In this study, the acculturation process experienced by a Korean art therapist who re-acculturated to her own culture after being trained in the UK was investigated as the art therapist built her career. Through this investigation, the study aims to share the significance behind the experience with the academic community and the educational institution in the UK that provided the art therapy training. In order to achieve this, the author chose the autoethnographic approach, which reflects the researcher’s own experience in an absolute sense and, thus, can show a minority experience through recollection and insight. Additionally, the researcher conducted early coding and in-depth coding and derived themes based on the data in accordance with the open coding method to consider a subjective experience in social and cultural contexts. As a result, four main themes were derived: ‘Acculturation in the UK: acceptance of a different culture and growth’, ‘Re-entry culture shock in Korea: resistance and anger’, ‘Re-acculturation in Korea: relearning and understanding’, and ‘Establishing a multicultural identity as an art therapist: integration’. Discussion of the results is presented. [ABSTRACT FROM PUBLISHER]
