Understanding the dark side of personality in sex offenders considering the level of sexual violence

This study examined the relationship between the actual level of physical violence in sexual offenses and dark triad, empathic and impulsive personality traits of their perpetrators. Sixty-four male perpetrators of sexual offenses without any serious mental illness were included. A 5-point Likert-type coding system based on Violence Profile for Current Offense was applied to assess the severity of physical violence of each sexual offense. Personality traits of dark triad (psychopathy, Machiavellianism, narcissism), trait empathy and impulsiveness were also evaluated. Multivariate analyses indicated that non-stranger victim, secondary psychopathy, narcissism and empathy could significantly predict greater involvement of physical violence in a sexual offense. In addition, empathy was negatively correlated with all dark triad traits. Sexual violence should be conceptualized in the form of a continuum, and, considering such an approach, offenders with high secondary psychopathy and narcissism may show preference for sexual assaults that are more violent in nature.
