Mean latent change at post-intervention and the 4-month follow-up in the total sample.

Note: Unstandardized change scores reported for measures normed to the mean and standard deviation of the total sample at pre-intervention. All constructs are latent composites of multiple measures.*p < 0.01, †p < 0.05, α’ = 0.01. d is a standardized coefficient of change: d = Mean Change/√(Pre-intervention Variance). BS 95% CI, bias-corrected bootstrapped 95% confidence intervals; WM, working memory.
