Measuring patient-provider trust in a primary care population: refinement of the health care relationship trust scale.

Accurately measuring trust between patients and health care providers is important because low patient-provider trust can lead to poor treatment adherence and negative health outcomes. To measure patient-provider trust, we developed the Health Care Relationship (HCR) Trust scale. Findings from our initial use of the scale suggested the need to examine the scale's psychometric performance in a larger sample of adults with various chronic health conditions.
