Annotation | Although dementia screening tests are available, they have not gained widespread use in hospital or primary care settings in the US. This study aimed to develop a simple, standardised, performance-based test incorporating real-world activities to augment screening efforts in older populations: the Time and Change (T&C) test. A prospective cohort design was used, involving medicine and surgery services at an urban teaching hospital. From consecutive admissions, 776 participants aged 70-98 years, 14% with dementia, were enrolled. T&C ratings were validated against a reference standard based on the modified Blessed Dementia Rating Scale and the Mini-Mental State Examination (MMSE). Convergent validity with other cognitive measures, test-retest agreement, and inter-observer reliability were assessed. The T&C test had a sensitivity of 86%, specificity of 71%, and negative predictive value of 97%. The test demonstrated convergent agreement with three cognitive measures, agreeing most strongly with the MMSE. Test-retest and inter-observer agreement rates were 88% and 78%, respectively. Education explained 3% of the variance of the T&C test, compared with 13% of the MMSE. (AKM). |
