The measurement of cognition in large-scale cross-national surveys: lessons from the Health and Retirement Study International Network of Studies and the Harmonized Cognitive Assessment Protocol
By summarizing these experiences, this article informs future efforts in enhancing the comparability and validity of cognitive assessments for cross-national aging studies, providing insights into optimizing survey design for the accurate measurement of cognitive functioning, cognitive decline, mild cognitive impairment, and dementia. Insights also enable data users to identify the limitations of existing data, thus facilitating more informed decision-making in analytic projects.
