β1 = standardized regression coefficient for alcohol during pregnancy before controlling for mediator. β2 = standardized coefficient for alcohol during pregnancy after controlling for mediator.
FA = fractional anisotropy. LMP = left middle peduncle. λ⊥ = perpendicular diffusivity. WM = white matter. GM = gray matter.
Significance based on the difference in coefficients method (Clogg et al., 1992). For the DTI measures, df = 15, for the volumetric measures, df = 14.
