title: Suicidality in the "prodromal" phase of schizophrenia.
abstract: OBJECTIVE
  Patients with schizophrenia are at high risk for suicide ideation, attempts, and completed suicide. However, suicidal behavior during the prodromal phase of schizophrenia and a possible association between prodromal suicidal behavior and suicidality after the onset of overt psychosis are not studied.
  
  
  METHODS
  One hundred six consecutively admitted schizophrenia patients with recent onset were evaluated retrospectively for prodromal symptoms and suicidality during the prodromal phase and after the onset of frank psychosis. In addition, 106 matched control subjects from the general population were evaluated for suicidality during the same age period of the prodromal phase of the corresponding patient.
  
  
  RESULTS
  Suicide ideation and attempt during the prodromal period were reported in 25.5% and 7.5% of the patients, which are 3.8- and 8-fold greater than in the controls, respectively. Patients with suicidal behavior experienced a greater number of prodromal symptoms than those without. Prodromal depressive mood, marked impairment in role functioning, and tobacco smoking exerted an independent effect on suicide ideation, whereas depressive mood was the symptom significantly more frequent in patients with suicide attempt. Suicide attempts were associated with an earlier onset of prodromal symptoms and frank psychosis. All patients with prodromal suicide attempts were cigarette smokers. Suicide ideation during the prodromal phase was strongly associated with lifetime suicidality after the onset of frank psychosis.
  
  
  CONCLUSIONS
  Suicidal behavior is quite common during the prodromal period. The association of smoking, depressive mood, impaired functioning, and a large number of prodromal symptoms, particularly in patients with an early onset of symptomatology, carries a substantially increased risk for suicide ideation. Particular care is needed in patients with prodromal suicide ideation after the onset of frank psychosis because the risk to attempt suicide is high.
