This study aimed to develop a visual journal program for the recovery of university students with traumatic experience and tested its effects on their traumatized self-system, rumination, and mentalization. For these purposes, the investigator developed the visual journal program by analyzing the needs of research participants that consented to participate in the study and field experts and proposals in previous studies. The visual journal program implemented in the experiment group. A quantitative analysis was conducted to verify its effects between the comparison and control groups at the pre-test, post-test, and follow-up. The quantitative analysis results were supplemented with visual journals and experience reports in each session to demonstrate the effectiveness of the program. The findings were as follows: First, the experiment group showed significant differences in traumatized self-system, intrusive rumination, and mentalization; Second, the experiment group maintained the program effects for three weeks after the termination of the experiment. Finally, the program had positive effects on the traumatized self-system, intrusive rumination, and mentalization changes of both the experiment and comparison group. Based on these findings, the study discussed its significance and limitations.
