Background: Suicide notes provide direct information from suicide victims and often are written shortly before the suicide act. An important question is whether those who write such notes are representative for suicide victims who do not.
Methods: A consecutive series of suicides investigated at the Department of Forensic Medicine in Vienna from April 2002 to March 2003 was examined for the existence of suicide notes. Note writers were compared with non-note writers according to the variables age, sex, family status, occupational status, psychiatric care, suicide motive, and method.
Results and conclusions: Suicide victims who leave suicide notes do not differ statistically significantly from non-note-leavers in sex, age, family status, psychiatric care, motive, or method. This means they are representative for all suicide victims concerning important demographic factors.
