Increased risk aversion with probabilistic loss outcomes (−log k loss) and increased loss aversion (λ) in depressed patients with a suicide attempt history. SA: Suicide attempters, ND: Nonsuicidal depressed patients, HC: Healthy controls. (A) Suicide attempters showed increased risk aversion (left and middle graphs) that reached significance in the loss condition (middle graph) compared to healthy controls. Suicide attempters generally exhibited risk aversion in the loss condition (−log k loss > 0), whereas nonsuicidal patients and healthy controls preferred risk-taking for probabilistic loss outcomes (middle graph). (B) Suicide attempters exhibited significantly higher loss aversion than did nonsuicidal depressed patients or healthy controls.
