The validity of proxy responses on patient-reported outcome measures: Are proxies a reliable alternative to stroke patients ’ self-report?
ConclusionsBoth patient- and proxy-reported PROMs demonstrated strong validity. Only patient-reported PROMs were responsive to change, and proxies had worse validity for patients ≤ 3 months from stroke but better validity for patients > 3 months from stroke. These findings justify the utilization of proxy responses in stroke patients > 3 months from stroke.
