This study aims to identify research domains and detailed contents of art therapeutics in the United Kingdom by investigating the intellectual structure, and deriving implications for research in South Korea. The research targets were 202 original papers published in the “International Journal of Art Therapy: Inscape” from volume 1, number 1 to volume 23, number 3 (1996-2018). This journal is published by the British Association of Art Therapists. Excel, SEMI, COOC, WNET, and NodeXL programs were used as research tools. Based on the individual appearance frequency and simultaneous appearance frequency of 144 words extracted from the targeted research papers, the similarity coefficient was calculated. After visualizing the network, the intellectual structure was identified by the organizing contents of the papers related to each research domain. The results of this study are as follows. First, after grouping major research subjects, it was revealed that 41 subgroups were distributed in seven high-level groups. Second, 17 significant research domains were classified. After examining the detailed contents of intellectual structure, many studies on schizophrenia, learning disability, autism spectrum disorder, post-traumatic stress disorder and borderline personality disorder were found. Moreover, many studies had researched children’s drawings and images, and investigated new art therapy theories. Based on these results, implications were discussed for the advancement of art therapeutics in South Korea.
