A. Within the last 24 months, the individual has made a suicide attempt. (Note: A suicide attempt is a self-initiated sequence of behaviors by an individual who, at the time of initiation, expected that the set of actions would lead to his or her own death. The "time of initiation" is the time when a behavior took place that involved applying the method.)
B. The act does not meet criteria for nonsuicidal self-injury - that is, it does not involve self-injury directed to the surface of the body undertaken to induce relief from a negative feeling/cognitive state or to achieve a positive mood state.
C. The diagnosis is not applied to suicidal ideation or to preparatory acts.
D. The act was not initiated during a state of delirium or confusion.
E. The act was not undertaken solely for a political or religious objective.
- Current: Not more than 12 months since the last attempt.
- In early remission: 12-24 months since the last attempt.
Suicidal behavior is often categorized in terms of violence of the method. Generally, overdoses with legal or illegal substances are considered nonviolent in method, whereas jumping, gunshot wounds, and other methods are considered violent. Another dimension for classification is medical consequences of the behavior, with high-lethality attempts being defined as those requiring medical hospitalization beyond a visit to an emergency department. An additional dimension considered includes the degree of planning versus impulsiveness of the attempt, a characteristic that might have consequences for the medical outcome of a suicide attempt.
If the suicidal behavior occurred 12-24 months prior to evaluation, the condition is considered to be in early remission. Individuals remain at higher risk for further suicide attempts and death in the 24 months after a suicide attempt, and the period 12-24 months after the behavior took place is specified as "early remission."
