The authors attempted to replicate previous studies that used the Frequency (F) scale and the posttraumatic stress disorder (PTSD) subscale of the MMPI to discriminate Vietnam veterans with PTSD from well-adjusted veterans and mental health professionals who feigned symptoms of PTSD. Profiles of veterans with PTSD were compared to those of veterans with non-PTSD psychiatric disorders and veterans with fabricated PTSD symptoms who sought treatment. Discriminant analysis of F scale and PTSD subscale scores correctly identified only 43.59% of the subjects, thus failing to support use of the MMPI in detecting fabricated symptoms of PTSD in a clinical population.
作者试图重复之前的研究，这些研究使用频率（F）量表和明尼苏达多相人格调查表（MMPI）的创伤后应激障碍（PTSD）分量表，来区分患有PTSD的越南退伍军人与适应良好的退伍军人以及伪装PTSD症状的心理健康专业人员。将患有PTSD的退伍军人的量表剖析图与患有非PTSD精神疾病的退伍军人以及寻求治疗的伪装PTSD症状的退伍军人的剖析图进行比较。对F量表和PTSD分量表得分进行判别分析，仅正确识别出43.59%的受试者，因此不支持在临床人群中使用MMPI来检测伪装的PTSD症状。
