Abstract

The goals of this project were to examine (a) the concurrent and prospective associations between inhibitory control (as defined by performance, as well as neural activation and functional connectivity [FC] during the socially aversive relative to control and socially appetitive relative to control conditions on a socioemotional Go/no-go task) and depressive symptoms in adolescent girls; and (b) the mediating role of rumination. Participants included 90 mid-adolescent girls (Mage = 16.31 years, SD = .84, age range = 14.9 – 17.7) who completed a diagnostic interview, questionnaires, and a modified socioemotional Go/no-go task during an fMRI scan session. Depressive symptoms were associated with (a) less amygdala-cerebellum anterior lobe FC, more amygdala-precuneus, -posterior cingulate, and -right dorsolateral prefrontal cortex (dlPFC) FC, as well as more right dlPFC-precuneus FC during the socially aversive relative to control condition; and (b) more amygdala-superior temporal gyrus, -cingulate gyrus, -postcentral gyrus, and -right dlPFC FC, as well as more right dlPFC-postcentral gyrus FC during the socially appetitive relative to control condition. Rumination was associated with more amygdala-precuneus FC during the socially aversive relative to control condition. Finally, rumination partially mediated the association between amygdala-precuneus FC and concurrent depressive symptoms. Together, these results suggest that heightened neural processing of socioemotional information may represent a marker for depressive symptoms, and more effort by regulatory regions may be required to maintain inhibitory performance in depressed adolescent girls.
