Sadism in sexual offenders: evidence for dimensionality.
Recurrent and intense sexual fantasies and urges that circle around the infliction of pain or humiliation on another human being may predispose individuals toward acts of sexual aggression against nonconsenting victims. Consequently, sexual sadism is a paraphilia with particular relevance for forensic psychology and psychiatry. Using behavioral indicators derived from crime scene actions as well as clinical data, we sought in the present study to identify the latent structure of the disorder. We analyzed data from a national sample of male sexual offenders from Austria (N = 1,020). In addition to latent profile analysis, 3 conceptually different taxometric methods were applied. The results of the analyses were more in accordance with a dimensional interpretation than with a categorical distinction. That is, sadistic conduct in sexual offenses is likely an extreme form of coercion, but not a qualitatively different entity. The implications with respect to the current debate on the diagnostic criteria for sadism are discussed.
