Impact of stress and parenting on RSA trajectories in early adolescence

The current study investigated the effect of stress and parenting on one-year trajectories of physiological emotion regulation capacity among adolescents. Consistent with vulnerability-stress and allostatic load models, stress was hypothesized to be associated with less favorable trajectories of basal respiratory sinus arrhythmia (RSA) over a year. This relationship was further hypothesized to be moderated by parenting practices and adolescent sex. Participants included 150 adolescent participants (Mage = 13.04, SDage = .90, 51% female). Relationships between stress, parenting, adolescent sex, and RSA are described within
