  Debasement and faking bad on the Millon Clinical Multi-axial Inventory III: An examination of characteristics, circumstances and motives of forensic patients

  摘要：

  Purpose. This article constitutes the first effort to consider debasement employing the Millon Clinical Multi‐axial Inventory III (MCMI‐III) in a forensic clinical population and incorporating the recommendations of Van Denburg and Choca (1997). It considers the proposition (Rogers, 1990a) that the pathogenic and criminological models of malingering can be rejected in favour of the adaptional model. Methods. A total of 142 MCMI‐III profiles were collected over a 17‐month period by a forensic psychology service. Of these, 47 had Debasement scale scores greater than 74. From the remaining 75, a group of 47 were randomly selected for comparative purposes. Of the total sample there were 75 males and 19 females, 68 were out‐patients and 26 were in‐patients, the latter having been detained under the Mental Health Act 1983, applicable to England and Wales. The two groups were compared on personality variables, offending history, presenting problems and referral circumstances. Results. There is tentative support for Rogers (1990a) in that situational variables appear to have a significant impact on debasement as would be predicted by the adaptional model of malingering. However, this was insufficient evidence to reject the pathogenic and criminological models of malingering. Conclusions. It is suggested that a longitudinal study examining the impact of different stages of the mental health or criminal justice system on debasement, and other validity scales, would illuminate the adaptional model further. Factors that influence the inclination to exaggerate psychopathology and which could be manipulated experimentally are also noted. Some speculation about the possible combined use of Debasement and Histrionic, Narcissistic and Compulsive scales in distinguishing between malingerers is offered.
