The psychophysiology of motor vehicle accident related posttraumatic stress disorder.
Heart rate, BP, and electrodermal responses of four individuals with PTSD secondary to motor vehicle accidents (MVAs) were measured while they imagined two separate scenes related to their MVA. Results showed reliable HR responses to these images. In addition, SBP and DBP also showed some responsivity to the images while skin resistance level changed reliably in only 2 of 4 subjects. Psychophysiological measurement could play a role in the assessment and treatment of MVA-related PTSD.
