title: Effects of additional prolonged exposure to psychoeducation and relaxation in acute stress disorder.
abstract: We investigated the effect of prolonged exposure (PE) on the heart rate (HR) and skin conductance response to trauma-related stimuli in acute stress disorder (ASD). Forty recent trauma victims with ASD were randomly assigned to three sessions of either PE or supportive counseling (SC) with both groups also receiving psychoeducation and progressive relaxation. Assessments were carried out before and after treatment and again after 3 months. Four years later, patients were asked by telephone whether they had received further treatment. There were no significant group differences with regard to symptomatic improvement at the end of treatment. Both groups showed initial cardiac acceleration to trauma-related pictures. After treatment the PE group showed attenuation of the HR response and a reduction in spontaneous fluctuations (SF) whereas the SC group showed a decelerative (orienting) response and a marginal increase in SF. Following SC, 43% received further treatment compared to 9% after PE.
