Direct and mediated model. β value represents standardized regression coefficient. Note that β₂ decreased when inserting a mediator into the model. A: Two alternative path analytic models explaining group differences between patients with bipolar I disorder and controls in delayed recall in the Korean-California Verbal Learning Test. R²=0.38 for the direct model and R²=0.50 for the mediated model. B: Two alternative path analytic models explaining group differences between patients with bipolar I disorder and controls in delayed recall in the Rey-Osterrieth Complex Figure Test. R²=0.35 for the direct model and R²=0.44 for the mediated model.
