95 Examining the Utility of Demographically Adjusted Scores on the Community Screening Instrument for Dementia in Congolese Older Adults
Objective:Given the lack of comprehensive neuropsychological tools and neuropsychological services in Sub-Saharan Africa (SSA), cognitive screeners for dementia can be useful tools to screen for suspected dementia at the population level.

However, most available screeners have not been developed or validated in SSA populations. The Community Screening Instrument for Dementia (CSID) was developed for cross-cultural use, and it has a cognitive testing component and informant interview. We have previously demonstrated that lower years of education and female sex are associated with lower scores on the CSID. Here, we examine the utility of demographically adjusted CSID scores in a community sample of Congolese older adults.Participants and Methods:354 participants (mean age=73.6±6.7, mean education (years) =7.3±4.7; 50% female) were randomly recruited in Kinshasa, Democratic Republic of the Congo, and completed the CSID and the Alzheimer's Questionnaire (AQ) to examine functional abilities.

Raw scores were demographically adjusted for education and sex by adding 1 point for <12 years of education and 1 point for female. Cognitive impairment was classified as a total score below 25.5. Rates of impairment were compared between raw scores and demographically-adjusted scores. Demographic profiles were examined between both classificationsResults:Average raw CSID scores were 25.23 (SD=4.19) and average demographically-adjusted scores were 26.59 (SD= 4.09). Approximately 43.1% of the sample was impaired based on the raw CSID scores compared to 30.4% with the demographically-adjusted scores (x2= 12.334, p<.001). There was a higher proportion of females (n=95; 26.8%) classified as impaired with the raw SCID scores compared to the demographically-adjusted scores (n=62; 17.5%; x2= 8.87, p=0.003). Approximately 27.4% (n=97) of the participants classified as impaired with the raw SCID scores had primary education or less (i.e., 1-6 years) compared to 18.9% with the demographically-adjusted scores (n=67; (x2= 107.77, p<.001). Forty-five participants were re-classified as not impaired with the demographically-adjusted scores with the majority of these participants being female (73.3%), having primary education (66.7%), and being functionally unimpaired on the AQ (91.1% unimpaired).Conclusions:We demonstrate that raw scores on the CSID can lead to misclassification of impairment in females and in individuals with lower years of education. Demographically-adjusted scores on the CSID can help properly capture those with suspected dementia while reducing false positives. Given the effects of education and sex on performance, future studies should examine if demographically adjusted scores improve the sensitivity and specificity of the CSID in Congolese populations and compare its performance to other screening tools to determine the most appropriate screener for this population.</description><identifier>ISSN: 1355-6177</identifier><identifier>EISSN: 1469-7661</identifier><identifier>DOI: 10.1017/S1355617723004137</identifier><language>eng</language><publisher>New York, USA: Cambridge University Press</publisher><subject>Alzheimer's disease ; Cognitive ability ; Cross Cultural Neuropsychology/Clinical Cultural Neuroscience ; Dementia ; Dementia disorders ; Females ; Neurodegenerative diseases ; Neuropsychology ; Older people ; Poster Session 03: Dementia | Amnesia | Memory | Language | Executive Functions</subject><ispartof>Journal of the International Neuropsychological Society, 2023-11, Vol.29 (s1), p.294-295</ispartof><rights>Copyright © INS.
