What is considered the single best identifier of suicide risk?

Depression is widely recognized as a significant risk factor for suicide and is considered the single best identifier of suicide risk. Individuals diagnosed with depression may experience intense feelings of hopelessness, despair, and emotional pain, which can culminate in thoughts of self-harm or suicide. The prevalence of suicidal ideation is notably higher among those suffering from depression, making it a critical area of focus for risk assessment and intervention.

While other factors like poverty, previous attempts, and substance abuse can contribute to an individual's risk of suicide, they do not hold the same level of direct correlation as depression. Previous attempts are indeed a strong predictor of future attempts, but understanding the underlying mental health condition, specifically depression, is crucial for identifying those at risk. Substance abuse can exacerbate depressive symptoms but is often a secondary factor influenced by the mental health condition. Thus, depression stands out as the primary identifier in assessing suicide risk.
