When possible, the inverse U-type function was used to describe the nonlinear relationship between ADAS-cog effect and the rate of disease progression 13, 16, as shown in Eq. Conclusion: The low-literacy adaptation of the ADAS-Cog had good psychometric properties in this setting. In particular, the ceiling effect of the ADAS-cog scale should be noted when examining the baseline ADAS-cog effect on the rate of disease progression. Internal consistency was high (Cronbach’s α 0.884) and inter-rater reliability was excellent (intra-class correlation coefficient 0.905, 95% CI 0.804–0.964). The area under the receiver operating characteristic curve (AUC) was 0.973 (95% confidence interval (CI) 0.936–1.00) for dementia. Results: Median ADAS-Cog scores were 28.75 (interquartile range (IQR), 22.96–35.54) in mild/moderate dementia and 12.75 (IQR 9.08–16.16) in controls. Now, with the latest updates and ADAS enhancements, this MG continues to excel as a package. Cronbach's alpha () tested the reliability of ADAS-cog, and. Assessors were blind to diagnostic group. ADAS-cog was translated from the original English version to traditional Chinese with cultural and language considerations in Taiwan. Inter-rater reliability was conducted by two trained raters in 22 older adults (13 with dementia) from the same population. Participants were oversampled for lower educational level. Validation took place in a cross-sectional sample of 34 rural-dwelling older adults with mild/moderate dementia alongside 32 non-demented controls in Tanzania. Methods: Tanzanian and Nigerian health professionals adapted the ADAS-Cog by consensus. © Scandinavian College of Neuropsychopharmacology 2017 Objective: This study aimed to assess the feasibility of a low-literacy adaptation of the Alzheimer’s Disease Assessment Scale – Cognitive (ADAS-Cog) for use in rural sub-Saharan Africa (SSA) for interventional studies in dementia.
