Maternal Antecedents to Adolescent Girls' Neural Regulation of Emotion.

The purpose of this study was to investigate contributions of maternal emotional resources to individual differences in adolescents' functional connectivity during emotion regulation. Participants included 35 adolescent girls who completed an implicit emotion regulation task during fMRI. Mothers reported on the quality of their adult attachment and emotional awareness when youth were in elementary school. Higher anxious attachment and lower emotional awareness were significantly correlated with more positive amygdala-right ventrolateral prefrontal cortex connectivity, a pattern linked in prior research with ineffective emotion regulation and emotional difficulties. Further, there was an indirect effect of anxious attachment on adolescent connectivity through emotional awareness. These results suggest that compromised maternal emotional resources in childhood may be linked to atypical neural processing of emotions.
