ABSTRACT The focus of this report is to compare the psychiatric symptomatology of individuals with schizophrenia who have died by suicide to those who have died by other means of death. This study includes individuals with a diagnosis of schizophrenia whose families donated their brain tissue to the Maryland Brain Collection between September 1989 and August 1998. The psychological autopsy method was used to assess the deceased individual's demographic and clinical characteristics, psychiatric symptoms and history of suicidal thoughts and attempts. Ninety-seven individuals with schizophrenia were identified for this study. Fifteen had committed suicide, while the remaining 82 died from other causes. Thoughts of suicide and previous suicide attempts were more frequent among the group that died from suicide (93% compared to 26%) (p < 0.0001). Suicide victims had a higher rate of depressive symptoms and were twice as likely to have a depressed mood. The incidence of thoughts of dying was 60% compared to 20% in those who did not commit suicide (p = 0.002). Loss of interest was reported to occur in 20% in the suicide group compared to 4% in the group of individuals that died from other causes (p = 0.05). Victims of suicide also had higher rates of positive symptoms throughout their lifetime including thought control, flight of ideas, and loose associations. Suicide is one of the leading cause of premature death in individuals with schizophrenia and identification of risk factors is of great importance. Individuals who die by suicide experience higher rates of depressive symptoms, suicidal thoughts and positive symptoms during their life.

    ABSTRACT: Despite an increased risk for suicide among individuals diagnosed with psychotic disorders, risk factors for completed suicide remain largely unexamined in this population. Using a case-control design, this study aimed to investigate clinical and behavioural risk factors for suicide completion in schizophrenia and other chronic psychotic disorders. A total of 81 psychotic subjects were examined; of these, 45 died by suicide. Proxy-based interviews with, on average, 2 informants were conducted using the SCID I and II interviews and a series of personality trait assessments. Psychotic individuals at risk for suicide are most readily identified by the presence of depressive disorders NOS, moderate to severe psychotic symptoms and a family history of suicidal behaviour. They also exhibited fewer negative symptoms, had more comorbid diagnoses and, contrary to findings in other populations, we found that cluster A and C personality trait symptoms seem to have protective effects against suicide in schizophrenics and other chronic psychotic suicides. Our study suggests that behavioural mediators of suicide risk, such as impulsive-aggressive behaviours, do not play a role in schizophrenic and chronic psychotic suicide. This is contrary to findings in other diagnostic groups, thus implying heterogeneity in predisposing mechanisms involved in suicide.

Yöntem: Çal›flmaya Trabzon Ataköy Ruh ve Sinir Hastal›klar› Hastânesi'nde 2006 y›l›n›n Nisan ve Haziran aylar› aras›nda yatarak tedavi görmekte olan akut dönemdeki 60 flizofrenik hasta ve yine ayn› hastânenin polikliniine bu tarihler aras›nda kontrol için baflvuran stabil dönemdeki 60 flizof- renik hasta olmak üzere toplam 120 hasta al›nm›flt›r. SCID-I'e göre flizofreni tan›s› alan hastalara sosyodemografik veri toplama formu baflta sabit kalmak üzere ayn› s›rayla Beck Umutsuzluk Ölçe- ¤i (BUÖ), Calgary fiizofrenide Depresyon Ölçei (CfiDÖ) ve Pozitif ve Negatif Sendrom Ölçei (PANSS) uygulanm›flt›r. Bulgular: Çal›flmada deneklerin %31,66's›nda intihar düflüncesine, %18,3'ünde ise intihar giriflimi öyküsüne rastlanm›flt›r. Umutsuzluk ve depresyon intihar düflüncesi olan grupta olmayan gruba gö- re anlaml› düzeyde yüksek bulunmufltur. Pozitif belirtiler aç›s›ndan iki grup aras›nda farkl›l›k sap- tanmam›flt›r. ‹ntihar düflüncesi olan grupta negatif belirtiler istatistiksel olarak anlaml› düzeyde yüksek bulunmaktad›r. Tart›flma ve Sonuç: fiizofrenik hastalarda intihar giriflimi öyküsünün, depresyonun ve umutsuzluk düflüncelerinin deerlendirilmesinin flizofrenide intihar davran›fl›n› önlemede önemli olduu düflü- nülmektedir. Negatif belirtilerin intihar davran›fl› ile iliflkisinin ve flizofrenide intihar davran›fl›n›n çok yönlü doas›n›n a盤a ç›kar›lmas›nda yeni çal›flmalara ihtiyaç duyulmaktad›r.

However, little research has been conducted to determine whether the risk for suicidal behavior is elevated among patients with psychosis in general. Being aware of risk factors causing suicidal behavior in schizophrenia can help to develop prevention strategies in this subject. The aim of this study is evaluate the factors on suicide idea at the patients with schizophrenia from the view of some socio-demographic and clinical properties. Method: The sample of the study consists of 120 patients with schizophrenia; from the patients' treated at Trabzon Ataköy Psychiatry Hospital between the dates of April-June 2006; 60 of them in the acute stage taking medical treatment while hospitalized and 60 of them in the stabile stage that applied to the hospital polyclinics for control treatment. Socio-demographic form being in the lead, Beck Hopelessness Scale (BHS), Calgary Depression Scale for Schizophrenia (CDSS) and Positive and Negative Syndromes Scale (PANSS) were applied in the same order were applied to samples being diagnosed as schizophrenia by SCID-I. Findings: In the study 31.66% of the sample has suicidal ideation and 18.3% of the sample has history of suicide attempts. In terms of hopelessness and depression, a significant difference was found out between groups. According to positive symptoms, no difference was present between groups. In the group with suicide ideation, negative symptoms are found out to be significantly higher. Discussion and Conclusion: Evaluating the history of suicide attempts, depression and hopelessness in patients with schizophrenia are thought to be important to prevent suicidal behavi-

    ABSTRACT: Two kinds of investigations can be done about the reasons of the completed suicides: epidemiologic and psycho- logical autopsy. Psychological autopsy is a method that judicial records, psychiatric and other health attainments, information gathered during talking with person's family and other people related, are joined to find out people's personal profiles. The sufficiency of content of sources that will be examined and the reaching people from whom the information will be gotten, are the most important methodical problems in studies of psychological autopsy. The present psychological autopsy studies in Turkey will be examined with psychological autopsy studies in the literature. (Anatolian Journal of Psychiatry 2009; 10:332-335)
