The WAIS-III Digit Span and Vocabulary subtests were investigated as indicators of feigned cognitive impairment. Participants included 64 undergraduates randomly assigned to control, symptom-coached, or test-coached groups. Six previously researched validity indicators were examined. We hypothesized that symptom-coached participants would perform worse relative to test-coached simulators. Analyses determined both simulator groups performed lower than controls on all indicators except Vocabulary. Symptom-coached participants, however, did not differ from test-coached participants on any indicator. Classification accuracies for these six indicators ranged from 42 to 78%. While the WAIS-III validity indicators hold some promise, they should not be employed as independent measures.
对韦氏成人智力量表第三版（WAIS-III）的数字广度和词汇分测验作为伪装认知障碍指标进行了研究。参与者包括64名本科生，他们被随机分配到对照组、症状引导组或测验引导组。检查了六个先前研究过的效度指标。我们假设，与测验引导的模拟者相比，症状引导的参与者表现会更差。分析确定，除了词汇分测验外，两个模拟者组在所有指标上的表现都低于对照组。然而，症状引导组的参与者在任何指标上与测验引导组的参与者没有差异。这六个指标的分类准确率在42%至78%之间。虽然WAIS-III效度指标有一定前景，但不应将它们用作独立的测量方法。
