Background The KICA-Cog and KICA-Carer dementia screening tools were first co-designed with Aboriginal and Torres Strait Islander peoples in 2003. Two decades on, the tools have been reviewed and revised nationally to future proof for new generations whilst retaining their cultural and clinical validity. The consensus process aimed to refine the revised items and achieve agreement on their cultural and linguistic acceptability and sensitivity across cognitive domains. Methods Two national consensus panels were formed, an Elders and a clinical panel. Elders were recruited from Elders Governance Groups/Knowledge Circles at four sites, meeting for research yarns via videoconference with in-person support from local KICA researchers. The clinical panel comprised investigators experienced in cognitive assessment from diverse clinical backgrounds who provided feedback and voted via a live online document. An iterative process occurred with KICA researchers being the bridge: facilitating the panels; recording, synthesising and analysing data; noting queries and information for reciprocal knowledge exchange between panels; refining tool items; and repeating until agreement was reached. Results Following three rounds, agreement was achieved on all items by the clinical panel (9 members). Agreement was achieved for all rKICA-Cog items, and 12/13 items in rKICA-Carer by the Elders panel (9 members). The debated rKICA-Carer item was incorporated into another item as an example, with final agreement from panel members. Conclusion The rKICA-Cog and rKICA-Carer items have strong agreement from Elders culturally and linguistically, and from clinicians for encompassing necessary cognitive domains. The revised tools are ready for translation/back translation prior to validation.
