Prior suicide attempts are the strongest predictor?

• A. Weak predictor
• B. Not predictive
• C. The strongest predictor
• D. Only relevant for certain ages

Answer: (C)

Prior suicide attempts are the strongest predictor of future suicidality because past behavior signals a persistent vulnerability to suicidal crises. When someone has attempted before, it shows they have navigated a moment of intense distress, have access to means, and may continue to experience risk factors such as mental illness, hopelessness, or chronic stress. This elevated risk is especially high in the period shortly after an attempt but remains greater than for those with no history of attempts over the longer term. While other factors like current mood, substance use, or social support contribute to risk, none are as strongly predictive on their own as a prior attempt. Therefore, recognizing a history of attempts as a red flag aligns with the best-supported understanding of suicide risk across ages and conditions.
