The Harmonized Cognitive Assessment Protocol is a substudy within the ongoing Health and Retirement Study (HRS). It is part of the HCAP Network, an ongoing international research collaboration funded by the National Institute on Aging (NIA) that seeks to measure and understand dementia risk by collecting a carefully selected set of established cognitive and neuropsychological assessments and informant reports to better characterize cognitive function among older people. HCAP collects data from the target respondent and a knowledgeable informant. The 2022 HCAP is the second wave the HRS HCAP substudy (wave 1 collected in 2016).
Respondent and Informant Data contain item and test score data.
