For the whole brain analysis of the repeated-measures ANOVA revealed no significant changes in activity (interaction contrasts) in any region in the PT group as compared to the non-PT group at Time 2, under the ToM or GeN conditions. Likewise, no significant results were shown in the additional ROI analysis.As few studies have investigated the PT effect on brain function of mothers caring for children with ADHD, and to balance Type I and II error risks, we explored the potential PT effects by using more lenient threshold (Furthermore, planned within-group comparisons showed significantly increased activation in the left occipital fusiform gyrus in the PT group during the ToM condition at Time 2 as compared to Time 1 (Fig. Regions showing significant differences between Time 1 and Time 2 in the PT group during the RMET. The colored regions show significantly increased activation after PT intervention in the PT group. The statistical threshold was set at Regions showing significant differences between Time 1 and Time 2 in the PT group (within-group comparisons)The threshold was set at Additionally, associations between increased signal changes of the left occipital fusiform gyrus, and degree of reduction of RTs under the ToM condition and reduced PSI and PS (Time 1 vs Time 2) scores were investigated using the MarsBar Toolbox (
