A taxometric analysis of the Psychopathy Checklist–Revised (PCL-R) is conducted on a group of 409 male maximum-, medium-, and minimum-security federal prison inmates using the four PCL-R facet scores (interpersonal, affective, impulsive lifestyle, and antisocial behavior) as indicators. Results obtained from three quasi-independent taxometric procedures—mean above minus below a cut, maximum eigenvalue, and latent mode factor analysis—reveal consistent support for a dimensional interpretation of the psychopathy concept in a moderately heterogeneous sample of participants. On the basis of these results, it is concluded that psychopathy falls along a continuum and that high and low scores on the PCL-R reflect quantitative differences in degree rather than qualitative differences in kind.
