Calibration of functional measures across multiple surveys. Lead Investigator: Eric Jutkowitz Institution : Brown University E-Mail : eric_jutkowitz@brown.edu Proposal ID : 1323 Proposal Description: We propose to develop a crosswalk between cognitive, behavioral, and functional measures which are captured in surveys. We plan to use the NACC-UDS in conjunction with survey data to develop crosswalks on measures of function and behavior. The primary NACC-UDS measures of interest include the FAS/FAQ and NPI. Demographic and clinical data captured in the NACC-UDS will be used to account for variation in responses.
