Indirect relation of visual association cortex gray matter volume and general psychopathology through executive function (EF). The indirect path analysis of visual association cortex (VAC) gray matter volume (GMV) predicting the p factor via the EF factor is shown. Direct paths from VAC GMV to the EF (Path A) and p factors (Path C) and from the EF factor to the p factor (Path B) are shown. The indirect path of VAC GMV to the p factor via EF was significant. The direct path from VAC GMV to the p factor remains significant with the inclusion of the EF factor in the model (Path C′). Standardized weights and 99% bias-corrected confidence intervals (CIs) are shown. Paths from gender, age, dummy-coded ethnicity and race, site, and total intracranial volume to VAC GMV and p and EF factors are not shown.
