Partial model invariance was established for OA from early adolescent, and between FH groups. Although three of 4 pathways in each groups’ final model (right middle frontal gyrus to left middle frontal gyrus, right superior parietal lobule to right middle frontal gyrus, and right inferior parietal lobule to right superior parietal lobule) (ps>.172) were statistically comparable, comparison of FH groups on their shared final model indicated invariance on the pathway added from the right superior parietal lobule to the left middle frontal gyrus (χ2 =4.75, p=.029; dashed line Figure 4). This pathway was redundant in the OA model and not included in the final model. Of note, removal of the right superior parietal lobule to left middle frontal gyrus pathway, the connection that was statistically different between FH groups, decreased overall model fit much more in FHP than FHN models, underscoring the magnitude of group differences (Table 3). When SWM accuracy scores were included in each samples’ model of best fit, as related to each region of interest, and re-run one relationship at a time, increased SWM accuracy scores were
