INTRODUCTION: This study investigated in a community sample associations of 2 different measures of unawareness of @entity2414 in @entity303 with @entity73 and behavioral and psychological symptoms of @entity303 . METHOD: Design-cross-sectional, population-based survey. Settings-community samples (n = 15 022) from 3 world regions (Latin America, China, and India). @entity1 -829 @entity1 with @entity303 identified from standardized interviews and diagnostic algorithms. Measurements-unawareness of @entity2414 was measured in 2 ways: comparison of @entity1 subjective report with either objective performance on memory tests or informant report (IR). Associations were investigated using prevalence ratios and Poisson regressions. Differences in frequency of unawareness were explored with McNemar tests for each region and agreement between variables calculated with Cohen k. RESULTS: The unawareness variable based on comparison with performance was associated with @entity73 , such as fluency (in China) and @entity73 (Latin America and India), and behavioral symptoms, such as @entity162 (Latin America) and @entity1833 (China). The unawareness variable based on IR was associated only with behavioral symptoms, such as @entity148 and @entity162 (Latin America). Frequency of unawareness was significantly higher in the unawareness variable based on performance in India. Agreement between the 2 unawareness variables was moderate in Latin America and China but only slight in India. CONCLUSION: Different ways of measuring unawareness are differentially associated with influencing factors. Informant-based unawareness measures may be more subjective and less sensitive than variables taking into account actual performance on cognitive tests.
