It has a range of prompts to stimulate thinking about critical success factors in programs relevant to Aboriginal and Torres Strait Islander people¡¯s lives. Ngaa-bi-nya was designed from an Aboriginal practitioner-scholar standpoint and was informed by the holistic concept of Aboriginal health, case studies with Aboriginal-led social and emotional well-being programs, human rights instruments, and the work of Stufflebeam. Aboriginal and Torres Strait Islander health and social programs have been described as suffering from a lack of evaluation. Ngaa-bi-nya is one of the few tools developed specifically to reflect Aboriginal and Torres Strait Islander peoples¡¯ contexts. It prompts the user to take into account the historical, policy, and social landscape of Aboriginal and Torres Strait Islander people¡¯s lives, existing and emerging cultural leadership, and informal caregiving that supports programs. Ngaa-bi-nya¡¯s prompts across four domains¡ªlandscape factors, resources, ways of working, and learnings¡ªprovide a structure through which to generate insights necessary for the future development of culturally relevant, effective, translatable, and sustainable programs required for Australia¡¯s growing and diverse Aboriginal and Torres Strait Islander populations %K Aboriginal and Torres Strait Islander people %K Aboriginal health %K evaluation methodology %K Indigenous peoples %K self-determination %U https://journals.sagepub.com/doi/full/10.1177/1035719X18760141
