In the evaluation of a patient with a history of a previous suicide attempt, which characteristic of that earlier attempt is the strongest predictor of eventual completed suicide?
- A Use of a highly lethal or violent method ✓
- B Occurrence during adolescence
- C Absence of any diagnosed psychiatric disorder
- D Attempt made in the presence of family members
Correct answer: A. Use of a highly lethal or violent method
Explanation
A previous attempt using a violent or highly lethal method, such as hanging or firearms, is one of the strongest predictors of future completed suicide, reflecting both intent and readiness to die. Psychiatric illness, particularly depression and substance use, increases risk rather than protecting against it, adolescent onset carries lower short-term lethality than later attempts, and an attempt witnessed by family usually allows early rescue and indicates lower isolation.
