[Risk factors for suicide: a questionnaire survey by psychiatrists in Fukuoka Prefecture].
In our previous study, we demonstrated a preliminary questionnaire survey to psychiatrists from university hospitals, psychiatric hospitals, psychiatric clinics, and departments of psychiatry in general hospitals in Fukuoka Prefecture. In that study, 324 psychiatric patients who committed suicide between January 1, 1998 and December 31, 2001 were ascertained. In the present study, we have recruited matched control patients from the same clinics/hospitals and further demonstrated a secondary questionnaire survey to the psychiatrists in order to reveal the various risk factors for suicide suggested by the literature. Associations between completed suicide and possible risk factors were examined in 192 completed suicide psychiatric patients and 356 non-suicidal psychiatric patients (controls). Significant association was found for history of admission to psychiatric hospitals, history of suicide attempts, history of substance abuse, cluster B personality disorders, and hopelessness in our sample. In male samples, history of suicide attempts, cluster B personality disorders, recent loss, and hopelessness were significantly associated with suicide. In females, history of admission to psychiatric hospitals, history of suicide attempts, and hopelessness were significant.
