Occupational adaptation is a concept used relatively widely across occupational therapy and occupational science, but, like many core concepts within the disciplines, lacks clarity and consensus in how it is understood. Conceptually, it is poorly developed, abstract, contextual, and multidimensional generating confusion and debate. Consequentially, there are challenges in operationalising it in practice or research. This project aimed to enhance this understanding through investigating occupational adaptation in the context of occupational therapists adapting at work to maintain their professional identity. This context was identified as being of high importance to the profession due to the numerous challenges and opportunities occupational therapists are facing, including funding pressures, changing practice contexts, workforce profile changes, increasing demands for accountability and evidence of outcomes, and blurred and emerging roles. The link between a strong professional identity and ability to adapt as a profession or individual in turbulent times has previously been highlighted. However, occupational therapy’s professional identity struggle has been consistently discussed in the literature. Interrogating occupational adaptation within this context would, therefore, not only enhance the understanding of occupational adaptation, a pivotal concept which is philosophically and historically embedded in the occupational disciplines, but it would also provide occupational therapy with a honed understanding to guide its occupational adaptation in an everchanging landscape, to remain viable and seize opportunities. This research project had the overarching aim to understand the experience of occupational adaptation within the context of occupational therapists maintaining their professional identity.
