Background: Stroke survivors and family caregivers often have incongruent appraisals of survivor cognitive, physical, and psychosocial function. Partner incongruence contributes to poor outcomes for survivors and caregivers. Objectives: This study explored whether partner incongruence: (1) differs by function domain; (2) increases or decreases over time, and; (3) is associated with self-rated health, distress, stress, and depressive symptoms.
