| Abstract: | Current categorical classification systems of personality disorders (PDs) remain widely used amid growing evidence that argues against the conceptualisation of PDs as independent, discrete entities. Adopting the dimensional perspective of Morey et al. (Journal of Personality Assessment, 49, 245–251, 1985), this study compared PD traits across forensic, psychiatric and “normal” senior business manager samples. There was particular interest in the relative representations of elements of PD closely associated with psychopathic PD because of research suggesting that some “psychopaths” operate within mainstream society, and links that have been made between elements of these so-called “successful” psychopaths, and characteristics associated with success in senior business management roles. The dimensional Minnesota Multiphasic Personality Inventory Scales for DSM III Personality Disorders (MMPI-PD) were shown to be internally consistent for the “normal” sample. Evidence for the qualitative equivalence of the four PD profiles emerged. The PD profile of the senior business manager sample was found to contain significant elements of PD, particularly those that have been referred to as the “emotional components” of psychopathic PD. The findings provide strong support for the continuous distribution of personality disordered traits. |
