The Relationship between the Psychopathy Checklist–Revised and the MMPI–2: A Pilot Study
The goal of the study was to investigate the relationship between Hare's four-facet model of psychopathy and the Minnesota Multiphasic Personality Inventory-2 (MMPI–2) in a forensic, culturally homogenous sample. 22 male prisoners from Bergen Prison participated. There was only a statistically significant negative zero-order correlation between the total PCL–R score and the score on the Depression scale of the MMPI–2. However, the results revealed that the four facets had different underlying correlates with negative affectivity. Overall, Facets 1 and 2 showed a tendency toward a negative relationship with the clinical scales on the MMPI–2, while Facets 3 and 4 had a positive relationship. Interestingly, partial correlations showed that Facet 4 of PCL–R was the only facet that correlated statistically significantly with the scores on the Psychopathic Deviate scale of the MMPI–2.
