The Minnesota Multiphasic Personality Inventory-2-RF (MMPI-2-RF) validity scales were evaluated to determine accuracy when differentiating honest responding, random responding, genuine posttraumatic stress disorder (PTSD), and feigned PTSD. Undergraduate students (n = 109), screened for PTSD, were randomly assigned to 1 of 4 instructional groups: honest, feign PTSD, half random, and full random. Archival data provided clinical MMPI-2-RF profiles consisting of 31 veterans diagnosed with PTSD. Veterans were diagnosed with PTSD using a structured interview and had passed a structured interview for malingering. Validity scales working as a group had correct classification rates of honest (96.6%), full random (88.9%), genuine PTSD (80.7%), fake PTSD (73.1%), and half random (44.4%). Results were fairly supportive of the scales' ability to discriminate feigning and full random responding from honest responding of normal students as well as veterans with PTSD. However, the RF validity scales do not appear to be as effective in detecting partially random responding.
明尼苏达多相人格测验-2 修订版（MMPI-2-RF）的效度量表被评估，以确定其在区分诚实反应、随机反应、真实创伤后应激障碍（PTSD）和伪装 PTSD 时的准确性。对有 PTSD 筛查的本科生（n=109）进行随机分配，分为 4 个教学组之一：诚实组、伪装 PTSD 组、半随机组和全随机组。档案数据提供了临床 MMPI-2-RF 图谱，其中包括 31 名被诊断患有 PTSD 的退伍军人。退伍军人使用结构化访谈进行 PTSD 诊断，并通过了伪装失能的结构化访谈。作为一个整体的效度量表对诚实（96.6%）、全随机（88.9%）、真实 PTSD（80.7%）、伪装 PTSD（73.1%）和半随机（44.4%）的分类准确率相当高。结果相当支持这些量表能够区分正常学生的伪装和全随机反应与 PTSD 退伍军人的诚实反应。然而，RF 效度量表似乎在检测部分随机反应方面效果不佳。
