Comparisons were made between three groups of maximum security inmates thought to possess varying degrees of motivation to either exaggerate or suppress psychiatric symptomatology in their Minnesota Multiphasic Personality Inventory (MMPI) self-report. A group of individuals requesting single-cell placement (the group hypothesized to be motivated to exaggerate symptomatology) were found to score significantly higher on Scale F, the F-K Index, and a number of special MMPI scales (i.e., D-O, Hy-O, Pd-O, Pa-O, Ma-O, Dissimulation Scale, total number of Obvious Items, O:S Ratio) and significantly lower on scales K, Hy-S, Ma-S, and the total number of Subtle items relative to inmates undergoing parole evaluations (denial condition) or entering group therapy (neutral condition). Differences between the parole and group therapy conditions were relatively small, with only D-O, Hy-O, and the Dissimulation Scale producing statistically significant results. These findings tend to support use of the MMPI in assessing a respondent's test-taking attitude, particularly in cases where the subject is attempting to exaggerate psychiatric symptomatology.
对三组戒备森严的囚犯进行了比较，这三组囚犯在明尼苏达多相人格调查表（MMPI）自陈报告中被认为具有不同程度夸大或掩饰精神症状的动机。一组要求单独监禁的人（该组被假设具有夸大症状的动机）被发现在F量表、F-K指数以及一些特殊的MMPI量表（即D-O、Hy-O、Pd-O、Pa-O、Ma-O、掩饰量表、明显项目总数、O:S比率）上得分显著更高，而在K量表、Hy-S、Ma-S以及相对于接受假释评估的囚犯（否认情况）或参加团体治疗的囚犯（中性情况）的细微项目总数上得分显著更低。假释和团体治疗情况之间的差异相对较小，只有D-O、Hy-O和掩饰量表产生了具有统计学意义的结果。这些发现倾向于支持在评估受访者的应试态度时使用MMPI，特别是在受试者试图夸大精神症状的情况下。
