When assessing for suicide risk, which factor is considered the biggest risk factor?

In the context of assessing suicide risk, the history of violent behavior is considered a significant risk factor due to its association with impulsivity and aggression. Individuals with a history of violent behavior may have an increased likelihood of engaging in self-directed violence or suicide, as their behavioral patterns indicate a propensity for extreme emotional responses and heightened risk-taking. This past behavior may reflect underlying mental health issues and present a warning signal for potential future actions.

The other factors, while also important, do not carry the same level of weight in predicting suicide risk. For instance, substance abuse can contribute to suicidal thoughts and behaviors, but the mere history of it doesn't independently predict suicide as strongly as violent behavior does. Recent life changes and social isolation can exacerbate feelings of hopelessness and despair but are often situational and may not be as deeply ingrained as tendencies associated with violent behavior.
