This scoping review synthesizes existing literature on the application of the capability approach (CA) to address the health and well-being of Indigenous Peoples across the globe. Academic and grey literature searches led to the identification of 20 papers for inclusion in the review. Findings reveal a growing interest in applying the CA to Indigenous health and well-being research, highlighting its potential to guide interventions and policies. The included studies indicate that the CA has been applied to individual capabilities such as facilitating access to services and collective capabilities linked to identity and traditional knowledge preservation. A key finding across the reviewed literature is the importance of incorporating Indigenous values into defining programmes and policies aimed at improving Indigenous Peoples' well-being. The review underscores the varied application of the CA by researchers aligning with the position of either Sen or Nussbaum, leading to contrasting methodological approaches. Results underscore the CA's potential as a culturally sensitive framework for participatory and locally embedded development of well-being interventions and policies.
