The purposes of this study are to implement Bibliodrama and examine its process. The format of Bibliodrama was used to understand the meanings and psychological phenomena of Christian young adults in the process of their improvement of interpersonal relationships and examine how these experiences would be manifested in their life courses. Based on Giorgi’s phenomenological methodology, the improvement process of interpersonal relationships was applied according to the research procedure. nine young adults in their twenties were selected at a church that had its first encounter with Bibliodrama. Along with a program of eight three-hour sessions, an indepth interview was conducted with the participants individually. The results of their interviews outcomes identified eight components and 27 subcomponents. The eight components include “check of life,” “maladaptive interpersonal relationship,” “experience of catharsis through Bibliodrama,” “understanding of oneself through role playing,” “interaction with others,” “creation of a new role,” “changes in one’s life attitude,” and “growth and challenge.” In the study, the participants expressed and experienced familiar stories in the Bible in connection to their personal lives, broadening their understanding of others as well as new perceptions of themselves. These findings indicate that experiences through interactions with others helped them form new relations and that they had enhanced experiences of more flexible interpersonal relationships thanks to growing positive thoughts and feelings.
