This article summarizes the development of the caregiver–provider relationship assessment (CPRA) designed to measure family caregivers’ perceptions of relationship quality with health care providers. Using an online sample of family caregivers (n = 156), the patient reactions assessment (PRA) was adapted for use with family caregivers and subjected to principal component and reliability analyses. Analyses indicate that the CPRA factor structure is analogous to the original PRA scale, and Cronbach’s α for the three CPRA subscales range from .85 to .91. The tool can be used by clinicians and researchers in efforts to help family caregivers become more effective communicators in health care contexts.
