Transdiagnostic Perspectives on Rumination and Stress Reactivity: Examining Autonomic Regulation, Negative Affect, and Social Stress in GAD and PTSD

This proposal investigates associations between rumination, autonomic regulation, and negative affect during social stress in individuals with generalized anxiety and/or PTSD. By examining the relationship between rumination and negative affect post-stress, findings will advance the transdiagnostic understanding of shared cognitive-emotional and physiological mechanisms underlying stress responses in these conditions.
