When someone is in crisis, how they weigh risks and rewards can be a matter of life and death. This study explored whether people who had attempted suicide process decisions differently than other depressed patients and healthy individuals. They used tasks that mimic real-life choices, like the Iowa Gambling Task, to see how people learn from good and bad outcomes.
The results showed clear differences. Both depressed groups struggled with these tasks compared to healthy controls, but the suicide attempters stood out. They were less deterred by potential losses and made more impulsive errors on a task that required stopping a pre-set action. This pattern was even stronger in people who had attempted suicide impulsively or with violent methods. The study also found a link: the worse someone was at learning from losses, and the more they were willing to wait for a bigger reward later, the higher their reported suicidal intent.
This study involved 132 people, including 49 who had attempted suicide. It's important to note this was a snapshot in time, not a long-term look, and it can't prove that these thinking patterns cause someone to attempt suicide. It could be that the attempt, or the depression itself, changed how they make decisions. The findings suggest that a one-size-fits-all approach to suicide prevention may miss the mark, and that understanding an individual's decision-making style could be key to helping them.
