Abstract
Parents' emotional functioning represents a central mechanism in the caregiving environment's influence on adolescent affective brain function. However, a paucity of research has examined links between parental emotional arousal and regulation and adolescents' affective brain function. Thus, the present study examined associations between parents' self-rated negative emotion, parent emotion regulation difficulties, and adolescent brain responsivity to negative and positive emotional stimuli. Participants included 64 12-14 year-old adolescents (31 females) and their female primary caregivers. Adolescents viewed negative, positive, and neutral emotional stimuli during an fMRI scanning session. Region of interest analyses showed that higher parent negative emotion was related to adolescents' greater ACC and vmPFC response to both negatively- and positively-valenced emotional stimuli; whereas, parent negative emotion was related to adolescents' greater amygdala response to negative emotional stimuli only. Furthermore, parent emotion regulation moderated the association between parent negative emotion and adolescents' brain response to negative emotional stimuli, such that parents with high negative emotion and high emotion regulation difficulties had adolescents with the greatest affective brain response. Findings highlight the importance of considering both parent emotional arousal and regulation in understanding the family affective environment and its relation to adolescent emotion-related brain development.
