Negative valuation of ambiguous feedback may predict near-term risk for suicide attempt in Veterans at high risk for suicide.

ABSTRACT:

Background

Learning from feedback - adapting behavior based on reinforcing and punishing outcomes - has been implicated in numerous psychiatric disorders, including substance misuse, post-traumatic stress disorder, and depression; an emerging literature suggests it may also play a role in suicidality. This study examined whether a feedback-based learning task with rewarding, punishing and ambiguous outcomes, followed by computational modeling, could improve near-term prospective prediction of suicide attempt in a high-risk sample.

Method

Veterans (N=60) at high-risk for suicide were tested on a task of reward- and punishment-based learning, at multiple sessions across a one-year period. Each session was coded according to whether the participant had (1) an actual suicide att
