What is considered one of the most significant risk factors for suicide?

A prior suicide attempt is recognized as one of the most significant risk factors for suicide because it serves as a clear indicator of individuals' previous engagement in suicidal behavior, which greatly increases the likelihood of future attempts. Research has consistently shown that individuals who have previously attempted suicide are at a higher risk of repeating these behaviors due to a variety of factors, including underlying mental health conditions and situational stressors.

Having a past attempt indicates that the individual has experienced profound distress and may still be experiencing unresolved emotional pain. This historical behavior can reflect a range of vulnerabilities, including impulsivity, hopelessness, and a lack of effective coping strategies, which are critical components in understanding suicide risk. Consequently, identifying a prior suicide attempt is a key element of comprehensive risk assessment protocols, such as the C-SSRS, reinforcing the necessity for vigilant monitoring and intervention strategies for these individuals.
