ABSTRACT

This study was designed to examine alternative validity cutoffs on the Boston Naming Test (BNT).

Archival data were collected from 206 adults assessed in a medicolegal setting following a motor vehicle collision. Classification accuracy was evaluated against three criterion PVTs.

The first cutoff to achieve minimum specificity (.87-.88) was T ≤ 35, at .33-.45 sensitivity. T ≤ 33 improved specificity (.92-.93) at .24-.34 sensitivity. BNT validity cutoffs correctly classified 67–85% of the sample. Failing the BNT was unrelated to self-reported emotional distress. Although constrained by its low sensitivity, the BNT remains a useful embedded PVT.

摘要

本研究旨在检查波士顿命名测试 (BNT) 的替代有效性截止值。

档案数据来自 206 名在机动车碰撞后在法医环境中进行评估的成年人。根据三个标准 PVT 评估分类准确性。

达到最低特异性 (.87-.88) 的第一个临界值是 T ≤ 35，灵敏度为 0.33-.45。T ≤ 33 提高了特异性 (.92-.93)，灵敏度为 0.24-.34。BNT 有效性截止值正确分类了 67-85% 的样本。BNT 失败与自我报告的情绪困扰无关。尽管受限于其低灵敏度，BNT 仍然是一种有用的嵌入式 PVT。
