The emergence of occupational science in non-English speaking countries is frequently hampered by diverse barriers to global collaboration, knowledge dissemination, and inclusion in international dialogue. Epistemological, cultural, and institutional resources may explain these barriers, yet these have not been explored within the discipline. This paper discusses three main issues and three priorities for action put forward by participants during sessions held at two separate, international occupational science conferences. The sessions aimed to engage the audience in critical reflexivity and dialogue around the challenges present when non-English speaking countries attempt to develop occupational science scholarship and possible ways to support global collaboration. To stimulate discussion, we used a participatory methodology, ‘Metaplan’. The sessions included a statements exercise, reflections presented by the authors, individual reflexivity, and small group debate. The findings are structured as a reflexive dialogue where participants’ voices, theory, and the authors’ reflections are interwoven to enrich discussion of the issues participants identified and priorities for action. This paper contributes to decolonizing the development of occupational science and promoting an international dialogue that is open to diverse worldviews, by drawing attention to the visible and invisible barriers that limit collaboration and inclusion of the diverse ways in which occupation is understood and enacted worldwide.
