The aim of this study is to identify the criteria which would allow a differentiation between the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) profiles, obtained from patients who present with problems of minimization of attitude (dissembling) who have shown a minimization of their problems; from patients who answered in a spontaneous and genuine fashion.
Six hundred and fifty five MMPI profiles of outpatients of the Clinical Psychology Unit, University Hospital, Sapienza University of Rome. Patients were subdivided into two groups, based on the reason for attending: those who submitted voluntarily to a psychodiagnostic assessment and those who were assessed by request of an outside authority, e.g., in the case of those whose driving license was suspended. It has hypothesized that the latter group would not present with problems which would preclude obtaining the benefits required. The variables analyzed were the clinical scale and the validity scale MMPI-2, index F-K and the Ds scale of Gough. On the basis of the values of the F-K index and Ds scale, the patients were reclassified into three simulation categories: spontaneous registration; defended and doubtful's.
All indexes, validity scales and clinical scales of the standard profile were found to have significant differences between the "dissimulation" and "normal" groups. Sensibility and specificity of profile classification was according to both indexes 76%.
Current evidence indicates that simulation of pathology is identifiable in MMPI-2 profiles. Our data demonstrate that it is possible to identify case of defensive minimization. These results confirm the hypothesis that simulation is a dimensional characteristic of MMPI which can reach extreme values in both ways: worsening of slight problems or suppression of existing problems.
本研究的目的是确定一些标准，以便区分从那些表现出态度最小化（掩饰）问题且已将自身问题最小化的患者那里获得的明尼苏达多相人格调查表第二版（MMPI-2）剖面图，与那些以自发且真实方式作答的患者的剖面图。
罗马第一大学医院临床心理科门诊患者的655份MMPI剖面图。患者根据就诊原因分为两组：自愿接受心理诊断评估的患者和应外部机构要求接受评估的患者，例如那些驾照被吊销的患者。假设后一组不会出现妨碍获得所需益处的问题。分析的变量是MMPI-2的临床量表和效度量表、F-K指数以及高夫的Ds量表。根据F-K指数和Ds量表的值，将患者重新分类为三个模拟类别：自发登记；防御性和可疑性。
发现标准剖面图的所有指数、效度量表和临床量表在“掩饰”组和“正常”组之间存在显著差异。剖面图分类的敏感性和特异性根据这两个指数均为76%。
目前的证据表明，在MMPI-2剖面图中可以识别出病理模拟情况。我们的数据表明，可以识别出防御性最小化的病例。这些结果证实了这样的假设，即模拟是MMPI的一个维度特征，它可以通过两种方式达到极端值：轻微问题的恶化或现有问题的抑制。
