A sequential multi-method approach using focus groups, individual interviews, and quantitative instrument development procedures was used to develop and evaluate a scale to measure patient trust in health care providers (HCPs). The resulting 15-item Health Care Relationship (HCR) Trust Scale was tested for internal consistency, test-retest reliability, and construct validity. The Cronbach alphas were .92 (time 1) and .95 (time 2), respectively. Test-retest reliability was .59 (p < .01). The HCR Trust Scale did not correlate with the Marlowe-Crowne Social Desirability Scale (r = .20, p = .07) or the Rapid Estimate of Adult Literacy in Medicine scale (r = -.21, p = .13). Principal component factor analysis with varimax rotation revealed a three-factor solution that explained 69% of the estimated common variance in the HCR trust scale. Cronbach alphas for the 3 factors ranged from .81 to .89. Findings of this study support the use of the HCR Trust Scale for measuring trust in various HCPs by diverse patient populations. More work is needed to test the usefulness of the scale with a greater number of patients and in other chronic illness populations.
采用焦点小组、个人访谈和定量工具开发程序的顺序多方法，来开发和评估一个用于测量患者对医疗服务提供者（HCP）信任度的量表。由此产生的15项医疗保健关系（HCR）信任量表进行了内部一致性、重测信度和结构效度测试。克朗巴哈系数分别为0.92（第一次）和0.95（第二次）。重测信度为0.59（p < 0.01）。HCR信任量表与马洛-克劳恩社会期望量表（r = 0.20，p = 0.07）或医学成人识字率快速评估量表（r = -0.21，p = 0.13）均无相关性。采用方差最大化旋转的主成分因子分析揭示了一个三因子解决方案，该方案解释了HCR信任量表中估计共同方差的69%。这三个因子的克朗巴哈系数范围为0.81至0.89。本研究结果支持使用HCR信任量表来测量不同患者群体对各类HCP的信任度。需要开展更多工作，以在更多患者和其他慢性病群体中测试该量表的实用性。
