"When people are suicidal, their thinking is paralyzed, their options appear spare or nonexistent, their mood is despairing, and hopelessness permeates their entire mental domain. The future cannot be separated from the present, and the present is painful beyond solace. ‘This is my last experiment,’ wrote a young chemist in his suicide note. ‘If there is any eternal torment worse than mine I’ll have to be shown."
              — Kay Redfield Jamison (Night Falls Fast: Understanding Suicide)

  • The basic definition of suicide is that it is self-inflicted death with intent to die. However, over the years this definition had morphed and changed based on theories and research. Ultimately, as someone whose life has been touched by suicide, it's most important that we find a definition (or even a combining several definitions) that we feel describes our experience best.
  • Suicide is defined as a death resulting from the use of force against oneself when a preponderance of the evidence indicates that the use of force was intentional.

Suicide Language

The study of suicide, known as suicidology, originated in the 1940s with Edwin Shneidman, Ph.D., and three Los Angeles, California, colleagues: Norman Farberow, Ph.D.; Robert Litman, M.D.; and Mickey Heilig, MSW. The work that these four men began is what almost every piece of the three pillars of the field are built on: prevention, intervention, and postvention.


Prevention is everything that comes before even thoughts of suicide (also known as suicidal ideation). This includes education, to teach people the warning signs to look for and what resources are available if they are worried about someone they care about.


Intervention is what Living Works Education (a suicide prevention training organization based in Canada– calls “suicide first aid or “suicide CPR.” It is identifying someone who is thinking about suicide or who might have a plan to attempt suicide and getting them help.


Postvention, a term coined by Shneidman, is what comes after the attempt or the loss– it is helping the people who are left behind find hope again. And as Shneidman said, postvention after suicide is prevention for the next generation (Shneidman, 1972). By helping the bereaved through their losses, we support their efforts to find life-sustaining hope again.

Self-Injurious Behavior

There are many ways that a person can hurt one’s self. In past years, cutting was seen as one of the more typical methods a person used, however, people burn themselves, bang against walls, and use other ways trying to hurt themselves. These behaviors also were seen as warning signs of suicide although recently are described as ways to cope with pain. However, any sign of a person hurting him or herself always should be taken seriously. Someone using self-injurious behavior to cope with pain is not healthy and needs help learning better coping skills.

Suicidal Ideation

Often called “thoughts of suicide,” suicidal ideation is when someone is thinking about suicide. It doesn’t always mean that someone will attempt to end one’s life but no thoughts of suicide should be ignored; all thoughts of suicide should be taken seriously.

Suicide Survivor

A person who survives a suicide completer; a suicide griever.
