AbstractThis study investigated the interrelationship between alexithymia, defense style, emotional suppression, posttraumatic stress disorder (PTSD) following homicide and psychiatric co-morbidity. One hundred and fifty male homicide perpetrators and 156 male perpetrators of non-violent crime completed the Post traumatic Stress Diagnostic Scale (except for non-violent perpetrators), the General Health Questionnaire -28, the Defense Styles Questionnaire, the Courtauld Emotional Control Scale and the Toronto Alexithymia Scale-20. The results showed that 44% of homicide perpetrators met the criteria for PTSD. No significant differences were found between groups in alexithymia, defense style and psychiatric co-morbidity. Homicide perpetrators suppressed depression significantly more than the non-violent group. PLS analyses showed that alexithymia was significantly correlated with defense style. Defense styles were significantly correlated with emotional suppression which, in turn, was associated with homicide related PTSD and psychiatric co-morbidity. To conclude, perpetrators can experience PTSD reactions following the act of homicide. The severity of these reactions and other psychological problems were related to difficulty getting in touch with distressing emotions, the defenses they used to protect themselves psychologically and the way they suppressed their emotion.
