    AbstractStudies have assessed relationships between posttraumatic stress disorder (PTSD) symptoms and physiological reactivity concurrently; fewer have assessed these relationships longitudinally. This study tests concurrent and prospective relationships between physiological reactivity (heart rate and skin conductance) to a monologue procedure and PTSD symptoms in female assault survivors, tested within 1 and 3 months posttrauma. After controlling for initial PTSD and peritraumatic dissociation, 3 measures of increased physiological reactivity to the trauma monologue at 1 month predicted 3-month PTSD reexperiencing severity. Additionally, increased heart rate following trauma and neutral monologues at 1 month was predictive of 3-month numbing symptoms. Implications for the prospective relationship between physiological reactivity to trauma cues and PTSD over time are discussed.Copyright © 2010 International Society for Traumatic Stress Studies.
