Functional brain networks identified as displaying a group (GD, CUD, HC)-by-choice (chase, quit) interaction in task-related engagement. (A) GD participants exhibited greater quit-relative chase-related engagement of a medial frontal network as compared to CUD and HC following outcomes, and as compared to CUD during decision-making. (B) CUD participants displayed negative quit-relative to chase-related engagement of a striato-amygdala network that differed from HC following outcomes, and differed from greater quit-related engagement in GD during decision-making. Regional integrations displayed at a voxel-level PFWE<0.001, k>100. **P<0.01; *P<0.05.
