Suicide is the first cause of premature death in patients with
schizophrenia. Numerous studies have identified risk factors for
suicide among these patients. This study reviews available literature
focusing on awareness of illness in patients with schizophrenia.
Insight, or awareness of illness, has been considered a risk factor for
suicide in schizophrenic patients. In assessing insight, many issues
have to be taken into account, because a high degree of insight is not
desirable in some conditions. (Bulletin of the Menninger Clinic,
68[4], 297-318)
Suicide is the major cause of premature death in patients with schizo-
phrenia. Followup studies have estimated that 10–13% of individuals
with schizophrenia die by suicide (Caldwell & Gottesman, 1990). Most
authors agree that the schizophrenic patient who is more likely to com-
mit suicide is young, male, white, has never married, has good
premorbid function, has postpsychotic depression, and has a history of
substance abuse and suicide attempts. Hopelessness, social isolation,
awareness of illness, and hospitalization are also important risk factors
in schizophrenic individuals who commit suicide. Deteriorating health
with a high level of premorbid functioning, recent loss or rejection, lim-
ited external support, and family stress or instability are other risk fac-
tors traceable in patients with schizophrenia who commit suicide.
These patients usually fear further mental deterioration and experience
excessive treatment dependence or loss of faith in treatment.
Among these risk factors, insight or awareness of illness has received
mixed opinions. Investigators of suicide in schizophrenia generally re-
port that painful insight into one’s own illness may drive a patient to
