Figure 1. Discounting of future rewards and suicidal behavior.

Figure 1

A. Low-lethality suicide attempters and suicide ideators showed the strongest preference for immediate rewards, followed by the two non-suicidal comparison groups. In contrast, high-lethality suicide attempters were more willing to wait for larger rewards (F[4,109]=5.9, p<.001, effect size: η2=0.18; Tukey HSD: low-lethality attempters> high-lethality attempters =depressed=controls; ideators> high-lethality attempters=controls).

B. Willingness to wait for larger rewards was associated with suicide attempts that were better planned (r=.60, p=0.001)
