The purpose of this study was to examine responsive art experiences in the reflection process of group art therapy cases for mourning using narrative inquiry, which is a qualitative research method, in an effort to determine the nature of self-reflection experiences. To conduct an autobiographical study as an art therapist, the researcher provided eight sessions of group art therapy for mourning to elderly surviving spouses who lived alone and were clients of this researcher, and the cases were recorded at the same time. In this way, reflective responsive art and writing were done, and the cases were described from the perspective of narrative inquiry. The process of looking back on and describing the ongoing cases based on responsive art contributed to connecting the clients with this researcher as a therapist, to enlarge the space of healing, and to provide this researcher with creative experiences through reflection in the art therapy process. This study is of significant because it investigated the process of the self-reflection experiences of an art therapist through “responsive art” to suggest how to develop the identity of art therapy and the professionalism of art therapists.
