大学生における外傷後ストレス反応の改善に受容コーピングが及ぼす影響

According to the cognitive model of Posttraumatic Stress Disorder, coping is an important factor in improving Posttraumatic Stress Reactions (PTSR). Although many studies have examined the effects of coping on PTSR, it is not clear that temporal change of the relationship between coping and improving PTSR. Seventeen university students with improved PTSR and 12 university students with persistent PTSR answered a questionnaire containing seven categories of coping strategies. Participants indicated how often these strategies were used for improving PTSR “during the event,” “just after the event,” “after the event,” and “1 week before the survey”, retrospectively. The results showed that improved participants generally indicated higher acceptance of the event compared to participants with persistent PTSR after the event. Cognitive avoidance and distraction were higher in all periods for participants with persistent PTSR than for improved participants, and confession of the event was higher for participants with persistent PTSR than for improved participants at 1 week prior the survey. These results suggest that trying not to avoid the traumatic event and accepting just after it has occurred help improving PTSR.
