufficient effort on a screening battery.
本研究旨在为一种简短通用筛查量表——可重复神经心理状态评估量表（RBANS）开发一种内部效度指标。根据先前研究，RBANS的两个子测验预计对认知功能障碍具有相对较强的抵抗力。通过一个量表系统将它们组合起来创建了一个努力指数（EI）。首先在一个异质性临床样本中检查EI分数的频率。随后的一项验证研究显示出良好的区分能力。总之，EI似乎有助于在筛查量表中检测出努力不足的情况。
