Linear regression of total intracranial volume, symptoms of psychopathology, and emotion dysregulation on gray matter volumes in areas of group difference centered within the left insula and right inferior frontal gyrus.

Notes. TIV = total volume in liters; DERS = Difficulties with Emotion Regulation Scale (Gratz & Roemer, 2004); YI = Youth Inventory (Gadow et al., 2002). Gray matter volumes are reported for the left insula and the right interior frontal gyrus. Similar results were found for the right insula, and are not reported.
