Note: All covariate effects estimated in latent change score models. Unstandardized coefficients reported for measures normed to pre-intervention means and standard deviations in the total sample. *p < 0.01,†p < 0.05, α’ = 0.01. Constructs are latent composites of multiple measures. WM, working memory.
