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. We therefore examined the psychometric properties of the HCR Trust Scale in a random sample of adult primary care patients. Thirteen of the original 15 items fit the data best; a single-factor structure explained 67% of the variance in patient–provider trust. The Cronbach's alpha for the 13-item HCR Trust Scale—Revised was .96. © 2012 Wiley Periodicals, Inc. Res Nurs Health 35:397–408, 2012
