Clinicians and legal practitioners have often assumed uncritically that sensational interests are predictive of sadistic personality disorder (SADPD). This association has never been empirically tested in a non-pathological sample. Using a sample of adults (<i>N</i> = 219) from two countries, a four-factor SADPD structure was identified. A latent variable model was used to test the hypothesis that sensational interests questionnaire (SIQ) scores would be associated with SADPD scores after the separation of general and specific variance. The general association was not significant, but a direct pathway from SIQ Criminal Identity to SADPD Antisocial was required, to improve model fit. SADPD was predicted largely by normal personality traits. Sensational interests are therefore not a simple signifier of deviance or sadism in clinical and legal contexts. However, Criminal Identity may emerge as a risk factor for certain forms of antisocial behaviour, and should be investigated further.
