This study is a qualitative analysis of expressive arts therapy case of migrant youth to present key experiences and meanings. From 6 July to 31 August, 2022, 10 sessions of expressive arts therapy for 60 minutes per session, once a week, were provided for a 13 year old female migrant youth who had experienced psychological trauma due to her mother's cancer treatment, migration, parents' divorce, and attempted self harm. For data collection, we used verbatim transcripts, photographs of work, observation journals, and in depth interviews with participants and carers, which we categorised into 'paralysed subjectivity', 'expressive subjectivity', and 'working subjectivity' using Braun & Clarke's (2006) method of central theme analysis. The outcomes of the study were categorised as "self defeating ineptitude," "reality we don't want to face," "pouring out the pieces of a broken heart," "safe permission to hurt," "starting line alone," and "treasure found in a volcano. Through this intervention, the migrant youth engaged in a grieving process that allowed them to safely express the impact of psychological trauma, including attachment relationship trauma, post migration adjustment stress, and the loss of home and friends. With a new understanding of self and a changed perception of interpersonal relationships with others, they integrated and reorganised their lives to create hopes for the future, which they viewed as post traumatic growth, which is the expression of self directed life agency. This study provides a basis for the value of expressive arts therapy as a crisis intervention for post traumatic growth.
