Cognition

The Cross-Wave Imputation of Cognitive Functioning Measures: 1992-2022 (Final, Version 2.0) data release contains imputations for cognitive functioning data for HRS 1992 through 2022. The objective was to perform imputations for respondents with missing cognition data using a multivariate, regression-based procedure. We used a combination of relevant demographic, health, and economic variables, as well as prior and current wave cognitive variables to perform the imputations. Additional information about our imputation strategy is provided in the data description for this data product.

This dataset contains factor scores for HRS-HCAP that are harmonized to other HCAPs, in Stata .dta and generic .csv format. Included as documentation is the manuscript Harmonisation of later-life cognitive function across national contexts: results from the Harmonized Cognitive Assessment Protocols, the supplemental materials for that paper, and a more technical text file describing the scores in further detail.

This is a researcher contributed dataset that provides a total summary score for cognition using measures from the core HRS interview as well as three derived categories: Normal, Cognitively Impaired but not Demented (CIND), and Demented. We refer to these as the Langa-Weir Classifications (Crimmins et al., 2011). HRS also makes use of proxy respondents to reduce sample attrition. Therefore, this dataset also includes scoring of cognition based on data from proxy respondent interviews.

This is a researcher contributed dataset that provides predicted cognition and dementia measures developed in Hudomiet, Hurd, and Rohwedder (2022).
