Narrative has been central to psychoanalysis from its inception. What has been explored less is the relationship between psychotherapy and interactive narrative. In particular, narrative therapy is a wellestablished practice in psychotherapy which shares central concerns with interactive narrative research and practice. In this paper, we explore the foundational role of narrative in psychotherapy and consider its interactive aspect. Then, we identify the overlap between interactive narratives and narrative therapy, and identify interactive narrative works which use this potential for therapeutic purposes. We also describe a concrete implementation, the board game Mind Stories, and introduce the concept of interactive narrative therapy.
