Background
Emotional dysregulation in schizophrenia results from a pathological transformation of emotions. Rosenzweig frustration test (RFT) is a projective test that discriminates whether an individual reacts with a response of tolerance or intolerance under a frustrating situation. The test comprises 24 pictures that relate to 21 specific categories of assessment of coping strategies in frustration situations. To our knowledge, there is no study on frustration tolerance comparing schizophrenia with or without homicide in the current literature. Our study investigated this area.Materials and Methods
Two groups of patients with schizophrenia were compared. First group consisted of patients with paranoid schizophrenia who had committed homicide 1 to 3 months prior to assessment (n=43, male 35, female 8). Second group included patients with paranoid schizophrenia without homicide (n=40, male 30, female 10). There were no statistically significant differences between groups in terms of age and gender (Table 1).Result
As presented on Figure 1, extra-punitivity is statistically more prominent in the group of patients with schizophrenia and homicide (p<0.05). This is consistent with paranoid ideation of general environmental threat. Other differences without statistical significance are on categories “frustrating situation” and “intropunitivity towards frustrating situation”. So, the situation is more provoking in the group with homicide than one without homicide. Not surprisingly, results for categories “intro-punitivity” and “impunitivity” are higher in the group schizophrenia without homicide, possibly due to better management of violent tendencies.Figure 2 shows that results on “extra-punitivity toward person” are significantly higher in schizophrenia with homicide group than in schizophrenia without homicide group. Higher levels of hostility against others in the group with homicide are one possible explanation. Similar results were found in the item “total blaming of others”, also closely related to hostility. Lower results on categories “intro-punitivity towards person”, “impunitivity towards person”, “self- inculpation”, “collective tendency to self- exculpation” and “collective tendency to exculpation” also might represent that homicidal schizophrenia patients show some specific peculiarities. These results might also be explained as a pathological personality change leading to lower ability to cope with blame. Another possible explanation is premorbid personality traits (Figure 1).
