^aHigher PETS score = more burden. ^bAggregated mean of medical information, medications, medical appointments, and monitoring health scales. ^cAggregated mean of role/social activity limitations and physical/mental exhaustion scales. ^dFrom < $20,000/year (code = 1) to ≥ $100,000/year (code = 6). ^eCenters for Disease Control and Prevention, Healthy Days measure. ^fPatient Assessment of Chronic Illness Care: Higher score indicates better quality of care in the indicated domain. Scale administered in the REP sample only (N = 200)
