To the editor:
We read the article �Homicide and major mental disorders: a25-year study� by Schanda et al. (1) with interest. We find itlikely that schizophrenia and delusional disorder would lead toserious violence and murder with delusions being the promin-ent driving force. This would agree with the previously citedliterature (2).It was interesting to note that personality disorder was not
investigated in relation to murder. This would be expected aspersonality disorder (psychopathy) is associated with high riskof violence and recidivism. We would like to know why theauthors did not find this given it is such a strong predictor ofrisk (3, 4).

Reply
Dr Malik correctly noted that personality disorder (PD), inparticular antisocial personality disorder (ASPD), is associatedwith a high risk of violence. This is confirmed by a number ofrecent studies also in case of homicide. Characteristically, thesestudies found individuals with ASPD to be at higher riskcompared to individuals with schizophrenia. The comparison ofthe likelihood of homicide in e.g. schizophrenia and PD requiresthe psychiatric examination of an entire sample of homicide
offenders regardless of any legal or diagnostic assignments.That’s what, for example, Eronen et al. in Finland did (1).
However, this was not the design of our study. As the title says,it was explicitly restricted to major mental disorders (MMD).Moreover, as explained in detail in the Method section, weexclusively examined homicide offenders not guilty by reasonof insanity (2, p. 101).Of course, comorbid PD and substance use disorders (SUD)
play a major role also in homicide offenders with MMD (2–4).In our study, we found a statistically significantly higherlikelihood of homicide in schizophrenia with compared toschizophrenia without comorbid alcoholism. Comparable cal-culations for comorbid PD in MMD would have requiredrespective epidemiological basis data. Unfortunately, such datadid not exist until now. But, the rates of comorbid PD in oursample by far exceeded the rates of PD in the generalpopulation (2, p. 103). According to Joyal et al., psychotichomicide offenders with comorbid ASPD represent a subgroupcharacterized by high rates of comorbid alcoholism. Theseoffenders were less likely driven by psychotic symptoms andmore likely attacked strangers compared with psychoticoffenders without comorbid ASPD and SUD (5).So, PD and SUD are strong predictors of homicidal violence
also in psychotic offenders. Therefore, we cannot find anycontradiction between Dr Malik’s notion that PD is associatedwith a high risk of violence in general and our findings. His finalquestion, however, concerning the investigation of the risk ofhomicide in �pure� PD can simply be answered: this was not theaim of our study and would have required a different design.
