Abstract
Initial dementia prevalence estimates have revealed a significant burden of the disease in Indigenous communities in Amazonas, Brazil. However, the need for culturally adapted cognitive tools poses a critical challenge when assessing cognitive performance in these communities. This study addressed this issue by culturally adapting and providing validity indicators for the Brazilian Indigenous Cognitive Assessment (BRICA) tool in Manaus, Brazil's urban multiethnic Indigenous community.
Using a three-stage process and a stakeholder-engaged approach, the BRICA tool was culturally adapted in an urban multiethnic Indigenous community from Manaus, Brazil. The content validity index (CVI) examined inter-rater concordance between experts, while criterion and concurrent validity were performed using diagnostic consensus criteria in 141 Indigenous participants aged ≥ 50 years.
Findings showed evidence of content validity in terms of equivalence aspects (scale CVI [S-CVI] 0.93) and relevance ratings (S-CVI 0.85) between expert panels. The identified cut-off score of ≤ 33/39 on the BRICA demonstrated a sensitivity of 94.4%, specificity of 99.2%, positive predictive value of 94.4%, and negative predictive value of 99.2% for dementia diagnosis.
Using a stakeholder-engaged approach, we culturally adapted the BRICA tool for a Brazilian urban multiethnic Indigenous community. This comprehensive adaptation process resulted in favorable indicators of content, construct, and criteria validity for the BRICA tool. By addressing the existing bias in cognitive assessment within Indigenous communities, the BRICA tool represents a noteworthy breakthrough. Its implementation exhibits potential for improving the early detection and management of dementia among Indigenous groups.
Culturally sensitive tools are essential to assess cognition in Indigenous populations.An expert panel and stakeholders' perspectives were incorporated to design the Brazilian Indigenous Cognitive Assessment (BRICA) tool.A cognitive screening tool was adapted and validated using a stakeholder approach.BRICA is the first culturally sensitive cognitive tool for urban Brazilian Indigenous individuals.
