Cognitive task analysis and Indigenous research: bridging gaps to advance health equity

The aim of this study is to explore the application of Cognitive Task Analysis (CTA) within Indigenous research contexts. CTA is a psychological methodology for studying decision-making, problem-solving, attention, memory, judgement, and other cognitive processes required to complete certain goals. This review investigates how CTA has been applied in Indigenous research to identify opportunities for enhancing methods with Indigenous research expertise. A rapid evidence assessment methodology was employed to assess available data. The study spans healthcare and research settings across North America, Australia, and New Zealand. The review included 27 articles that employed various CTA methodologies, predominantly concept mapping and its derivatives. Studies demonstrated adaptability of CTA in exploring cognitive processes and decision-making frameworks relevant to Indigenous populations. The included studies provided limited detail on how CTA methods were adapted for Indigenous contexts, with methodological decisions often remaining implicit. While CTA holds considerable potential within Indigenous research settings, greater transparency in how methods are adapted, alongside clearer ethical and methodological guidance, may strengthen both rigor and cultural sensitivity. Future research may focus on developing culturally-responsive CTA frameworks that integrate Indigenous knowledge systems and promote Indigenous self-determination, alongside collaborative efforts and capacity-building initiatives to empower Indigenous researchers and communities.
