Abstract
Objectives: The experience of traffic accident is a kind of the psychosocial stressors to person. The traffic accident-related patients may show the psychophysiologic hyperarousal. So we examined the differences of psychophysiologic response between patients with and without the memory of experienceing a traffic accident. Methods: Twenty-four traffic accident-related patients were divided into two groups according to ther memory of a traffic accident. In psychological assessment, levels of anxiety and depression were evaluated by State-Trait Anxiety Inventory, Beck's Depression Inventory, and Hamilton Rating Scales For Anxiety and Depression. Heart rate, electrodermal response (EDR), and electromyographic activity (EMG) were measured by biofeedback system, and systolic and diastolic blood pressure by automated vital sign monitor during baseline, task, and rest periods. We utilized script-driven imagery technique as a stressful task. The patients listened to the script describing their own traffic accident experience and were instructed to imagine the event during the task period. Statistically analytic data were obtained from the differences of psychological and psychophysiologic data between two groups. Results: The memory group did not show significantly higher EDR than the none memory group, but showed higher tendency during baseline, imagery, and rest periods. The memory group showed significantly lower EMG than the none memory group during rest period. However, there were no differences in other psychophysiologic reponses between the two groups. Conclusion: Our results showed that the memory group had higher tendency in autonomic arousal level such as electrodermal response than the none memory group. We suggest that physicians need to minimize repetitive imagery of traffic accident (reexperience), and decrease the autonomic hyperarousal in the treatment of traffic accident-related patients.
목 적 : 교통사고경험은 환자에게 정신사회적 스트레스요인으로 작용하며, 이로 인한 자율신경계의 생리적 각성수준이 항진되어 있을 것이다. 저자들은 교통사고와 관련된 환자중 교통사고에 대한 기억이 있는 군과 없는 군사이의 정신생리반응양상의 차이를 알아보고자 본 연구를 시행하였다. 대상 및 방법 : 전북대학교병원 정신과 외래 및 입원환자들중 24명을 대상으로 하였다. 모든 대상자들은 교통사고 관련 환자들이었으며, 연구목적상 이들을 교통사고상황을 기억하고 있는 환자군(12명, 연령
