A Rorschach investigation of sexual homicide.

A sample of incarcerated sexual homicide perpetrators (n = 18) were compared to a sample of non-sexually offending but violent male psychopaths (n = 23) on select Rorschach variables using the Comprehensive System (Exner, 1991). Results suggest that sexual homicide perpetrators are similar to psychopaths in their attachment abnormality, characterological anger, pathological narcissism, moderate and pervasive formal thought disorder, and borderline reality testing. They are distinguished, however, by a more frequent affectional hunger, a tendency to engage in more dysphoric rumination, and abnormal elevations of nonvolitional ideation (obsessional thoughts) due to unmet instinctual need states. They also show a greater interest in others as whole, real, and meaningful objects. Five psychodynamic factors, supported by the empirical findings, are proposed to partially explain the intrapsychic mechanisms involved in an act of sexual homicide.
