ELS=early life stress cumulative severity; FDC=fiber density and cross-section; OFC=orbitofrontal cortex; NAcc=nucleus accumbens. Reward sensitivity model: adjusted R2=.11, F(9, 144)=3.15, p=.002. Punishment sensitivity model: adjusted R2=.08, F(9, 144)=2.41, p=.014. Age, ELS severity, race, and scanner acquisition were included as covariates; Race was coded as 1=White, 2=Racial-ethnic minority; Sex was coded as 1=male, 2=female.
