Abstract

Objectives:To evaluate the relation between positive and negative symptoms in schizophrenic patients with history and risk of suicidal attempt.Method:This case-control study was carried on 65 Schizophrenic in-patients during the years 2006-2007 and 65 major depressive disorder patients as control group. Both of these groups were evaluated and compared on base of clinical assessments and California diagnostic tests and PANSS (positive and negative syndrome scale).Results:There was significant relationship between positive symptoms in schizophrenic patient and both the California number test (r=0/708,p<0/0001) and history of suicidal attempt (r= 0/558, p<0/0001) .Also thtere was significant and reverse relationship between negative symptoms and both the California number test (P<0/0001, r= -0/529) and history of suicidal attempt (P<0/0001,r=-0/512.). That means rising negative symptoms decrease the risk and history of suicidal attempt.Conclusion:Regarding the results of this survey, schizophrenic patients with positive symptoms such as paranoid schizophrenia have more insight to their illness and probability of depression and increased risk of suicide .Schizophrenic patients with negative symptoms such as deficit Schizophrenia, have less insight to their illness and low probability of depression and risk of suicide.
