Previous studies have suggested that creative arts therapists who work in conservative societies must adapt their Western therapeutic ideologies to collectivist and traditional norms. Less is known about how these creative arts therapists construct and maintain their professional identity in diverse sociocultural contexts. Building on the literature that emphasizes the role of ethnic boundary work in professional identity processes, we examined how Arab drama therapists maintain, challenge, and negotiate ethnic boundaries in the process of professional identity construction.Participants were 38 Israeli-Arab drama therapists (36 female) working in Israeli-Arab schools. Data were collected through semi-structured interviews (27 participants) and playback theater groups (12 participants). Thematic analysis revealed three different forms of ethnic boundary work: "Distinguishing Arab identity from drama therapy", "Drama therapy as an act of challenging ethnic and gender boundaries", and "Negotiating ethnic boundaries within the context of drama therapy".The current study emphasizes the sociocultural context of boundary work by illustrating how Israeli-Arab drama therapists define their professional identity across ethnic, gender, and political tensions. We conclude with implications for research and practice.
