Task-based functional connectivity patterns: Links to adolescent emotion regulation and psychopathology

Adolescence is a developmental period characterized by heightened emotional reactivity, neurobiological changes, and increased rates of anxiety and depression. Emotion regulation (ER) difficulties—or the inability to effectively regulate one's emotions—have been theoretically and empirically conceptualized as a transdiagnostic factor implicated in virtually all forms of psychopathology among youth. The current fMRI study investigates how young adolescents’ ER abilities longitudinally mediate the relationship between their task-based (n=67) limbic-prefrontal functional connectivity values and subsequent levels of internalizing and externalizing symptoms. Findings revealed that adolescents with stronger limbic-prefrontal connectivity when viewing negative emotional images reported more ER difficulties one year later which, in turn, predicted higher levels of adolescent-reported internalizing and externalizing symptoms (with the exception of ADHD) two years later. This is the only study to date that provides compelling—albeit preliminary—evidence that ER problems longitudinally mediate the association between task-based functional connectivity patterns and future psychological symptoms among adolescents. Of note, participants were only scanned at baseline, limiting our ability to assess change in adolescents’ task-based functional connectivity patterns as a function of developing ER abilities or burgeoning psychological symptomology. In sum, rather than conferring risk for any particular disorder, our results suggest that functional connectivity and subsequent ER abilities may serve a transdiagnostic risk factor for psychopathology. These findings may inform future emotion-focused prevention and intervention efforts aimed at youth susceptible to future internalizing and externalizing problems.
