Objectives The aims of the study were (1) to assess the agreement and correlation between self-reported functional independence and observations of family caregivers in a heterogeneous population of community-dwelling older adults with disabilities and (2) to determine how self-reports and caregiver reports correlate with evaluator rated functional independence over time. Design Data were drawn from a larger, randomized controlled trial examining the effects of a caregiver-inclusive intervention on outcomes of care recipients and their family caregivers.
