Each cognitive domain's standardized Z score was used as the outcome variable in a linear regression of BDI-II score. The BDI-II estimate may be interpreted as the mean change in the cognitive domain corresponding to a 1-unit change in BDI-II score; for example, an increase of 10 in the BDI-II score leads to a mean decrease of 0.29 in the working memory domain score.
