Examining the unique contribution of parent anxiety sensitivity on adolescent neural responses during an emotion...

Parent factors impact adolescent's emotion regulation, which has key implications for the development of internalizing psychopathology. A key transdiagnostic factor which may contribute to the development of youth internalizing pathology is parent anxiety sensitivity (fear of anxiety-related physiological sensations). In a sample of 146 adolescents (M/SD_age = 12.08/.90 years old) and their parents (98% mothers) we tested whether parent anxiety sensitivity was related to their adolescent's brain activation, over and above the child's anxiety sensitivity. Adolescents completed an emotion regulation task in the scanner that required them to either regulate vs. react to negative vs. neutral stimuli. Parent anxiety sensitivity was associated with adolescent neural responses in bilateral orbitofrontal cortex (OFC), anterior cingulate, and paracingulate, and left dorsolateral prefrontal cortex, such that higher parent anxiety sensitivity was associated with greater activation when adolescents were allowed to embrace their emotional reaction(s) to stimuli. In the right OFC region only, higher parent anxiety sensitivity was also associated with decreased activation when adolescents were asked to regulate their emotional responses. The findings are consistent with the idea that at-risk adolescents may be modeling the heightened attention and responsivity to environmental stimuli that they observe in their parents.
