Test Your Memory - Spanish version (TYM-S): A validation study of a self-administered cognitive screening test

Abstract

ObjectivesTo develop the Test Your Memory (TYM) - Spanish version (TYM-S), a self-administered cognitive screening test, in a Chilean older sample and to estimate its psychometric properties and diagnostic accuracy. MethodsThe TYM was translated into Spanish and adapted for a Chilean population to develop the TYM-S. Measures of global cognitive impairment and executive dysfunction were administered to 30 controls, 30 dementia patients, and 14 subjects with mild cognitive impairment (MCI). All participants' proxies were interviewed with assessments of dementia severity, functionality in daily living activities, and cognitive change. Convergent validity and internal consistency reliability of the TYM-S were estimated. Cut-off points, sensitivity, and specificity were determined to test its diagnostic capacity for dementia or MCI. ResultsRegarding convergent validity, the TYM-S was significantly correlated (p < 0.001) with global cognitive impairment (Mini-Mental State Examination: r = 0.
