This study attempted to investigate the effect of unwanted sex consent on impact of event and post-traumatic growth, and to verify the moderating effect of cognitive emotional regulation strategy in the relationship between unwanted sex consent, impact of event, and post-traumatic growth. To this end, a survey was conducted on female college students with unwanted sex consent experience, and 41 data were finally analyzed using the PASW 18.0 program. The results of the study are as follows. First, unwanted sex consent showed a positive correlation with impact of event and post-traumatic growth. In addition, impact of event showed a positive correlation with the maladaptive cognitive emotional regulation strategy among the two sub-variables of the cognitive emotional regulation strategy. However, post-traumatic growth showed a positive correlation with the two sub-variables of the cognitive emotional regulation strategy: the adaptive cognitive emotional regulation strategy and the maladaptive cognitive emotional regulation strategy. Second, the moderating effect of the cognitive emotional regulation strategy between unwanted sex consent and impact of event was not significant. Third, the moderating effect of the cognitive emotional regulation strategy between unwanted sex consent and post-traumatic growth was significant. As a result of examining the two sub-factors of cognitive emotional regulation strategy, unwanted sex consent and adaptive cognitive emotional regulation strategy had a moderating effect on post-traumatic growth, and maladaptive cognitive emotional regulation strategy also showed a moderating effect on post-traumatic growth. These results mean that the positive and negative effects vary depending on which coping strategy is used after the unwanted sex consent event. In addition, it suggests that it is very important to explore which individual characteristics show different results even if they experience the same event.
