Figure 1. Longitudinal Description of Caregiver Burden by Patient Diagnosis.

Figure 1

The figure shows the median caregiver burden score and interquartile range measured at baseline (time 0), 4 month, 8 month, and 12 month follow up. Caregiver burden was assessed during an in person interview with the caregiver using a 10 item short-form of the Zarit Burden Inventory scored on a 5 point Likert scale with total scores ranging from 1 – 40. The total sample size at base line was 179 caregivers (cancer 68, COPD 64, HF 47), 4 months was 165 (cancer 54, COPD 63, HF 48), 8 months was 137 (cancer 41, COPD 57, HF 39) and 12 months was 113 (cancer 27, COPD 51, HF 35).
