It is unclear whether symptom validity test (SVT) failure in neuropsychological and psychiatric domains overlaps. Records of 105 patients referred for neuropsychological evaluation, who completed the Test of Memory Malingering (TOMM), Reliable Digit Span (RDS), and Millon Clinical Multiaxial Inventory-III (MCMI-III), were examined. TOMM and RDS scores were uncorrelated with MCMI-III symptom validity indices and factor analysis revealed two distinct factors for neuropsychological and psychiatric SVTs. Only 3.5% of the sample failed SVTs in both domains, 22.6% solely failed the neuropsychological SVT, and 6.1% solely failed the psychiatric SVT. The results support a dissociation between neuropsychological malingering and exaggeration of psychiatric symptoms in a neuropsychological setting.
在神经心理学和精神科领域,症状效度测试(SVT)失败是否存在重叠尚不清楚。对105名因神经心理学评估而转诊的患者的记录进行了检查,这些患者完成了记忆伪装测试(TOMM)、可靠数字广度测试(RDS)和米隆临床多轴问卷第三版(MCMI-III)。TOMM和RDS得分与MCMI-III症状效度指标不相关,因子分析揭示了神经心理学和精神科SVT的两个不同因子。样本中只有3.5%在两个领域的SVT中均失败,22.6%仅在神经心理学SVT中失败,6.1%仅在精神科SVT中失败。结果支持在神经心理学环境中神经心理学伪装与精神症状夸大之间的分离。
