The research starts with the realization that the birth of a new trend of art called ‘self-confession art,’ which expresses the artist’s autobiographical story in a confessional way, is similar to the concept of art therapy. Self-confession art reflects the psychological trauma of artists, and analyzing self-examination through reemergence of the trauma can be a psychotherapeutic approach. The purpose of this research is to analyze the healing properties from the perspective of art therapy by studying self-confessional artists Louise Bourgeois and Tracey Emin. The indwelling healing factors in Bourgeois’ and Emin’s self-confession works are as follows. First of all is the ‘recovery of identity.’ It is the core factor of art therapy, in which they acknowledged themselves and objectified their issues through their works of art. The second factor is the ‘confessional self-disclosure.’ They felt catharsis through the expression of their psychological trauma to the public, and it eventually helped them emit negative emotions, converting them into positive emotions. Thirdly, it is a ‘repetitive expression.’ They repetitively expressed the pain trapped inside, which gradually brought the unconscious trauma out, curing the past wound consciously and enabling it to be restructured. Hence, the underlying healing properties of self-confession artworks from the perspective of art therapy are the recovery of identity, confessional self-disclosure, and repetitive expression.
