Abstract
Prior taxometric research on child molesters and general sex offenders has produced inconsistent and contradictory results. There are theoretical, practical, and policy reasons, however, to assume that a psychopathy taxon may exist in sex offenders and that a taxometric study might shed light on this issue. The mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent-mode factor analysis (L-Mode) taxometric procedures were employed in three overlapping samples: 188 sex offenders with non-relative child victims, 555 sex offenders with non-relative child or adolescent victims or child incest victims, and a mixed sample of 1404 sex offenders. The taxometric analyses revealed evidence of continuous latent structure in all three samples. These results suggest that psychopathy in sex offenders, child molesters in particular, is organised quantitatively (continuous) rather than qualitatively (categorical).
