Description
Muqi Guo and co-authors evaluate, in a 2025 study, a family-report questionnaire for cognitive decline in rural South Africa. When testing is hard and literacy low, asking a close informant how an elder's memory changed can fill the gap, but tools must be proven locally.
Data covered 676 participants and over a thousand informants across two survey waves, using a sixteen-item version translated into Shangaan. Informants had known participants for thirty-two years on average. The team checked completeness, internal consistency, and whether the items form one scale. They also tested whether swapping informants between waves shifts scores, a practical worry for long studies.
